R help - Jan 2013 - Concatenate two lists, list by list

Dear all,
I would like to concatenate the lists below

str(Part2$dataset)
List of 3
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...



str(Part1$dataset)
List of 3
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...


I tried concatenating those with:

> str(cbind(Part1$datase,Part2$dataset))
List of 6
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:16001] 0 0 0 0 0 0 0 0 0 0 ...
 - attr(*, "dim")= int [1:2] 3 2


but I want something different. To concatenate those into  a list by list
operation so I will end up with something looking like that

str(concatenatedLists)

List of 3
 $ : num [1:32002] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:32002] 0 0 0 0 0 0 0 0 0 0 ...
 $ : num [1:32002] 0 0 0 0 0 0 0 0 0 0 ...
 - attr(*, "dim")= int [1:2] 3 2


Is there anything that can do that in R?

Hi

Maybe you could use mapply

mapply(c, Part1$dataset,Part2$dataset)
