[R] Yet another question about importing Excel *.xls files

[Jerry Floren]

Hi Gabor,

Thanks for all of your help and the additional code. Sorry, about the
confusion on my part about the directory and file names. 

Since my first posts, I have simplified file names, directory names, and the
spreadsheets by removing all the worksheets but the one needed. I tried this
code, but had the same error messages:

> library(gdata)

Attaching package: 'gdata'


        The following object(s) are masked from package:utils :

         object.size 

> read.xls("C:\\TestR\\Soiltest.xls", as.is = TRUE)
Converting xls file to csv file... Error in system(cmd, intern = !verbose) :
perl not found
Error in file.exists(tfn) : invalid 'file' argument
> 

Several times when loading packages, or even data, I see the "object(s) are
masked" message. Is that significant?

David Winsemius suggested that I need to install Perl. I hope to get that
done today, but need to get approval before it can be installed. I am using
Windows XP, but it looks like Strawberry Perl should work. I also use R
version 2.9.2 (2009-08-24). 

Thanks,
