In R, starting from any working directory, I can do
setwd("~/Desktop") and this is consistent with how my linux distribution interprets cd at the command line. But Julia does not seem to recognize the ~/ notation:
julia> cd("~/Desktop") ERROR: chdir ~/Desktop: No such file or directory in systemerror at error.jl:38 in cd at file.jl:13 Is this a bug?

The command to change working directory is cd(dir::AbstractString=homedir()).
The working directory is just a file path on your computer that sets the default location of any files you read into R, or save out of R. In other words, a working directory is like a little flag somewhere on your computer which is tied to a specific analysis project.
The idiom is just different as you can see from the source. If you invoke cd() without arguments, it defaults to the home directory. The function homedir() can be used to prepend the home directory.
julia> homedir() "/Users/jeffw" julia> cd("/") julia> pwd() "/" julia> cd() julia> pwd() "/Users/jeffw" Combining things
julia> cd("$(homedir())/Desktop") julia> pwd() "/Users/jeffw/Desktop" The problem is that Julia doesn't expand the ~. You need to manually provide the full path. This is being worked on, but I'm on my phone right now and can't find issue.
