title: Combine two lists in R into a dataframe
body: <p>I have two lists in R of identical length and would like to combine them into a data frame with the total number of rows in the resulting data frame equivalent to the length of the two lists (in other words, each list is a column). When I tried using <code>c(list1, list2)</code> the two lists were appended together and when I used <code>cbind(list1, list2)</code> the total number of observations was almost double the original length.</p>
