[R] Package 'data.table' in version R-3.5.0 not successfully being installed

[Akhilesh Singh]

My thanks to Dr. John Fox and Dr. Duncan Murdoch. But, I have upgraded all
my R-3.4.3 libraries to R-3.5.0, and I have not backed-up copies of old
version. So, I would give a try each to the solutions suggested by John Fox
and Dengan Murdoch.

With regards,

Dr. A.K. Singh

You can see the errors in the package on this web page:

https://cloud.r-project.org/web/checks/check_results_data.table.html

Currently it is failing self-tests on all platforms except r-oldrel,
which is the previous release of R.  I'd recommend backing out of R
3.5.0 and going to R 3.4.4 if that's a possibility for you.

Yet another possibility is to use a version of data.table from Github,
which is newer than the version on CRAN and may have fixed the errors,
but that would require an installation from source, which not every
Windows user is comfortable with.
