Hi
I realize that this question has been asked earlier also, but my problem is
slightly different.
I am running a rscript which runs for multiple datasets in loop and
generates png for every file in the loop. When I run this only local
machine (mac) it runs fine, just that that it takes very long to finish. I
am running it on server, it runs fine till some files but then starts
throwing the following error:
ERROR : unable to start device PNG
before firing the rscript when I check the status for capabilities it gives
me following:
> capabilities()
jpeg png tiff tcltk X11 aqua
FALSE TRUE FALSE TRUE TRUE FALSE
http/ftp sockets libxml fifo cledit iconv
TRUE TRUE TRUE TRUE TRUE TRUE
NLS profmem cairo ICU long.double libcurl
TRUE FALSE FALSE FALSE TRUE TRUE
When I run it and it terminates giving above error, then the capabilities()
gives following:
> capabilities()
jpeg png tiff tcltk X11 aqua
FALSE FALSE FALSE TRUE FALSE FALSE
http/ftp sockets libxml fifo cledit iconv
TRUE TRUE TRUE TRUE TRUE TRUE
NLS profmem cairo ICU long.double libcurl
TRUE FALSE FALSE FALSE TRUE TRUE
Note that png and X11 are turned FALSE once it terminates.
Why does this happen automatically? How can I rescue this?
For information, I am using R version 3.3.1 (2016-06-21).
