plot 8 functions on one graph?

I'm trying to use
ggplot to make a single graph
that plots 8 distributions,
one above the other.

I created a data.frame
with 9 rows.   The first
is the coordinate along the x-axis.
The next is the y-values for
the first distribution.
After that is the y-values
for the next distribution... and so on.

How do I call ggplot to use such a data.frame
to make a single graph of 8 distributions?

Should my data.frame be formed differently?

Hi

Normally data in data frames are considered column wise and ggplot expects this

ggplot(yourdataframe, aes(x=some column, y=other column, colour=grouping factor, ...)

So if you want to use ggplot, you shall transpose your data frame and reshape it to long format.

See
?ggplot
?t
?reshape
?melt

BTW, although there was no problem with your HTML formated mail it is preferable to use plain text mail in this list.
