mapping of colornames into hsv: half way done
Ok,
now we have the mapping of color names to color codes (see below) and
conversion to rgb (something like Ben Bolker's function), but how to convert
rgb to hsv?
Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker

heatmap.2 with colsep and sepwidth
I am using attributes colsep and sepwidth from heatmap.2 function,
however when using larger values for sepwidth the following columns are
not moved to the right but the seperator is covering the column(s) with
a white bar and the column labels and ColSideColors remain at their
positions, is this intended? I expected the following columns to be
shifted to the right by sepwidth. Is there a way

I managed to do it with the following code but not know how to make a function of these so that next time if I want to do similar graph but with new variables, I dont have to copy the code and then change the old variables with the new ones but just call a function with the new

ggplot qplot bar removing bars when truncating scale
I'm having problems with this example, it is posted with reproduceable code
below, both with the normal 0-6 scale and the desired 3-6 scale (with bars
removed). How can I get the graph to have the desired 3-6 scale without
removing the bars. Thanks!

adding color bar to a graph
Hi everybody,
I am wondering how i can add a "stretch" color bar / legend to a graph that uses colorBrewer to define the colors in it. I will try to explain my graph, but i also uploaded it at: ftp://ftpext.usgs.gov/pub/er/fl/st.petersburg/Monica_pal/
The file is: robcor_training_pca.pdf - i will also attach this file in case some people accept attachments.

Transparent Labels for Polar Plot
Hello,
I am currently using the polar.plot function in the plotrix package to graph data. Unfortunately, it seems that the default for the labels is to have a background color that is covering the line representing my data, making it difficult to read. Is there a way to make this label background transparent?
Example:
lengths <- 0:72
bearing <- seq(from=0, to=360, by=5)

Secondary Y axis title
I have the following R code to create a plot with two y axes. I am
essentially trying to
plot a price series with a volume series on the same graph. (i.e. to
compare price with volume). I can label the first
y axis successfully, but the problem is in labeling the 2nd y-axis.
Essentially, the
label never appears. It seems as though there is not enough margin

levelplot border and dendrogram width
Hello,
I'm trying to learn how to use lattice and levelplot in particular.
There are three elements of customizing the plots I'm stuck with:
a) Is there a way to put borders around each "cell" within a
level-plot. I'm trying to do something like the
colsep/rowsep/sepcolor/sepwidth parameters of heatmap.2 in gplots
b) Can I alter the line-width of dendrogram added

problem with heatmap.2 in package gplots generating non-finite breaks
I have written a wrapper for heatmap.2 called
heatmap.w.row.and.col.clust which auto-generates breaks using
breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20,
digits = 2) #(stddev in this case = 2.5)
This has always worked well in the past but now I am getting an error
that non-finite breaks are being generated. Drilling down, it seems
