Dear Toufik,

You've already had a suggestion to check whether RcmdrMisc is installed. It 
should have been installed automatically when you installed the Rcmdr package. 

If RcmdrMisc is installed, see whether you can load it directly via the command 
library(RcmdrMisc). If that too fails, you could try reinstalling RcmdrMisc via 
install.packages("RcmdrMisc"). 

Finally, you're using an old version of R. You might try installing the current 
version, which is 3.6.2. Then install the Rcmdr package by 
install.packages("Rcmdr").

I hope this helps,
 John
