What has been already released cannot be affected, obviously, but you can release a new version under a different license if you have the legal right to do so.
Thank you very much Duncan and Simon for your replies.
The package I'm asking about has 1 author [aut] (me) and 1 contributor
[ctb] in the 'Author' field of the DESCRIPTION file. Both of them hold
the copyright of the package.
In case we want to change the licence. Do the 2 authors write something
particular in the next submission to CRAN ?
Do we need to provide some written document to CRAN ?
What Duncan means with
"If you are distributing the package on CRAN, you'll have to ask them
whether they'll still choose to distribute your package after the change"
May CRAN to decide not to distribute the package because of the change
in the licence ?

If the package we are talking about is pure R code, with only some
dependencies to other R packages, what are the implications of:
