Re: [R] Swap variables in data.frame

Thanks might be easier in my case because I have so many variables. Could have found this solution on my own. Birgit Rogers, James A [PGRD Groton] wrote: Birgit Lemcke wrote: I have a dataframe and two of my variables are in the wrong position and I would like to swap those

Re: [R] Swap variables in data.frame

Thanks but it swaps in both cases only the data: FemMal_88[c(61,62)]=FemMal_88[c(62,61)] FemMal_88[,c(61,62)]=FemMal_88[,c(62,61)] Greets B. Karl Ove Hufthammer-4 wrote: Birgit Lemcke: I have a dataframe and two of my variables are in the wrong position and I would like to swap

[R] Swap variables in data.frame

Hello R-user community! I am running R 2.7.0 on a Power Book (Tiger). (I am still R and statistics beginner) I have a problem that is certainly solved very easily but presently I don`t know how. I have a dataframe and two of my variables are in the wrong position and I would like to

Re: [R] Swap variables in data.frame

Birgit Lemcke: I have a dataframe and two of my variables are in the wrong position and I would like to swap those variables. To swap column 1 and 2, try d[c(1,2)]=d[c(2,1)] Note that this is different from d[,c(1,2)]=d[,c(2,1)] which will swap the data, but not the column names. --

Re: [R] Swap variables in data.frame

Thanks Paul. I am not sure if I understood well, but when I do it then I have only two columns left: L3 - LETTERS[1:3] (d - data.frame(cbind(x=1, y=1:10, z=11:20), fac=sample(L3, 10, replace=TRUE))) x y z fac 1 1 1 11 C 2 1 2 12 B 3 1 3 13 B 4 1 4 14 C 5 1 5 15 C 6
