I couldn't see any differences between R-3.3.3 (which works) and
R-3.4.0 (which doesn't) until I got to here, a few lines before the
download.file line:
Browse[2]>
debug: dest <- file.path(tempdir(), paste0("repos_", URLencode(repos,
TRUE), ".rds"))
Browse[2]>
When I check out those directories in a terminal, there's a big diffrence:
With R-3.4.0
~ > ll /tmp/RtmpFUhtpY
total 4
drwxr-xr-x 2 hrapgc hrapgc 4096 May 31 10:45 downloaded_packages/
-rw-r--r-- 1 hrapgc hrapgc 0 May 31 10:56
repos_http%3A%2F%2Fcran.stat.auckland.ac.nz%2Fsrc%2Fcontrib.rds
With R-3.3.3
~ > ll /tmp/RtmpkPgL3A
total 380
drwxr-xr-x 2 hrapgc hrapgc 4096 May 31 11:01 downloaded_packages/

repos_http%3A%2F%2Fcran.stat.auckland.ac.nz%2Fsrc%2Fcontrib.rds
So, if I could figure out what makes *that* difference I could get
somewhere. I see there's considerably extra code in the newer of the
two versions of available.packages() but being a bear with a small
brain, I can't figure out what differences should be expected. I have
no idea what populates those 'dest' directories.
TIA
