With a default installation of R on Windows platforms, packages are stored under Program Files/R/R-3.X.X/library. This often causes permission problems, as this directory is always read only by default, requiring the user to either change permissions for that directory or to change the directory where packages are stored later on option wise through modification of .libPaths in .Rprofile. For most

...once per page". I know I can use svg or pdf instead and that this would solve the problem, but problem is the journal (PloS) I would like to submit to only accepts EPS. So is there any solution to increase the quality in EPS, without having to rasterize everything to PNG? best regards, Tom Wenseleers [[alternative HTML version deleted]]

...) to export to Powerpoint, using the code available in ReporteRs. Especially for use in the classroom this would be super handy, as windows users are now pretty much tied to using bitmap-based PNG, thereby limiting the ease with which the final layout of R graphs can be edited ! best regards, Tom Wenseleers Prof Tom Wenseleers University of Leuven Naamsestraat 59 3000 Leuven, Belgium https://bio.kuleuven.be/ento/wenseleers/twenseleers.htm [[alternative HTML version deleted]]

...the R code to set it to something different: see http://cairographics.org/manual/cairo-cairo-surface-t.html for the call you would need to add. However, I would suggest that you generate a bitmap directly and use that, as PostScript does not support semi-transparency.

Or even, if it could be made possible to switch the type of BLAS used also on Windows, as is possible on Ubuntu...

I was recently testing R and RStudio on a high dpi 4K monitor under Windows and noticed that the plot window cannot be scaled or zoomed without affecting the relative sizing of all plot elements (line widths, font sizes, legend spacing etc). RStudio seems to try to overcome this by enabling dpi scaling for the plot window on high dpi screens, but this results in really fuzzy text and graphics

Dear all, Further to my previous message I now made a one-line convencience function to export your currently active graphics window/plot to either Word or Powerpoint in Office-native vector-based DrawingML format using either export2ppt(file="plot.pptx") or export2doc(file="plot.docx") : see
