Hi, thanks for your reply.
I have tried that. When I use
install.packages("fs")
it says that it has worked but then when I retry downloading rlandsat from github I get the same
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘fs’
so I am not sure what I am doing wrong because I have already installed fs.
