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

If, like me, you are mostly looking to create lists of lists to use in highcharter, that same package contains the function list_parse() (or list_parse2() if you want to remove names). Simply use it like so:

library(highcharter)

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

LoL <- list_parse(df)

After which you can do the indexing you wanted:

> LoL[[1]]$start
[1] 100
