Hi,
I'm quite new using R and have got no one to help me get through it.
Hopefully someone can help me with one problem I've been struggling with
for the last hours!!
(Sorry if I'm using the wrong terminology as well!)
I have a data matrix in which SIE is one of my variables. What I need to
do now is to create a new variable (group) if a certain condition in SIE
is met.
I tried:
if (data2$SIE < 50.646){
data2$group=as.factor("small")
}
which gives me "In if (data2$SIE < 50.646) { : the condition has length
> 1 and only the first element will be used"
and
ifelse (data2$SIE < 50.64593, data2$group =
as.factor("small"),data2$group = as.factor("large"))
with "Error: unexpected '=' in "ifelse (data2$SIE < 50.64593, data2$group ="
I tried all other kinds of variations and so far, nothing!!
Is there a good way to do this that someone could teach me?
Thank you so much,
Vitória
