Hi folks, I KNOW there has to be a way to do this more elegantly, but I consistently fail to come up with it, as I was just reminded while writing an example for a query on this list.
What's a nifty way to construct a data frame of a given size? The only way I know of it to use matrix(), eg data.frame(matrix(NA, nrow=10, ncol=3)) and then to set the colnames in a second step. This comes up a lot when pre-allocated a data frame before using a loop: I know the size and column names, but want an empty structure to fill later.
