That dreaded floating point trap
Hi,
I had a piece of code which looped over a decimal vector like this:
for( i in where ){
thisdata <- subset(herde, herde$mlr >= i)
# do stuff with thisdata..
}
'where' is a vector like seq(-1, 1, by=0.1)
My problem was: 'nrow(thisdata)' in loop repetition 0.4 was different if
'where' was seq(-1, 1, by=0.1) than when 'where' was seq(-0.8, 1, by=0.1)
It...

Problem building up ggplot graph in a loop.
Folks,
I want to automate some graphing using ggplot.
Here is my code
graphChargeOffs2<-function(coffs) {
ggplot(coffs, aes(levels))
dataNames<-names(coffs)[!names(coffs) == "levels"]
for(i in dataNames) {
thisData<-coffs[[i]]
last_plot() + geom_line(aes(y = thisData, colour = i))
}
last_plot() + ylab("Total Chargeoffs")
}
coffs is a data.frame.
I get the following error:
Error in eval(expr, envir, enclos) : object 'thisData' not found
As little as I know about environments in...

Lattice/"panel.bwplot" and Gviz: Boxplot question
Hi,
I was using Gviz package to create a boxplot. I understand that Gviz uses
"panel.bwplot" to create the boxplot.
Is there any way that I can remove the dashed line surrounding each pair of
boxplots?
Here is some sample code:
#############
library(Gviz)
thisdata <- matrix(sample(1:100,60),nrow=10,ncol=6)
positions <- sample(1:100,6)
limit1 <- min(positions)-1
limit2 <- max(positions)+1
colnames(thisdata) <- positions
dgroups <- c(rep('sample1',6),rep('sample2',4))
chr <- "chr1"
d4x <- DataTrack(start=posi...
