在我尝试加载Rcpp之前,Caret运转良好,这一切都搞砸了.
Caret was working fine until I tried to load Rcpp and it messed everything up.
我搜索了插入符号中类似问题的答案,但发布的解决方案似乎不适用于我的问题.我关注了:
I searched the answers for a similar problem with caret but the solutions posted did not seem to work on mine. I followed:
install.packages("caret", dependencies = TRUE)
但这没用.
推荐答案
我建议您检查R版本.我将版本更新为3.5.1,它可以完美运行:)
I would suggest you to check the R version. I updated the version to 3.5.1 and it works perfectly :)
仅Mac –使用updateR
Mac only – use updateR
类似于安装程序,updateR是用于在Mac OS上帮助更新R的软件包.
Similar to installr, updateR is the package to help updating R on Mac OS.
您需要的R代码是以下5行:
The R code you will need is these 5 lines:
install.packages('devtools')#假设尚未安装
install.packages('devtools') #assuming it is not already installed
库(devtools)
library(devtools)
install_github('andreacirilloac/updateR')
install_github('andreacirilloac/updateR')
库(updateR)
updateR(admin_password ='管理员用户密码')
updateR(admin_password = 'Admin user password')
