Dear
R-users,
I've been trying to write a script but i encounter much problems with basic
functions.. That is, i try to write a simple IF ELSE statement, with 2
requirements for the IF :
if (abs(x + Dataset$LAT[1]) <= 3) and (abs(y + Dataset$LONG[1]) <= 3) {z
<- 1} else {z <-0}
This does not work. So far i succeeded with one of tthe conditions :
if (abs(x + Dataset$LAT[1]) <= 3) {z <- 1} else {z <-0}
> this work, so i tried to had the second condition with "and" or
"&" or even "& &&" as writen in operators
r-help but none of my trials works, it retrun "unexpected symbol
"{" ...
any tip ?
with regards
