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") barplot(x, names=mynames, las=2, col=mycols) legend(2,20,legend=c("A","B","C","D"),fill=mycols) ### 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. these
