Re: [R] R does not subset

This typically occurs because of sloppy manual data entry outside of R. To relieve further analysis pain, you can manually clean the data (usually only effective for one-time analyses) or use R to fix problems right after loading the data (there are multiple methods for doing this... I prefer usin

Re: [R] R does not subset

Jorge, thanks for your suggestions, but they give the same (empty) result: > RECinf<-subset(REC2, INFECTION=="Infected") > head(RECinf) [1] RINGNOyear ccFLEDGE rec2012 binageINFECTION all.rsLD <0 rows> (or 0-length row.names) but David's suggestion worked! : > RECinf<-REC2[REC2$

Re: [R] R does not subset

Hi Kasia, You need subset(REC2, INFECTION=="Infected ") (note the space after "Infected"). HTH, Jorge.- On Fri, May 3, 2013 at 7:48 PM, Katarzyna Kulma wrote: > Hi everyone, > > I know there have been several requests regarding subsetting before, but > none of them really helps with my prob

Hi Luis, thanks for the suggestion, but still nothing: > RECinf2<-subset(REC2, INFECTION==1) > head(RECinf2) [1] RINGNOyear ccFLEDGE rec2012 binageINFECTION all.rsLD <0 rows> (or 0-length row.names) cheers, Kasia Katarzyna Kulma PhD Student Department of Ecology and Genetics

Re: [R] R does not subset

You have an extra space in the INFECTION factors. Use REC2[REC2$INFECTION=="Infected ",] or subset(REC2, INFECTION=="Infected ") No need to use which here. On May 3, 2013, at 5:48 AM, Katarzyna Kulma wrote: > Hi everyone, > > I know there have been several requests regarding subsetting before,

[R] R does not subset

Hi everyone, I know there have been several requests regarding subsetting before, but none of them really helps with my problem: I'm trying to subset only infected individuals from the REC2 data.frame: > str(REC2) 'data.frame':362 obs. of 7 variables: $ RINGNO : Factor w/ 370 levels "BL1
