Can't remove legend

[Stuart Luppescu]

Hello all, I'm trying to completely remove the legend in my plot but I'm
failing. I have this code:

ggplot(acno, aes(x=survey_year, y=item_displ, color=as.factor(item_id)))
+
geom_line() +
theme(legend.position="none")

The last line gives this message:
Error: ggplot2 doesn't know how to deal with data of class uneval

I have also tried:
scale_color_discrete(guide=FALSE)
and
guides(color=FALSE)
but they all give the same error. Anyone have a clue?

TIA.

Never mind. I was just being stupid. It was something unrelated.

The problem isn't with the " theme(legend.position='none')" line,
which is correct. Something else is going on. I would suggest first
building your base plot and assigning it to a variable, and verify
that it renders correctly. Then remove the legend. For example

p <- ggplot( ... )
print( p )
print( p + theme(legend.position="none") )
