I am running on Mac os mojave 10.14.6.
If i try install.packages("ggplot") I get the following:
There are binary versions available but the source versions are later:
binary source needs_compilation
rlang 0.1.6 0.4.5 TRUE
ggplot2 2.2.1 3.3.0 FALSE
If i choose no then I get the following error
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘rlang’ 0.1.6 is being loaded, but >= 0.3.0 is required
So I need 0.3.0 in order to get 'ggplot2'. I also tried using a link to install 'rlang' 0.3.0 but get a message it is not available (for R version 3.3.1) which is the version I need to be using.
