[R] problem with creation of /doc/index.html

[Oleksandr Ocheredko]

I use macOS BigSur v.11.5
R v.4.0.5 macOS
package «ltable» does power analysis based on GSL-2.7
Xcode v.13.1

It goes smoothly with all OK on Checking, building, installing both with R and RStudio v. 1.3.1093
The only problem appears with Installing package in RStudio immediately after deleting it (no help.rd file found) which is solved just by rebooting RStudio
