#38 Unable to load rjags in R.3.0.2.

[Anonymous]

Hello,

I'm trying to install rjags on Win7, R version 3.0.2.
JAGS version is 3.4.0.

In my computer, rjags is working fine with R version 2.15.1 (rjags_3-13, coda_0.16-1)

With v.3.0.2, I receive: (coda_0.17-1)

library(rjags)

Error : .onLoad failed in loadNamespace() for 'rjags', details:
call: packageVersion(pkg, lib)
error: package ‘rjags’ not found
In addition: Warning message:
package ‘rjags’ was built under R version 3.0.3
Error: package or namespace load failed for ‘rjags’

I went through the messages here, but I cannot locate any possible reason.

Any help would be appreciated.

You are not using the latest version of R (3.2.0) and so do not have access to the latest version of rjags (3-15). Try upgrading.

[Anonymous]

Thank you for your prompt reply.

I understand that the latest version should ensure a better compatibility. As long as this concerns myself, I'm running R on a controlled environment (e.g. not as an admin) and therefore I am not able to update the R version on-the-fly (needs ticket to IT, and time for evaluation, and re-installation of libraries, then further evaluation on existing running code, etc.). In other words, it can merely be a distant option.

On the other hand, I read on CRAN rjags specifications, that rjags 3-15 requires:

• R (≥ 2.14.0), coda (≥ 0.13)

If this compatibility issue is unresolved otherwise, shouldn't that requirement reference be changed to R (≥ 3.0.2), to prevent future misunderstandings with the rest CRAN users?

Many thanks again,

Ath.Tsakonas

[Martyn Plummer]

Sorry, my mistake. I thought rjags_3-15 would not be available for R 3.0.2 but checking the CRAN web site I see that it is.

It looks like you have a broken installation of rjags. Try typing

packageDescription("rjags")

at the prompt and see what happens.

This turns out to be a bug in R itself. The packageDescription() function does not work when your library is on a network drive (drive J in your case). I have confirmed this on my own network.

I shall push a new version of rjags with a workaround, but will also fix the bug in R.

[Anonymous]

Hi!

I get a similar message with newest version of R and JAGS installed:

Error : .onLoad failed in loadNamespace() for 'rjags', details:
call: fun(libname, pkgname)
error: Failed to locate any version of JAGS version 3

The rjags package is just an interface to the JAGS library
Make sure you have installed JAGS-3.0.0.exe or higher from
http://www.sourceforge.net/projects/mcmc-jags/files

Error: package or namespace load failed for ‘rjags’

Do you have any solution ideas for this problem?

[Martyn Plummer]

When you say the newest version of JAGS, do you mean version 4.0.0? Because you then need the corresponding version of the rjags package, i.e. rjags_4-3. It is not yet available from CRAN but you can download it here:

http://sourceforge.net/projects/mcmc-jags/files/rjags/4/rjags_4-3.zip/download

[Anonymous]

It helped. Thanks friend, you are great. Earlier i wasted hours to find a solution on the google...

Hello,

I use R 3.4.0 and Installed rjags_4-6 on my Windows 7 pc, and jags doesn’t seem to work. The error message I get is:

Error: package or namespace load failed for ‘rjags’:
.onLoad failed in loadNamespace() for 'rjags', details:
call: fun(libname, pkgname)
error: Failed to locate any version of JAGS version 4

The rjags package is just an interface to the JAGS library
Make sure you have installed JAGS-4.x.y.exe (for any x >=0, y>=0) from

Would you help me please?

[Martyn Plummer]

Did you do the thing that the error message asks you to do?

[Anonymous]

I see! It worked. Sorry, my mistake. Thank you very much.

Hello
I am having trouble to load the rjags package on R 3.4.3. The package had downlaoded properly as i can see it on the right side of the RStudio but I am unable to load it

Error: package or namespace load failed for ‘rjags’:
.onLoad failed in loadNamespace() for 'rjags', details:
call: packageVersion(pkg, lib)
error: package ‘rjags’ not found

I tried to uninstall R and JAGS multiple times and dowload different versions of JAGS (3 and 4) but none seem to change anything.

