i think i asked the wrong ?

Dear Jimi,

me again, new to R, haven't programmed in a long time at all
sorry to ask what is probably basic

a while ago i asked how to remove an element from a list
apparently what i am using is not a list but a vector, didn't realize 
there was a list data type
could also use a matrix for what i am doing, is there a way to remove 
single elements from either of those?

thanks for any help, if i was actually using a list as i said last time, 
the answers i received would have cleared things right up

You can use negative indices to remove entries from a vector; for example,

 > v <- 1:10
 > v[-5]
[1]  1  2  3  4  6  7  8  9 10
 > v[-c(3,6)]
[1]  1  2  4  5  7  8  9 10

Removing single elements from a matrix doesn't make sense -- what goes in 
the hole? You can, however, remove entire rows or columns with negative 
indices.

(Indexing is discussed in all of the basic introductions to R and S of 
which I'm aware. It probably makes sense to read one of these -- you'll 
save time in the long run.)

I hope that this helps,
  John
