[igraph] Can not install igraph

[Frank Wiegand]

Hi

 

The following is explaining my problem:

 

 

> install.packages("igraph")

Installing package into ‘C:/Users/FW/Documents/R/win-library/3.4’

(as ‘lib’ is unspecified)

trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.4/igraph_1.1.2.zip'

Content type 'application/zip' length 8250396 bytes (7.9 MB)

downloaded 7.9 MB

 

package ‘igraph’ successfully unpacked and MD5 sums checked

Warning in install.packages :

  unable to move temporary installation ‘C:\Users\FW\Documents\R\win-library\3.4\file11013c922de\igraph’ to ‘C:\Users\FW\Documents\R\win-library\3.4\igraph’

 

 

 

Also manually copying the temporary installation to ‘C:\Users\FW\Documents\R\win-library\3.4\igraph’

does not solve the problem.

 

What to do?

 

THANKS!

 

Rgds
