Hi,
Suppose I have a logical vector x, I want to compute the 'and'
?all
and
'or'
?any
of all its element (the result should be a single value TRUE or
FALSE). I have read the R-intro.pdf logical vector section, but I
don't find the answer.
I couldn't find them either.
Can somebody let me know how to do it?
x= rep(TRUE, 3)

Peng
