RStudio and caret package installation issue

There is a problem installing "caret" package in RStudio.

My system: macOS BigSur (11.6), Intel chip.

proper RStudio and R packages are loaded.

I tried to install packages with dependencies = TRUE. It fixed initial issue with dplyr. However the issue with "caret" persists.

Here is the error message.

instal.packages("caret", dependencies = TRUE)

tar: Retrying...
tar: gzip decompression failed
tar: Error exit delayed from previous errors.
Warning in install.packages :
'tar' returned non-zero exit code 1

ar: Damaged tar archive

The downloaded binary packages are in
/var/folders/xr/szwk8gmj3sd16fc8ryx7snbjq37zk9/T//RtmpvtBhfq/downloaded_package

library(caret)

Loading required package: ggplot2
Loading required package: lattice
Error: package or namespace load failed for ‘caret’:
.onLoad failed in loadNamespace() for 'data.table', details:
call: NULL
error: invalid version specification ‘before 1.12.0’

detach("package:caret", unload = TRUE)
Error in detach("package:caret", unload = TRUE) : invalid 'name' argument

Please, help

Thank you

PS. Strangely my other macPro with M1 chip has no problems at all.

indicates a corrupted file download for caret. You might try again with a different repository.

How do I change the source? in RStudio there is no such option that I am aware of.

Just install.packages(...). It selects the source on its own
