As a follow-up to my request for help this morning, I have watched 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.
> dir.exists("specdata") TRUE
> load("C:/Users/rhmichel/Desktop/rprog-data-specdata/specdata/001.csv")Error: bad restore file magic number (file may be corrupted) -- no data loadedIn addition: Warning message:file ‘001.csv’ has magic number '"Date' Use of save versions prior to 2 is deprecated

Thank you for any help you can provide me,Heather Michel

I am trying to complete a homework assignment, but I know very little 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:
> mkdir (specdata)Error: could not find function "mkdir"> ?mkdirNo documentation for ‘mkdir’ in specified packages and libraries:you could try ‘??mkdir’> ??mkdir> pwdError: object 'pwd' not found
This makes me believe that some of the old command names have been updated in this version that is only 2 months old. Of course, the lectures I took notes on used an older version of R and were created more than 2 months ago.
Please tell me the command I should be using to create a directory named 'specdata' in R 3.2.3
