I must use "ggPredict3d" and "ggPredict2d". So I'm following instructions and installing packages. But I can't. This message appears : Warning in install.packages :package ‘ggPredict3d’ is not available (for R version 3.6.1).
I'm looking for a solution in internet, but I don't find... Could you help me ?

But the problem is with package ggiraphExtra.
I installed it. But when i ticked it in package there was this message :
