[R] How to remove index from list after split?

[Wayne.W.Jones at shell.com]

Not sure what you mean by "group index" but try: 

lapply(df.s,function(l){l$x})
or something like: 

do.call("rbind",df.s) 

to convert the result into a data.frame. 

Regards

Wayne

Subject: [R] How to remove index from list after split?


In the following example, how can I drop the group index from the list after
I perform a split?
n     <- 3
nn   <- 10
g     <- factor(round(n * runif(n * nn)))
x     <- rnorm(n * nn) + sqrt(as.numeric(g))
df    <- data.frame(g,x)
df.s <- split(df,g)

Thanks!
