How to split a Dataframe According to a variable?

If you want to split a dataframe according to values of some variable, I’d suggest using daply() from the plyr package. library(plyr) x <- daply(df, .(splitting_variable), function(x)return(x)) Now, x is an array of dataframes. To access one of the dataframes, you can index it with the name of the level of the splitting variable.
