tutorials on R all afternoon. Many topics come close to my problem, but
none specifically address my situation where "specdata" is not a text file
but a list of small files in a folder.I found a command that should be more
right than mkdir, but it still won't work for my assignment. What argument
am I getting wrong?To recap, I can't access in R my data files that are on
my desktop. I need more understanding about how directories transfer
between Windows and R.

about R.The assignment says, "For this programming assignment you will need
to unzip this file and create the directory 'specdata".I unzipped the file
on my desktop, and my computer automatically created a new folder which I
renamed "specdata."However, when I try to make this directory within R
using mkdir, I get this:

I took notes on used an older version of R and were created more than 2
months ago.
