Only thing that when I put na.rm=FALSE, R is puting in v4 NA (as is largest) and I want to see NA as zero (0, smallest value) 2010/4/22 Vlatka Matkovic Puljic > Thanx a lot! That's it! > > 2010/4/22 Duncan Murdoch > > On 22/04/2010 11:07 AM, Vlatka Matkovic Puljic wrote: >> >>> Hi! >>> >>> I h

Hi all, I would like to get the array index for a range of values, say 0 < x < 1.5. I'm wondering if there is an alternative for the following which I've done x0 <- rnorm(100) x1 <- ifelse(x0 > 0 & x0 < 1.5,"t","f") x2 <- which(x1=="t",arr.ind=TRUE) x0[x2] Thanks. -- Muhammad ___

[R] cell-based high-throughput chemical compound screens package?

Re: [R] Jonckheere-Terpstra test using coin package?

I am unfamiliar with how to use coin, but it looks like it should be doable - the vignette in coin.pdf does a Page test. The wikipedia page for Page's test explains how this is related to the Jonckheere-Terpstra test, which seems to suggest if it can do one it should be able to do the other. Add t

Re: [R] densCols: what are the computed densities and how to create a legend

Hi Kate, the function does not directly return the calculated density values, however those can be recomputed through the internal function .smoothScatterCalcDensity This function is not exported from the grDevices name space, so you need to use the full qualifier: dat <- cbind(rnorm(100), rnorm
