set cairo as default bitmaptype in etc/Rprofile.site
as EB has cairo as a build dep, it might make sense to set cairo as a site default in EBROOT/lib64/R/etc/Rprofile.site by creating that file and adding options(bitmapType = 'cairo') to it
if that is not set, and although it is claimed that cairo is dfault, it seems to try to use X11/Xlib by default; which might not work at all (on typical hpc node env) and is apparently more crappy then cairo
Makes sense to me, although I didn't look into the specifics myself.
@fizwit Do you have any experience with this?
At my site we have documented:
If you see a message of 'unable to open connection to X11 display' when generating plots in RStudio then you can do one of the following:
- add
options(bitmapType='cairo')before plotting. - change the plot command to include
type="cairo". - add the text:
options(bitmapType='cairo')to the file~/.Rprofile(creating it, if required). This will ensure that the setting persists across each time you load RStudio on BEAR Portal.
We do also have people using R via X11 forwarding, but we've been moving those to the better experience of using RStudio Server. So, I am happy with the suggested change.
