[R-sig-phylo] Ape

[pascal de Clarens]

Hello,

I use R on a mac (sierra)
I use « Iramuteq » working under R using page library

My problème is to change the ape version to get back to older version (from
5 back to 3.5)

I am not familiar with commands...

could someone help me?
If possible by giving the code lines i would have to put in the R terminal

Thanks a lot

Regards
