Thank you 4 Davide

Hello,
The problem was that version 4.0.4 did not support the package so I tried with several old versions until 3.6.2 installs both climtrend and Rcmdr with its graphical interface !! solved and thanks again Davide !!Francesca

I'm glad you got success.

However, for anyone viewing this I must note that the proper name of the 
package is 'climtrends'. I'm not sure that you? ever spelled it 
correctly in your two postings to rhelp. R users will get little system 
help for poorly spelled package names. There is some hinting that occurs 
when using Rstudio, but that will only occur for packages that are 
already installed on one's system.

David.
