Hi, I have a data frame where 1 variable is a factor with only 1 level. I need the data frame structure to reflect that there are 2 levels for this factor, even though this is not the case. I am currently adding extra 'fake' rows to the data frame to ensure that 2 levels are present, but this is slowing processing time in a loop quite a bit. Can I manually specify that this factor variable has two levels (even though this is lying to R)? Thanks,Seth -- View this message in context: http://r.789695.n4.nabble.com/better-way-to-trick-data-frame-structure-tp2130470p2130470.html Sent from the R help mailing list archive at Nabble.com.
