Hi,
Is there a way to create a treemap with more than 1 grouping. I've seen a
lot of examples like this:
http://flowingdata.com/2010/02/11/an-easy-way-to-make-a-treemap/ but what if
some of my categories have sub-categories. Is there an existing function
that can handle this
thanks

Hi,
I'm having trouble editing the qplot layout. I'm using the geom=tile
option and I want to do a few things:
1. move the vertical and horizontal gridlines so that they appear on the
edge of each tile (right now they're in the middle)
2. bring the gridlines to the foreground and change their
Hi,
Is it possible to create a heatmap for say a 3x3 matrix of data where every
color is pre-assigned?
I can easily create a matrix of hex colors but when I try to use that matrix
as the parameter for the 'col' option it doesn't work. If it's possible to
just display a matrix of hex colors that
Hi,
I'm trying to create a heatmap with color ranges for different values in my
matrix. For example:
If x 5 , use orange gradient
if x 1.5, use red gradient
.
Right now I have the following:
orgPal-brewer.pal(3,Oranges)
bluPal-brewer.pal(3,Blues)
redPal-brewer.pal(3,Reds)
grad -
as a followup, I tried using the rainbow function to create the gradients but
is there a way to do a reverse rainbow, ie. normally if I do:
pie(rep(1,6), col=rainbow(6,start=0, end=.07))
I'll get a gradient from dark red to orangish but what if I want it to go
the other way
thanks

thanks,
I think I got the color ranges down, however, I just realized that the
colors don't match the data. When I execute:
grad - ifelse(randMat 5,yelPal,ifelse(randMat1.5,redPal,bluPal))
the grad matrix contains the correct hex codes corresponding to the randMat
data matrix but when I
also, can you point me to some example of how to omit colors from a palette
