I am trying to learn R and understand how a symbol works &. I understand that this means "and."
&
When am I trying to 3 < (5 & 4)get it FALSE? I was expecting TRUE. Am I using the &wrong way?
3 < (5 & 4)
FALSE
TRUE
In R TRUE, the number 1in your arithmetic expression is evaluated , therefore:
1
3 < (5 & 4) 3 < TRUE 3 < 1
which is equal FALSE
You can verify that R treats TRUEas the 1following code snippet:
> x <- c(-3:3) > x [1] -3 -2 -1 0 1 2 3 > x == TRUE [1] FALSE FALSE FALSE FALSE TRUE FALSE FALSE
, , , : " 3 5 4?". , 3 < (5 & 4). , R , (5 4), , , 3 TRUE. , - :
(3 < 4) & (3 < 5)
:
all(3 < c(4,5))
Try using:
3 < c(4,5)
Thus, it will be tested for both 4 and 5.

TRUE TRUE
