Converting a data.frame to a list of lists

Question

How can I convert a data.frame

df <- data.frame(id=c(\"af1\", \"af2\"), start=c(100, 115), end=c(114,121))

To a list of lists

Answer 1

Using plyr , you can do this

dlply(df,.(id),c)

To avoid grouping by id , if there are multiple ( maybe you need to change column name , id is unique for me)

dlply(df,1,c)
