problem with importing database from spss and excel

Hi, I am using R studio for the first time to learn the program.
I was trying to import file from spss or excel and got this message:

unable to access index for repository
cannot open URL ''

R probably looked for additional package to download and couldn't do it. Why?
Thanks in advance.

This could mean you can't access internet from your R installation.
Do you have a proxy or some firewall restricting internet access ?

What did you try exactly as command to get those errors ?

Finally I found the solution: I changed CRAN packages source from default to other from the list and R succeed to download all needed packages.

Glad you found a solution !
