Hello Group,

Is there a simpler way to get data out of a list object? (like in data frame without using the apply functions)

I have the following dataset

> dput(d)

list(c("20110405", "092102"), c("20110405", "092538"), c("20110405", "093458"), c("20110405", "101124"), c("20110405", "102041"),

    c("20110405", "103659"))

I extracted my data like this:

getDate <- function(x)(unlist(x[[1]]))

unlist(lapply(d, getDate))
[1] "20110405" "20110405" "20110405" "20110405" "20110405" "20110405"

Isn't there an easier way to do this?
