当我输入
install.packages("swirl")
library(swirl)
我得到:
There is a binary version available but the source version is later:
binary source needs_compilation
mime 0.7 0.8 TRUE
Do you want to install from sources the package which needs compilation? (Yes/no/cancel) library("swirl")
Error in install.packages : Unrecognized response “library("swirl")”
我如何用这个在 R 中安装漩涡?
