Error: package or namespace load failed for ‘summarytools’:
.onLoad failed in loadNamespace() for 'tcltk', details:

/builddir/vendor/build/lib/tcl8.6 ./lib/tcl8.6 ./lib/tcl8.6 ./library ./library ./tcl8.6.9/library ./tcl8.6.9/library
This probably means that Tcl wasn't installed properly.

In openSuSE, tcl and tk RPMs are installed (both version 8.6.7)
Microsoft R Open has its own tcltk in /opt/microsoft/ropen/4.0.2/lib64/R/share/tcl8.6 (which contains the required init.tcl file)
The above error message can be 'fixed' by using a command like
ln -s /opt/microsoft/ropen/4.0.2/lib64/R/share/tcl8.6 /builddir/vendor/build/lib/tcl8.6/
but that requires root privileges, appears messy, and is probably not what is intended!
I note that in /etc/alternatives/R, which is used to start Microsoft R, that environment variable $R_SHARE_DIR is set to (effectively) /opt/microsoft/ropen/4.0.2/lib64/R/share and $TCL_LIBRARY is set to (effectively) /opt/microsoft/R/open/4.0.2/lib64/R/share/tcl8.6, but in RStudio

(by contrast, the same command from the command line does have [1] "/opt/microsoft/ropen/4.0.2/lib64/R/share/tcl8.6/"
