Hello,
I want to do some simple bar plots on email arrival data, but I do not quite
get the point how to remove the legend. I use the following code:
> dow <-
read.csv(file="j:/uni_lernen/da_stockspam/svn/data/c411_weekday.txt",
header=TRUE)
> dow$dayofweek <- factor(dow$dayofweek)
> days <- c("Sun", "Mon", "Tue", "Wed","Thu", "Fri", "Sat")
> levels(dow$dayofweek) <- days
> dow
dayofweek c p w
1 Sun 16477 0.1333 0
2 Mon 19384 0.1568 1
3 Tue 18638 0.1507 1
4 Wed 19747 0.1597 1
5 Thu 20709 0.1675 1
6 Fri 16412 0.1327 1
7 Sat 12283 0.0993 0
> qplot(dayofweek, p, data=dow, geom="bar", xlab="Day", ylab="Arrival Rate",
main="Spam by Weekday", fill=w)
The idea of the w parameter is to give weekends a different color. But when
I do this, I always get a legend of "w" with two entries for its two colors.
How can I avoid this?
Thanks and regards,
Christoph
