By looking at http://www.R-project.org/posting-guide.html - http://cran.r-project.org/doc/manuals/R-data.pdf - Chapter 8 Reading Excel spreadsheets - you can also find my package xlsReadWrite which natively reads Excel files (Windows only).

I did use csv, but will probably, in future, use Petr's suggestion about reading from the clipboard: read.delim(clipboard) Because as it so happens, there was way too much unnecessary data in the spreadsheet. Plus I am using GNU/Linux, not Windows so some approaches won't work. I think this is now sorted.

The gdata package provides a read.xls() function that will read in an Excel file that will work on any system with Perl installed. -G On Mar 21, 2008, at 6:47AM , andy wrote: Hans-Peter wrote: I am trying to import an *.xls spreadsheet into R.

Re: [R] Importing an Excel spreadsheet
If you open the spreadsheet in Excel you can then do Save as... and select type CSV (comma-delimited text). Once you have the data in CSV format, you can use the R function read.csv to import the data. Cheers, Bryan andy wrote: Hello I am trying to import an *.xls spreadsheet into R.
