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 foundThis 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 Heather Michel [[alternative HTML version deleted]]

The function name is dir.create(). But there might be some package that has a mkdir() function. Remember to quote the name; you probably need dir.create("specdata") Duncan Murdoch
Also ... it doesn't make sense to create a directory that already exists in the first place. Are you perhaps thinking about setting the working directory to "specdata"? That would be the setwd() command. B.
