#129 plots not working on Ubuntu 10.04 / R 2.15.1

[Ralf Tautenhahn]

plots do not work any more for me in rkward on Ubuntu 10.04.4

e.g. an initial plot(1,1) creates the window and the grid, but does not show the dot.

any plot command after that only creates an empty window but does not show anything.

Hi Ralf!

(I tried to follow-up by mail, but this did not seem to work. If a double-post appears, you'll know, what happened.)

Is this on the most recent svn revision (svn info)? Compiled from source? I
know some revisions had similar problems, but I am not aware of a current
problem. My testing is mostly with R 3.0.x and KDE >= 4.9, though.

Please try this:

• RMB click on one of the tool bars (e.g. the right hand one), check the
  "RKWard Debug Messages" window. Activate it.
• Run some simple plot commands in the console until the problem appears. Copy
  any output from the RKWard Debug Messages window.
• Change Configure RKWard->Debug->Debug level to "4", and repeat.

Also:

• What happens, if you follow up plot(1,1) with
  a) title("test")
  b) locator(1)

Most likely you can work around this problem by changing the device settings
at Configure RKWard->Onscreen Graphics, but of course it would be best, if we can track this down.

Regards
Thomas

There are no debugging message with debug level 2.

With debug level 4 I get:

• I changed setting to Embed Original Device and No Integration. That did not work.

• However, changing it to Platform default device does work.

Kind Regards,
Ralf

PS: Maybe I should upgrade to R3.0.1 ...

Hi!

Thanks for your testing so far. What happened (with the "RKWard native" / RK() device), when running locator(1) after plot(1,1)? Did this cause the plot to appear?

Could you try the following small modification in the sources?

• edit rkward/rbackend/rkwarddevice/rkgraphicsdevice.h
• add '//' (comment mark) at the start of lines 27 (#ifdef Q_WS_MAC) and 33 (#endif). (Or remove these two lines).
• recompile
• try again (making sure you really test the "RKWard native" / RK() device, of course)

Thanks!

[Ralf Tautenhahn]

Hi Thomas,

using locator(1) after plot(1,1) makes no difference. The plot does not show up (but I do see the location on the console).

when I comment out lines 27 and 33 in rkgraphicsdevice.h and try to compile I get this error (but it compiles fine when I put them back in):

[ 78%] Built target rkward.rbackend

Thanks!

when I comment out lines 27 and 33 in rkgraphicsdevice.h and try to compile I get this error (but it compiles fine when I put them back in):

Ok, comment out the lines again, then replace the offending lines 126 and 127 in rkgraphicsdevice.cpp with

if (col.isValid ()) area.fill (col.rgb());
else area.fill (qRgb (255, 255, 255));

then try once more.

Thanks!
Thomas

Hi Thomas,

perfect! rkward's native device now works with this patch!

Thanks,
Ralf

[Thomas Friedrichsmeier]

Hi!

perfect! rkward's native device now works with this patch!

Glad to hear that. That leaves the bug (in the unpatched version) somewhere between Qt and the X server. Could you provide version numbers for these two for future reference?

(Background: This patch causes all rendering to be done inside the rkward process, rather than in the X-server (which might utilize hardware acceleration). My impression - and rudimentary timing - is that this does not make too much of a difference for R plots, and so I guess I'll simply enable it for all X11-compiles for now. However, in case we run into performance problems at some point of time, it will be useful to know better, when using the X server for rendering is reliable, and when it is not.)

Regards
Thomas

[Ralf Tautenhahn]

libqt is 4:4.7.0~beta2
libx11 is 2:1.3.2
xserver-xorg is 1:7.5

Thanks again for fixing!
Ralf

[Donatas G.]

I wonder if I perhaps have the same bug: if I run hist(x), only an empty device appears. but if I resize the window just a bit, the plot does appear. If after that I run hist(y) (or any other plot command), the new plot does not get displayed till I resize the window again. I am using Version 0.6.1
on KDE 4.10.5, Kubuntu 13.04, from the repository
deb http://ppa.launchpad.net/rkward-devel/rkward-stable/ubuntu raring main

Please advise me if I should open another bug or just wait for this fix to reach the repos.

[Thomas Friedrichsmeier]

Hi Donatas!

This is almost definitely a different bug. Ralf was having trouble with the RK()-device, which is a new feature introduced after 0.6.1 (only in development versions, so far).

Please advise me if I should open another bug or just wait for this fix to reach the repos.

Go ahead, and open a new report. If you have any idea, when the problem has started, please include that bit of info. However, I'll be very short on time the upcoming weeks, so I won't promise anything.

You may want to give the current development snapshot a try (https://launchpad.net/~rkward-devel/+archive/rkward-dailys), where the RK()-device is the default device, already.

Regards
Thomas

[Thomas Friedrichsmeier]

Original issue fixed, long ago. Secondary issue as reported by Donatas not reproduced, since. Closing.

Donatas: Do let us know, if the issue still persists.
