Hi:
here is one solution. Not so elegant but maybe it will give you some ideas:
mylist1<-rep(mylist,c(2,2))
a<-matrix(c(index1,!index1,index2,!index2),ncol=4)
mylist2<-list()
for (i in 1:4)
{
mylist2[[i]]<-mylist1[[i]][,a[,i]]
}
mylist2

Dear List,
Let's say I have a list whose components are 2 matrices (as exemplified in
the "mylist" object below). I'd like to create a list with components being
4 matrices based on an logical index vector. is there a way to simplify what
I'm doing to obtain the results in "mylist2"? I'd like some
2 matches
