Hello guys, I’m novice for R and I already downloaded R and Rstudio.  
Then I tried to install igraph and ggplot2 however I couldn’t do.  
Currently I use Windows 10 and R 4.0.2

install.packages(“igraph”)  
Warning in install.packages :  
unable to access index for repository [https://ftp.acc.umu.se/mirror/CRAN/src/contrib:](https://ftp.acc.umu.se/mirror/CRAN/src/contrib:)

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

Installing package into ‘C:/Users/Tsubasa/Documents/R/win-library/4.0’  
(as ‘lib’ is unspecified)  
Warning in install.packages :  
unable to access index for repository [https://ftp.acc.umu.se/mirror/CRAN/src/contrib:](https://ftp.acc.umu.se/mirror/CRAN/src/contrib:)

Warning in install.packages :  
package ‘igraph’ is not available (for R version 4.0.2)  
Warning in install.packages :

It’s showed like this.  
I want someone to help me with this problem.

Thank you

There was just a new release of `igraph` for R (1.2.6), for which the Windows binaries were probably not yet available. They now seem to be available, you should be able to install them now.

Thank you for your comment. But I can’t still install igraph.  
I tried to uninstall R and Rstudio but it didn’t work.

I’m lack of knowledge but I really need to know.  
So if you can help me out, I really appreciate.

It looks like this may have been a temporary CRAN connection issue, and unrelated to igraph. I would expect it to have started working since then.

Thank you for your advise. I could deal with it! The mainly because my laptop registered Japanese user name, I couldn’t install packages.  
I appreciate your support!
