ifelse problem - bug or operator error
Hi Michael, Thanks for letting me know how to post data. I will try to upload it that way in a second. I can usually use code to make a reproducible dataset but this time with the ifelse behaving strangely (perhaps, it's probably me) I didn't think I could do it easily so I figured I would just put my data up. I will check out the R FAQ you mentioned. Thanks, again, Jen On Fri, Aug 24, 2012 at 5:50 PM, R. Michael Weylandt

Hi Michael, No, I never use attach(), exactly for the reasons you state. To do due diligence I did a search of code for the function and it didn't come up (I would have been shocked because I never us it!). Now that real data is up, does your suggestion still apply? I am reading it now.
If you mean the data you sent to Peter, it got scrubbed by the list servers as well (they are somewhat draconian, but appropriately so in the long run). The absolute best way to send R data via email (esp on this list) is to use the dput() function which will create a plain text representation of your data _exactly_ as R sees it. It's a little hard for the untrained eye to parse (I can usually get about 90% of what it all means but there's some stuff with rownames = NA I've never looked into) but it's perfectly reproducible to a different R session. Then us having the same data is a simple copy+paste away. For more on dput() and reproducibility generally, see http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example It could be the floating point thing (it's hard to say without knowing how your data was calculated), but Rui seems to think not.

Off the wall / wild guess, do you use attach() frequently? Not entirely sure how it would come up, but it tends to make weird errors like this occur. M On Fri, Aug 24, 2012 at 4:36 PM, Jennifer Sabatier <plessthanpointohfive at gmail.com> wrote:
Hi Rui, Thanks so much for responding but I think with my HTML problem the vn data you made must not be the same. I tried running your code on the data (I uploaded a copy) and I got the same thing I had before. Jen On Fri, Aug 24, 2012 at 5:28 PM, Rui Barradas <ruipbarradas at sapo.pt> wrote:
