I’ve mostly used head(), tail(), and View() to look at tables in R, but I wonder if anyone uses anything more sophisticated. I recall reading that there were R <-> Excel interfaces available (based on COM or XLLoop?) – does anyone use one to use Excel (or OpenOffice) to display data frames during an R session, and not necessarily just result the final result exported to a csv file?
Edit: Thanks for all the suggestions. I guess I should have specified that I was running Emacs+ESS on a Mac primarily (which disqualifies COM and Deducer), though I also switch to Linux and Windows on occasion. I guess View() still is the best multi-platform solution that I could find…
Yes, I sometimes use Excel to view data from R during a session. I recommend looking at this blog post on the Learning R blog. I use the RDCOMClient; it allows for more than just export/import, but the trade-off is added complexity.
Edit: There are several other solutions that are non-COM based in that blog post, including using ODBC.
