Combining lists of different lengths into data frame

Question

I have data like the SampleData below, which has lists of different length that I\'d like to combine in to a data frame like the Desired Result below. I\'ve tried using lap

Answer 1

Here is a modified version with length<- assignment

setNames(do.call(cbind.data.frame, lapply(lapply(SampleData, unlist), 
        `length<-`, max(lengths(SampleData)))), paste0("V", 1:3))
#  V1 V2 V3
#1  1  1  3
#2  2  2  4
#3  3 NA  6
#4 NA NA  7
