Hello,
Is anyone having trouble with png image generation with 2.14.0 on Red Hat
6?
We recently updated our pipeline to Red Hat 6 (from 5) and R 2.14.0 (up
from 2.9.0) and R shell scripts that worked fine before are now breaking in
an unusual way.
The source of the problem seems to be centered around either label names or
the drawing of axii lines. Whenever I try to label or draw an axis the png
image stops being created. The rest of the shell script runs through
without error (even creating and filling some output files), but no more
images are drawn.
I've simplified the instance to a bit of code below.
For example, this shell script works:
*#!/bin/csh -f*
*R --no-save <<Eoi*
*ow <- options("warn")*
*rootDir <- "$1"*
*filePrefix <- "$2"*
*
*
*filename <- paste(rootDir,"/",filePrefix,".examplePlot.png", sep="")*
*png(file=filename, width = 1600, height = 1070, units = "px",type=c("cairo"
))*
*
*
*errors <- matrix(nrow = 5, ncol = 2)*
*for (i in 1:5) {*
* errors[i,1] <- i*
* errors[i,2] <- i*i*
*}*
*
*
*par(mfrow = c(2,1))*
*plot(errors[,2]~errors[,1], axes = F)*
*plot(errors[,2]~errors[,1], axes = F)*
*
*
*warnings()*
*options(ow) # reset*
*Eoi*
But the following does not:
*#!/bin/csh -f*
*R --no-save <<Eoi*
*ow <- options("warn")*
*rootDir <- "$1"*
*filePrefix <- "$2"*
*
*
*filename <- paste(rootDir,"/",filePrefix,".examplePlot.png", sep="")*
*png(file=filename, width = 1600, height = 1070, units = "px",type=c("cairo"
))*
*
*
*errors <- matrix(nrow = 5, ncol = 2)*
*for (i in 1:5) {*
* errors[i,1] <- i*
* errors[i,2] <- i*i*
*}*
*
*
*par(mfrow = c(2,1))*
*plot(errors[,2]~errors[,1], xlab = "", ylab = "", axes = F)*
*plot(errors[,2]~errors[,1], xlab = "", ylab = "", axes = F)*
*
*
*warnings()*
*options(ow) # reset*
*Eoi*
*#end R code*
*
*
Again, no errors or warnings appear to be thrown, it just seems to stop
writing to the png image. The same problem happens with jpeg() and tiff(),
but not with pdf(). [NOTE: I can not simply change to using pdf()]
Thank you for any assistance.
