Subject: [R] Named list of data.frames to data.frame with names
Hi,

Hello,
You're right, sorry for the misleading post. It's even documented:
"|times||A |integer vector giving the (non-negative) number of times to
repeat each element if of length |length(x)|"
As for a one liner, use within().
within(do.call(rbind, l), name <- rep(names(l), times=sapply(l, nrow
Hello,
There's nothing inelegant in your solution, you're using vectorized
instructions.
But there's a bug. The argument to rep should be 'each', not 'times'.
l2$name <- rep(names(l), each=sapply(l,nrow))
Hope this helps,

Hi,
I very frequently end up in a situation where I have a named list of
data.frames that I wish to combine. e.g.
l <- list(A=data.frame(x=rnorm(5),
y=rnorm(5)),
B=data.frame(x=rnorm(3),y=rnorm(3)),
C=data.frame(x=rnorm(4),y=rnorm(4)),
D=data.frame(x=rnorm(7),y=rnorm
4 matches
