[Rd] Trouble installing packages when history mechanism is modified by user profile

[Henrik Bengtsson]

Using

if (interactive()) utils::loadhistory(file = "~/.Rhistory")

should solve your problem.  The reason is that install.packages() in
turn launches a non-interactive child R process that installs the
package.  When that process loads your startup file, it fails, because
that function can only be used in interactive mode.  Here's an
example:

$ Rscript -e "utils::loadhistory()"
Error in .External2(C_loadhistory, file) : no history mechanism available
