Re: [igraph] glpk_not_available

[Harun Pirim]

Thank you Gregory for the reply.

I didn’t install manually. The function used to work with an older version of R. It seems an issue with transition to R 3.4.4.

I tried installing Rgplk using install.packages() which gave the error:

* installing *source* package ‘Rglpk’ ...

** package ‘Rglpk’ successfully unpacked and MD5 sums checked

** libs

/bin/sh: line 0: cd: GLPK: No such file or directory

make: *** [GLPK.ts] Error 1

ERROR: compilation failed for package ‘Rglpk’

* removing ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/Rglpk’

Warning in install.packages :

  installation of package ‘Rglpk’ had non-zero exit status

I may try installing from source, however cluster_optimal() function will not be connected to the Rgplk package right away I guess.

Regards,

Harun

The package is Rgplk not GLPK, so that’s odd. Are you trying to install this manually? If so check the package name.

As for installation, it depends on your platform. If you’re on a Mac, there’s some kind of snafu on the cran mac build machine:

Install Rgplk from source if you can. On windows the binary may have been unavailable during the R 3.4.3 to 3.4.4 transition. Best,

Greg.

Dear All,

I ran cluster_optimal() function and got the message:

Warning in install.packages :
 package ‘GLPK’ is not available (for R version 3.4.4)

Any quick fix suggested?

thank you,
