Subject: [R] Using If loop in R how
hi,
Can someone please help me figure out where I am making a mistake in my for/if
loop:
I have a data frame (112 rows) called pricedata with 3 columns: date, prices,
return.
Now, I want to add a 4th column, trend, which can have 2 values 0 or 1. if
return1%, trend=1 else trend=0.
so, this
For me, this works:
Now, I want to add a 4th column, trend
pricedata$trend - 0
which can have 2 values 0 or 1. if return1%, trend=1 else trend=0.
pricedata$trend - ifelse( pricedata$return .01, 1, 0 )
Rgds,
Rainer

PLEASE do read the posting guide http://www.R-project.org
The break command can only break the innermost loop (the b loop in your
case). Rewrite the loop control logic. Here is one example
end.a - FALSE;
for (a in 1:10) {
print(a);
for (b in 1:20) {
if (a 5 b 5 ) {
end.a - TRUE;
break; # Breaks the b loop
}
};
Hi All,
I was wondering if there is anything that breaks a loop in R. For example,
For (k in 1:100)
For ( i in 1:10){
If ( condition ){
Break the inner loop
}
}
}
In the above case, if the program runs the if statement, then I want the
inner loop for (i in 1:10) to stop looping and skip

? `break`
