convert dataframe to new list

Question

I have a data.frame NOAA_OLR_TEST

NOAA_OLR_TEST <- structure(list(DATE_START = structure(c(1170720000, 1170806400,
1170892800, 1170979200, 1171065600, 1171152         


        

Answer 1

You can do this with data.table:

library(data.table)
setDT(NOAA_OLR_TEST)
NOAA_OLR_TEST[,xy.list:=list(OLR_DATA_1,OLR_DATA_2,OLR_DATA_3,OLR_DATA_4,OLR_DATA_5)]
NOAA_OLR_TEST[,(5:9):= NULL]

is.list(NOAA_OLR_TEST$xy.list)
[1] TRUE
