Hi,
This should work:
select <- l[which(l==x):which(l==y)]
The problem is that you tried to select the values, but gave x and y as
indexes. That's why you didn't get the expected result.
See ?which for more info.
HTH,

Dear group,
Here is a list :
l<-
list("100415", "100416", "100419", "100420", "100421", "100422",
"100423", "100426", "100427", "100428", "100429", "100430",
"100503", "100504", "100505", "100506", "100507", "100510",
"100511", "100512", "100513")
I need to access part of it with two variables, x and y. For example, if
x<-100415 et y<-100420, the result I want is 100415,100416,100419,100420.
The object "l" is a list, but can be of any other kind if it can help.
I tried something like this :
select<-l[c(x:y)]
But it doesn't return the needed result
Any help would be appreciated
