R has no graphics abilities on Debian buster #27163
Description
Seen in 8.7.beta1, but probably from 8.6 (i. e. the switch to using th library):
> 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 TRUE TRUE TRUE
Similarly, one can't install the R package "Cairo". This entails the loss of creating graphics files from R, which is exceedingly annoying...
One of the strengths of R being its graphical abilities, losing them is, IMNSHO, a critical problem.
