패키지 등록관련질문

Question

인터넷에 연결되어있는데도 reshape2 패키지 설치가 안되는데 어떻게 해결해야하나요

Answer

강사분은 아니지만 구글링 해보니까 크랜 미러 설정 문제 같네요.

Sounds like you need to set a default CRAN mirror. Try this:

options(repos = c(CRAN = "http://cran.rstudio.com"))

If that does the trick, you can add it to your .Rprofile.

박스 내에 있는 커맨드 실행하시면 될 것 같습니다. 수고하세요.

Warning in install.packages :

package ‘resahpe2’ is not available (for R version 3.6.0)

Warning in install.packages :

이런 문구가 콘솔창에 뜹니다..
