Hey there,
I've got a for loop in my code which I'm having difficulty seeing how to
avoid.
Here's the code, with some sample data. You can safely copy and paste into
the interpreter if you want.
#I have some data frames.
a <- as.data.frame(matrix(runif(50), nrow = 10, ncol = 5))
b <- as.data.fra

I hope it helps.

I'm trying to build up a list of data.frames by "appending" one by one.
If x,y,z are data.frames, I can do
somelist <- list(x, y, z) (or even somelist <- list(x=x, y=y, z=z) to get

somelist <- list(x,y) and now want to go from this to list(x,y,z) I'm stuck.
