Hi,
Are you trying to get columns 2 and 3 from TripsData in which case you
need to say TripsData[,2:3] ?

Dear list,
would anybody be able to tell me why the statement

Hi John,
Try pa + scale_colour_brewer() and
see ?scale_colour_brewer for options
Also see scale_colour_manual where you can use the values parameter to
choose your own colours.
Cheers,

Hi Ron,
I'm not sure why ylab doesn't work. Maybe a bug. I note the label
doesn't get removed with labs() either. However using
scale_y_continuous(name=) does remove the label.
For the legend, you are using a fill scale, not a colour scale i.e.
fill=factor(dat[,2]), not

You can use help to view the available help files with the package.

Hi John,
You can use
rm(object)
to delete a specific object from the current environment and then save
your workspace again without those objects
ls()
to see a list of objects could also be useful

Hi,
You can add extra levels using levels().
e.g.
test - data.frame(x=c(1,2,4,4), y=c(A, 1, 2, A))
levels(test$y) - c(levels(test$y), 'B')
levels(test$y)
[1] 1 2 A B
test[test$x==4,]$y-'B'
test
x y
1 1 A
2 2 1
3 4 B
4 4 B

The problem is that the label on the graph doesn't get rendered with a

Hi,
If R is compiled for a 64 bit platform, does the double data type make
use of the additional precision or is it set at a fixed length?
Thanks,

I also use the approach Philipp describes below. I use Python and shell
scripts for processing thousands of input files and getting all the data
into one tidy csv table. From that point onwards it's R all the way
(often with the reshape package).

Hi,
With ggplot2 v0.8, how do I position a legend on top of the plot. Things
like
p + opts(legend.position=top)
work ok. But
p + opts(legend.position=c(0.5,0.5))

Hi,
I want to remove minor-horizontal and minor-vertical lines from a plot
generated with ggplot2. I can do this after the plot has been drawn
using grid.gremove.
However, I would like to do it before drawing my plot. The ggplot2 book
refers to a ggplotGrob function which creates a grob
in terms.formula(fmapply(fm, identity)) :
invalid term in model formula
Could someone put me in the right direction of how to correctly write a
