I think it because you are trying to use the if-else control
construct, when you should be using the ifelse function:
?ifelse
Try (perhaps):
traindev <- ifelse( (trainlength>0), round(sd(trainscores, na.rm=T),
1) , "")
You do seem to be mixing types, though, so perhaps you should use NA
instead of "".

I hope someone can point out my stupid error, because I'm baffled.
I am calculating a bunch of variable values and then placing them in a
document using odfWeave tags.
This is working very nicely for every spot except one.
One of the values I calculate is traindev:
traindev <- if (trainlength>0) round(sd(trainscores, na.rm=T),1)
else ""
when I try to insert this traindev value anywhere in my odfWeave
document
(using \Sexpr{traindev} ), I get the following error:
Start tag expected, '<' not found
Error: 1: Start tag expected, '<' not found
Another formula,
postsd<- if (postlength>0) round(sd(postscores, na.rm=T),1) else ""
does not trigger the same error.
It's not something strange with the variable name; give any other
value to
that variable and odfWeave works just fine. It's not the spot on the
document; any other tag works great in that spot and but traindev
triggers
the error wherever I try to put it.
I've spent a horrendously long time trying to figure it out. Can
anyone help
me out?
R version is 2.7.1
odfWeave is whatever the latest version is
os is Mac OS10.5.5
