Also, check the settings of R_HOME and/or R_LIBS.

Look at section 6.1 of the R Installation and Admin manual.
6.1 Default packages
The set of packages loaded on startup is by default
getOption("defaultPackages")
[1] "datasets" "utils" "grDevices" "graphics" "stats" "methods"
(plus, of course, *base*) and this can be changed by setting the option
in startup code (e.g. in ~/.Rprofile). It is initially set to the value
of the environment variable R_DEFAULT_PACKAGES if set (as a
comma-separated list). Setting R_DEFAULT_PACKAGES=NULL ensures that only
package *base* is loaded.
Changing the set of default packages is normally used to reduce the set
for speed when scripting: in particular not using *methods*will reduce
the start-up time by a factor of up to two. But it can also be used to
customize R, e.g. for class use. Rscript also checks the environment
variable R_SCRIPT_DEFAULT_PACKAGES; if set, this takes precedence over
R_DEFAULT_PACKAGES.

Hi,
When starting an embedded R I encounter the following issue under certain
conditions:
```
Error: package or namespace load failed for ?utils? in if
(.identC(class1,
class2) || .identC(class2, "ANY")) TRUE else {:
missing value where TRUE/FALSE needed
```
(more such errors for grDevices, graphics, and stats)
And in the end:
```
Warning messages:
1: package ?utils? in options("defaultPackages") was not found
2: package ?grDevices? in options("defaultPackages") was not found
3: package ?graphics? in options("defaultPackages") was not found
4: package ?stats? in options("defaultPackages") was not found
```
While the embedded R appears functional, no package can be loaded.
The erorr message from R (`missing value where TRUE/FALSE needed`)
suggests
that R should be able to catch the underlying issue (I am yet to find
what
it is) earlier and with this make the task of troubleshooting easier.
Best,
Laurent
