R help - Aug 2011 - How to extract sublist from a list?

Hi everyone,

Suppose I have a list named "lst", see below:
> lst
$sub1
...
$sub1$x
...
$sub1$y
....

$sub2
...
$sub2$x
...
$sub2$y
?
$sub3
...
...
...

Now, I want to extract the sub-sublist $y from every sublist(sub1, sub2...)
and then storage them to a new list.

I know how to extract them by subscript or list name one by one, but I
wonder if there exist some tricks to finish this job more automatically. 

Best regards,
Richard @Sydney

Thank you so much GlenB!

I got it done using your method.

I'm just curious how did you get this idea? Cause for me, this looks so
tricky....

Cheers,
Richard

Hi, have you considered using array, 
for example 
example<-array(1,dim=c(2,2,3))
dimnames(example)<-list(c("x1","x2"),c("y1","y2"))
then if you want to extract the component "x1","y1" from
every member of the
list of matrices you have to
example["x1","y1",]
leaving blank in the last position. 
hope it helps.
Victor
