[Xpose-general] "Error: subscript out of bounds" in compute.cwres

[Zufar M. <zuf...@gm...>]

Dear Xpose developers,

After installing xpose4specific package only (without installing
xpose4) I ran into an
"Error: subscript out of bounds" in compute.cwres function. Turns out
the error comes from section

                if (!is.null(CWRES))
                  data.cwres$CWRES = CWRES
                tmp <- installed.packages(priority = "NA")
                if (length(grep("xpose4", tmp)) > 0) {
                  xpose.version <- tmp["xpose4", "Version"]
                  xpose.text <- paste("from Xpose version", xpose.version,
                    sep = " ")
                }

due to line
               xpose.version <- tmp["xpose4", "Version"]

since "xpose4" was not installed.
Thank you
