Re: [R] Error message "got a real'

   Yea, I checked that, but that wasn't the problem. I'm sending the input and    a much smaller file. It's in .csv format. The input is for the Mac, and    I'm beginning to think it might be a Mac issue. The program input lines    come from John Fox's program sem

        Hi all,
        I'm running the program sem on a Mac, but I'm getting a message that I
     think
        is quite general.  The error reads
         Error  in scan(file, what, nmax, sep, dec, quote, skip, nlines,
     na.strings,
        :
          scan() expected 'a real', got '10652)'
        The 10652 is the sample size coming from a .csv file where I have
     header =
        TRUE.

     It appears to be finding a parenthesis too.  That's not a real.
