我必须获得适用于R版本3.3的R软件包FactoMineR的最新版本。所以我尝试了:
install.packages('FactoMineR',repos='http://cran.us.r-project.org')
但是我得到了
Error in readRDS(file) :
cannot read workspace version 3 written by R 3.6.1; need R 3.5.0 or newer
In addition: Warning message:
package 'FactoMineR' is not available (for R version 3.3.3)
Error in readRDS(file) :
cannot read workspace version 3 written by R 3.6.1; need R 3.5.0 or newer
> version
有什么想法吗?谢谢!
