optmizing with monotone stepfunctions?
Before re-inventing the wheel I would like to ask: does anyone know about
an optimizer in R which can reliably identify which value of X (Xopt) leads
to Y (Yopt) closest to Ytarget in
Y <- MonotoneStepFun(X)
optionally with the restriction that Yopt <= Ytarget
(at least if any Y <= Ytarget, otherwise any Yopt > Ytarget would be the
preferred answer)
If none is known, I will write

Question about barplot: gridlines & value labels
Hello!
I promise I looked into help files before asking. Still cannot figure
it out. I think it's because I am totally confused what packages use
lettice, which use trellis, etc.
Sections 1 and 2 below produce the data and the data to plot. My
question is about barplot in Section 3. I am trying to:
1. add only horizontal gridlines and manipulate the type and color of
that line. tck = 1 is not

Working up examples of barplots with customized marginal items
...he default colors are so dark. You can't write on top
### of them. You can grab shades of gray like "gray30" or such.
### I'll just specify 4 colors I know will work. I prefer
### the light gray colors because they can be written over.
mycols <- c("lightgray","gray70","gray80","gray90","gray75")

### Still, I don't like the solid shades so much.
### fill up the bars with angled lines.

Matrix heatmap
I would like to organize my data as follows:
I have a table that contains various data, and the numbers represent a level
of similarity between these data,
eg RF00013 has 100% similarity with the data RF00014.
I would leave my table as a heatmap where darker colors represent higher
similarity, and the lighter colors represent less level of similarity.
I'm using version 2.11 of R.
