Installing igraph from binaries (1.3.0) gives me the following error:
> install.packages("igraph") Installing package into ‘C:/Users/b420054/Documents/R/win-library/4.0’ (as ‘lib’ is unspecified) There is a binary version available but the source version is later: binary source needs_compilation igraph 1.3.0 1.4.1 TRUE trying URL 'https://cran.mirror.ac.za/bin/windows/contrib/4.0/igraph_1.3.0.zip' Content type 'application/zip' length 9092295 bytes (8.7 MB) downloaded 8.7 MB package ‘igraph’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\b420054\AppData\Local\Temp\RtmpWCVcB1\downloaded_packages > library(igraph) Error: package or namespace load failed for ‘igraph’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/b420054/Documents/R/win-library/4.0/igraph/libs/x64/igraph.dll': LoadLibrary failure: The specified procedure could not be found.

I am on Windows 10, and R.version gives:

I have also tried to install using source, but getting header issues - will open another Topic on that.
