I can't debug this because you haven't said what
levels2weeklyret() does. However, I can offer a tip:
use traceback() straight after the error to see exactly
where it goes wrong. If still baffled, use debug() [takes
a bit of learning].
To return multiple values, return a list (see ?return) or
Issue the command:
debug(eat.a.file)
and then run your eat.a.file call. This will step you through
the function showing where it goes wrong.
By the way,
- you don't need semicolons at the end of each line,
- the format you are specifying on chron is the default anyways
so you can leave
Folks,
I have the following repetitive code which works correctly:
A = read.table(file=junior.csv, sep=,, col.names=c(date, l));
A$date = chron(as.character(A$date), format=m/d/y);
r.junior = levels2weeklyret(lastfriday, A$date, A$l);
plot(A$date, A$l, type=l, col=red, main=Junior
