Problem installing simDesign

i tried installing a package called "simDesign" on my desktop Rstudio.
Warning in install.packages :
package ‘simDesign’ is not available for this version of R. <-- -- that's what i got from the installation.

i couldn't get the updated package on CRAN, i will appreciate any help

Wouldyou provide us with the output of

A version of this package for your version of R might be available elsewhere,
see the ideas at

Warning in install.packages :
Perhaps you meant ‘SimDesign’ ?

Yes
I'm a newbie in Rstudio and checking out packages on CRAN always seems overwhelming.

You already posted the solution to your problem. Have in mind that R is case sensitive.

Yes i know that R is case sensitive, I've tried that two it's same results.

We need more information to help you, you should be getting at least a different error message. Please post the complete console output you get when you run this command.
