[R] legend title in qplot

[RON70]

Thank you for your reply. Yes I am reading that document and ofcourse
simultaniously trying to apply in my current problem as well. Yes still I am
learning.

Here I have my code :

library(ggplot2)
library(plyr)
dat = rnorm(1000); variable = rep(c("Variable:1", "Variable:2"), each=500);
coll = rep(c("10", "20"), each=500); dat1 = data.frame(dat, variable, coll);
dat1
p = ggplot(dat1) + geom_line(aes(y=dat, x=1:500, colour=coll),
group=variable) +  facet_grid(variable ~ .); p 
#p + scale_colour_hue(h = c(0, 90), l=70, c=30)

Here I have not used scale_colour_hue() function because I fill I have very
little control over the colors at least for my current problem. Therefore I
have created a new variable "coll" and put the numbers for that variable,
which best match my desired color.

However here my problem is in color pallet, values of "coll" is displayed,
not values of "variable". But this problem can be solved if I use
scale_colour_hue(). Can anyone please suggest how to show the values of
"variable" in pallet correctly?
