Dear R gurus,
first let me apologize for a question that might hve been answered before. I was not able to find the solution yet. I want to concatenate two lists of lists at their lowest level. Suppose I have two lists of lists: list.1 <- list("I"=list("A"=c("a", "b", "c"), "B"=c("d", "e", "f")), "II"=list("A"=c("g", "h", "i"), "B"=c("j", "k", "l"))) list.2 <- list("I"=list("A"=c("A", "B", "C"), "B"=c("D", "E", "F")), "II"=list("A"=c("G", "H", "I"), "B"=c("J", "K", "L"))) > list.1 $I $I$A [1] "a" "b" "c" $I$B [1] "d" "e" "f" $II $II$A [1] "g" "h" "i" $II$B [1] "j" "k" "l" > list.2 $I $I$A [1] "A" "B" "C" $I$B [1] "D" "E" "F" $II $II$A [1] "G" "H" "I" $II$B [1] "J" "K" "L" Now I want to concatenate list elements of the lowest levels, so the result looks like this: $I $I$A [1] "a" "b" "c" "A" "B" "C" $I$B [1] "d" "e" "f" "D" "E" "F" $II $II$A [1] "g" "h" "i" "G" "H" "I" $II$B [1] "j" "k" "l" "J" "K" "L" Has anybody a good solution for that?
