Hi Andreas, Assuming you are using read.table(), try setting the argument: stringsAsFactors = FALSE
Also consider what about the Excel file is making R default to a factor rather than numerical? There may be a nonstandard reprsentation of missing data (e.g., "."), which could also be specified to read.table() For more info, see the documentation for ?read.table HTH, Josh On Fri, Mar 11, 2011 at 7:45 AM, Andreas Emanuelsson <andreas.emanuels...@sik.se> wrote: > Hi, I have tried to load a file originally from Excel, via csv, text and > clipboard today. > > When I succeed I cannot change the format from "factor", and when I try to > convert it to numerical it only gives the position of the "factor-group", not > the real value in the column? > > Any quick suggestions? > > Andreas > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > -- Joshua Wiley Ph.D. Student, Health Psychology University of California, Los Angeles http://www.joshuawiley.com/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
