I am trying to install devtools on Ubuntu 16.04 R. I have been able to install several packages, but currently, in my R session, when I type:
install.packages("devtools")
I receive:
Fatal error: cannot create 'R_TempDir'
Upon issuing the tempdir() command in R, I see that my temporary directory is located at tmp/RtmpD54Esf. I tried: rm -r tmp/RtmpD54Esf. But the problem remains.
I also tried df -h which results in:
Filesystem Size Used Avail Use% Mounted on
udev 32G 0 32G 0% /dev
tmpfs 6.3G 9.7M 6.3G 1% /run

/dev/sdc1 511M 4.7M 507M 1% /boot/efi
tmpfs 6.3G 40K 6.3G 1% /run/user/1004
I am not sure if the problem is that /dev/sdc2 is full. It appears to not be a directory. I tried sudo umount -f /dev/sdc2 and sudo umount -l /dev/sdc2 but still the problem persisted.
I have searched for several hours but most suggestions to fix this error revolve around erasing contents in the temp directory and unmounting the largest space from df -h. I feel I have tried both these suggestions and am still seeing the error. I do not have lots of Linux management experience and was hoping that by asking this question and following advice very carefully, I can identify if I may be misinterpreting the advice usually available. Thank you for your suggestions!
