Dear all,
I seem to have a similar problem since yesterday but with ggplot2 and isobande. When trying to install the tidyverse I get this:
install.packages('tidyverse')
also installing the dependencies ‘isoband’, ‘ggplot2’
Warning in install.packages :
unable to access index for repository https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6:
cannot open URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6/PACKAGES'
Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘isoband’
Do you want to attempt to install these from sources? (Yes/no/cancel)
Attempts to install form source then fail ....
I'd massively appreciate any help. I have the newest version of R (version 3.6.3) on my mashine.
Greetings from social isolation in Vienna!
