I am student and I have to develop R shiny apps during my internship.
I have realized an appli which worked well,
and now the same app doesn't work anymore and I have this message for each packages install (here for leaflet) :
Erreur : package or namespace load failed for ‘leaflet’ in library.dynam(lib, package, package.lib):
The 'htmltools' DLL cannot be found: maybe it is not installed for this architecture?
I have reinstall R and each library with dependencies=TRUE, but nothing works...
Is there somebody who can help me ? One day that I am trying to figure out ...
Yhanks a lot
