Emulate split() with dplyr group_by: return a list of data frames

Question

I have a large dataset that chokes split() in R. I am able to use dplyr group_by (which is a preferred way anyway) but I am unable to persist the r

Answer 1

To 'stick' to dplyr, you can also use plyr instead of split:

library(plyr)

dlply(df, "V1", identity)
#$a
#  V1 V2 V3
#1  a  1  2
#2  a  2  3

#$b
#  V1 V2 V3
#1  b  3  4
#2  b  4  2

#$c
#  V1 V2 V3
#1  c  5  2
