Re: [R] applying rbind to list elements
do.call("rbind", l)
or, in the case of matrices, using the abind package:
abind(l, along=1)
> library(abind)
> l <- list(matrix(1:6, ncol=2), matrix(11:14, ncol=2))
> abind(l, along=1)
[,1] [,2]
[1,]14
[2,]25
[3,]36
[4,] 11 13
[5,] 12 14

[R] applying rbind to list elements
Hi, I have a list of n data.frames (or matrices) which I would like to convert to a single data.frame using rbind: x <- rbind( l[[1]], l[[2]], l[[3]], l[[4]], ..., l[[n]] ) Is there a simple way to do this? thanks Hendrik -- Hendrik Fuß PhD student Systems Biology Research Group University of Ulster, School of Biomedical Sciences Cromore Road, Coleraine, BT52 1SA, Northern Ireland __ R-help@stat.math.ethz.ch 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.
