Hi Bert
Yes, in this case which is not necessary. But in case NAs are involved
sometimes logical indexing is not a best choice as NA propagates to the
result, which may be not wanted.
x <- 1:10
x[c(2,5)] <- NA
y<- letters[1:10]
y[x<5]
[1] "a" NA "c" "d" NA
y[which(x<5)]
[1] "a" "c" "d"

I hope that you are doing well.

If you start R just using the regular command line version (not
RStudio), does
Sys.getenv("R_DOC_DIR")
point to /usr/share/R/doc ? The standard R startup script should do
that, but if it doesn't maybe you've got an override?
Or maybe you have R_DOC_DIR defined yourself?

Hello,
R 4.1.0 on Ubuntu 20.04.
My ls command on /usr/lib/R on my home computer gives what Rolf posted,
so I agree with every body that this is not an R issue and would insist
with RStudio and ask for their help again. They are generally helpful, btw.
I follow installation instructions to the
Jeff pointed out where the doc directory is installed in Ubuntu:
/usr/share/R/doc. So this is definitely an RStudio issue: perhaps it
got "tweaked", or perhaps Rolf installed a version meant for some other
distribution. In either case, off-topic in R-help, I think.
