Combine dataframe from two list to a single list

Question

I have two lists containing multiple dataframes listA and listB . The first list has 5 dataframe, and the second list has 3 dataframe. I want to form a third list listC where it contains the dataframes from both list such that I will have 8 dataframes in total in listC . I tried using merge() , but it didn't seem to work.

Answer 1

The function to use is append() :

df <- data.frame(v1 = c(1,2))

l1 <- list(df, df, df, df)
l2 <- list(df, df)
l3 <- append(l1, l2)