I tried
devtools::install_url("http://sourceforge.net/projects/mcmc-jags/files/rjags/4/rjags_4-4.tar.gz",
args="--configure-args='--with-jags-include=/Users/casallas/homebrew/opt/jags/include/JAGS
--with-jags-lib=/Users/casallas/homebrew/opt/jags/lib'")
But I get :
Installation failed: Command failed (1)

I have also tried installing from the rjags source file:
install.packages('~/Downloads/rjags_4-6.tar.gz', repos = NULL, type="source")
But still get the same error message.

Any ideas?
Thanks

This looks like a configuration problem with your R library. Can you load the coda package?

library("coda")
packageDescription("coda")

If this does not work, then try

.libPaths()

to see where R is looking for your packages. According to the output, the packages are installed in an SMB-mounted drive:

\\uniwa.uwa.edu.au/userhome/students3/18719303/My Documents/R/win-library/3.5

However, I don't think the double backslash SMB notation is going to work when R looks for your library (Backslash causes a lot of problems in strings in R). If the drive is mounted with a drive letter then use that, and make sure you have only forward slashes in the file path, e.g.

Z:/My Documents/R/winlibrary/3.5

Let me know if this works.

Hi Martyn,

Thank you for your reply.
I can load the coda package.

I found where the rjags package was loaded to and it was in the H drive.
This is what I tried and got the same error message:

library("rjags", lib.loc="H:/My Documents/R/win-library/3.5")
Loading required package: coda
Error: package or namespace load failed for ‘rjags’:
.onLoad failed in loadNamespace() for 'rjags', details:
call: packageVersion(pkg, lib)
error: package ‘rjags’ not found

I then tried:

.libPaths("rjags")

This showed that neither rjags nor coda were in the System Library.

Does this shed any light on this problem?

Thanks!
Evelyn

[Martyn Plummer]

This is still very mystifying. Try

file.access("H:/My Documents/R/win-library/3.5/rjags")

and

file.access("H:/My Documents/R/win-library/3.5/rjags", 5)

This is the point in the code that loads the rjags package where the error occurs.

[Anonymous]

Hi Martyn

A colleague found the problem.
Rstudio was loaded on to the university server which wasn’t allowing packages being installed as I don’t have the admin rights.
When we loaded Rstudio on to a local disk, rjags loaded fine.

It wasn’t a bug after all.

Thank you for your help!

Hi, if this chain is still active! I'm trying to load Rjags and getting the following error message in RStudio upon calling library(rjags):

library(rjags)
Error: package or namespace load failed for ‘rjags’:
.onLoad failed in loadNamespace() for 'rjags', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/libs/rjags.so':
dlopen(/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/libs/rjags.so, 10): Library not loaded: /usr/local/lib/libjags.4.dylib
Referenced from: /Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/libs/rjags.so
Reason: image not found

I've checked my library and the file '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/libs/rjags.so'
is indeed there -- so I don't think the library reference is the problem.

When I open the file '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/Meta/package.rds ' ,
I get the error message:

Error in load("/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rjags/Meta/package.rds") :
bad restore file magic number (file may be corrupted) -- no data loaded
In addition: Warning message:
file ‘package.rds’ has magic number 'X'
Use of save versions prior to 2 is deprecated

I have downloaded the most recent version of JAGS at the link: https://sourceforge.net/projects/mcmc-jags/ (using the website)

Any suggestions for how to solve this?

Thank you,
Abigail

Hello Martin

I started to have the same problem after I updated Rstudio (i had to, graphics were not working anymore).

I'm running a Win10 machine with R 4.1.1 and JAGS 4.3.0.

I got the following error message:

Error: package or namespace load failed for ‘rjags’:

Hello, I m getting the same issue, that i have R 4.1.1 and JAGS 4.2.0 but getting similar so how did you solve it

[Mário Mota-Ferreira]

Had to go back to a previous version (4.0.2)

[Mário Mota-Ferreira]

Just an update.
It seems the problem is with the R version. I'm able to work with an older version of R (4.0.2)

[Martyn Plummer]

The problem was a bug introduced in rjags_4-11. I have fixed it in rjags_4-12, which has just been uploaded to CRAN.

I made some changes for the new R toolchain, which is 64-bit only, but accidentally broke the code that reads the Windows registry to find JAGS. This bug was not detected by CRAN because they use a hard-coded path to JAGS.

[Mário Mota-Ferreira]

Thanks Martyn!

Do we need to update R or just rjags?

Cheers
