[R] Installing packages in bulk

[Rich Shepard]

   For a new installation of R-3.5.1 I want to install all packages on
another host. I prepared a file, R-libraries.R, which contains
install.packages('BH, ...') for the entire list.

   When I source() this file on the new host and select a CRAN mirror I see
the message, "Warning message:
package 'BH,covr, <etc>
[...truncated]

   Do I need a space after each comma or is there something else wrong with
my syntax?
