split dataframe by row number in R

Question

This is probably really simple, but I can\'t find a solution:

df <- data.frame(replicate(10,sample(0:1,10,rep=TRUE)))

v <- c(3, 7)

i

Answer 1

Another way:

split(df, findInterval(1:nrow(df), v))

For the alternative interpretation, you can use:

split(df, cut(1:nrow(df), unique(c(1, v, nrow(df))), include.lowest=TRUE))
