I have a list of vectors, x, with x[[1]]=1:5, say. And I need to go through each element of each vector in a for loop. Something like:
for (v in x[[1]]) print(v) However, I need to store this index "v" for later, and I have lots of other indices which we range over later in the code so thought I'd make a list of these indices, v<-list(). But then when I try: for( v[[1]] in x[[1]] ) print(v[[1]]) I get errors: > x<-list() > x[[1]]=1:5 > v<-list() > for(v[[1]] in x[[1]]) Error: unexpected '[[' in "for(v[[" > print v[[1]] Error: unexpected symbol in "print v" Can you not use a list in this way, i.e. to store variables to range over in a for loop? Can anyone offer a solution?
