Hello, it might be a very simple question but I cannot find the solution (I tried a || b, any(a,b)... but none works). My problem is: I have two vectors, a <- c(TRUE,FALSE,FALSE) b <- c(TRUE,FALSE,TRUE) and I would like to obtain a vector that indicates if it is TRUE in any of the two vectors. Hence, the desired output would be: TRUE, FALSE, TRUE Thank you in advance, Federico __________________________________________________ [[alternative HTML version deleted]]
I think I found the solution (just after sending the email). The following apparentely works: a == TRUE | b ==TRUE Regards, Federico Federico Abascal <fede_rgroup@yahoo.com> escribió: Hello, it might be a very simple question but I cannot find the solution (I tried a || b, any(a,b)... but none works).

Or you can use the "&" operator:> a <- c(TRUE,FALSE,FALSE) > b <- c(TRUE,FALSE,TRUE) > a & b[1] TRUE FALSE FALSE On 5/4/07, Federico Abascal <fede_rgroup at yahoo.com> wrote:> Hello, > > it might be a very simple question but I cannot find the solution (I tried a || b, any(a,b)... but none works).
