tcltk-error

[nmueller18]

The message-box in 'readuserdata.R', line 93–98, leads to the following error on MacOS 10.13.6, R 4.0.3:

Fehler: .onLoad failed in loadNamespace() for 'tcltk', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: kann shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/tcltk/libs/tcltk.so' nicht laden: dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/tcltk/libs/tcltk.so, 10): Library not loaded: /opt/X11/lib/libfontconfig.1.dylib Referenced from: /usr/local/lib/libtk8.6.dylib Reason: Incompatible library version: libtk8.6.dylib requires version 11.0.0 or later, but libfontconfig.1.dylib provides version 10.0.0

This error is clearly related to 'tcl-tk'. You can get it to run on Mac with Quartz X11 but only after you jump through some loops which most users will not do.
I would try to find a simpler solution.

just removed this feature of a nice info-box. Warning has been adjusted.
A more explanatory example needed and feature for a vignette should be added.
