您好,请问您解决这个问题了吗?我现在也遇到同样的问题
重新安装了‘quantreg’提示:
package ‘quantreg’ successfully unpacked and MD5 sums checked
Warning in install.packages :
unable to move temporary installation ‘C:\Users\liliy\Documents\R\win-library\3.3\file2594a2f1140\quantreg’ to ‘C:\Users\liliy\Documents\R\win-library\3.3\quantreg’这是什么原因呢?
先运行
install.packages("ggplot2")
install.packages("lattice")
install.packages("minqa")
然后运行
library(caret)
即可
先安装并加载了ggplot2和lattice这2个包之后,再次安装caret就可以了。
