Category: User Education Group: None >Status: Closed Resolution: Invalid Priority: 1 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Gregory Warnes (warnes) >Summary: RPy misinterprets \"< 2.2e-16\" as \"-2.2e-16\" Initial Comment: Interestingly, I reported this a few days ago and it has disappeared. The basic problem is that ks.test() returns the p-value "< 2.2e-16" and RPy converts this in -2.2e-16 sometimes, and sometimes to 0.0. It's hrd to say what it should return, but returning a negative value is certainly incorrect. Probably +2.2e-16 would be the best choice. This was using RPy version 0.4.6 and R version 2.2.1. My earlier post was cluttered with other information which upon further investigation I found was not relevant. I apologize if this is not the correct way to post bugs. If not, please contact me at the 31031em at gmail.com, after reversing the order of the letters to the left of the @. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2006-10-30 21:33 Message: Logged In: NO I was not able to figure out how to look at the closed error report so I reposted.

See https://sourceforge.net/tracker/index.php?func=detail&aid=1585977&group_id=48422&atid=453021 to read why it isn't a problem with RPy. Short summary: the actual value in the R object *is* negative. The R object printing code converts it for *printing* to 'less than ...'. Since you are writing code that accesses the contents of the object directly, you will need to write wrapper code to handle negative values appropriately. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=453021&aid=1587588&group_id=48422 ------------------------------------------------------------------------- Take Surveys.
