I have tried to install the package gplots in R using
> install.packages("gplots")
However, it returns a warning and an error
Advarsel: unable to access index for repository
http://mirrors.dotsrc.org/cran/src/contrib
Advarsel: unable to access index for repository
http://mirrors.dotsrc.org/cran/bin/macosx/mavericks/contrib/3.2
Advarselsbesked:
package ‘gplots’ is not available (for R version 3.2.1)
I tried to install another package that should definitely be available (I've installed it before with this version of R) but it also failed with the same warning. Does anyone know why I can't access these repositories?
