Executing install.packages("Hmisc")
in R gives me the following error message:
Warning message:
In doTryCatch(return(expr), name, parentenv, handler) :
impossible de charger l'objet partagé '/Library/Frameworks/R.framework/Resources/modules//R_X11.so':
dlopen(/Library/Frameworks/R.framework/Resources/modules//R_X11.so, 6): Library not loaded: /opt/X11/lib/libSM.6.dylib
Referenced from: /Library/Frameworks/R.framework/Resources/modules//R_X11.so
Reason: image not found
Apologies that my system is set to French: the third line beginning with "impossible de charger ..." means "cannot load the shared object ...".
My system is Mac OS X Yosemite (10.10.5). My R version is 3.2.2 64-bit. This is the first time I have tried to install a package on R on this computer with this operating system.
