I've writen this function (imagenrgb) to display a (m,n,3) array as a RGB image with ngris^3 colors and,optionally, stretching. If option ver=F, it does not display but saves a pseudocolor version of the image as a list (so that subsequent displays are faster). I'd appreciate feedback and improvements and hope that it's useful for others. Example of use: > dim(imatest) [1] 100

Hi all, I am trying to convert a data set of physician death codings (each individual's cause of death is coded by multiple physicians) from long to wide format, but the "reshape" function doesn't seem to work because it requires a "time" variable to identify the sequence among the repeated observations within individuals. My data set has no order, and different

I'm trying to get a minimally intuitive way of plotting zoo objects extracted for given periods of time I do: > plot(alyL32007z$NEE_st,col=cod,type="b",pch=18,xlim=time(alyL32007z)[c(3000,15000)]) and get a correct plot but the expression for xlim is hard to read by humans. I try > time(alyL32007z)[c(3000,15000)] [1] "2007-03-04 11:30:00 UTC" "2007-11-09

Hello, I have two different dataset, and wanted to join the two. For example I have a table of codes of cities, and other with with the codes of travels, [source for the destine]. what he wanted was to have a new data.frame with all the information city<-data.frame(city="Barcelona",cod=1) city<-rbind(city,data.frame(city="Madrid",cod=2))

Good Morning, I'm having what I hope to be a simple problem. I am generating bootstrap confidence intervals using package (boot) - which works perfectly. The issue I am having is getting the results into a format which I can write out to a database. To be clear I am having no problems generating the results, I just need to convert the format of the results such that I can store the results in

Hi, I'm looking to combine two data frames. Several of the columns are in common while the others need to be summed up. The apply functions and the merge functions don't seem to be working. I've included a basic example of what I'm trying to do below. Thanks! Sean data.frame1<-as.data.frame(matrix(c('winter','dredge','515',100,150),1,5))

Hello, I have tried to find this out some other way, but unsuccessful I have to try this list. I assume this should be quite simple. I have a dataset with 4 columns, "Sample_no", "Species", "Nitrogen", "Carbon" in csv format. In the species column I have many different species with varying number of obs per species Eg "Sample_no"

I have some specs that involve the use of eval and class definitions to test code generation. I want to always start with a clean slate so none of my tests fail or succeed incorrectly due to artifacts left over from previous specs. Example of my situation Spec 1 defines class Fish class Cod < Fish Spec 2 defines class Animal class Cod < Animal In this situation the

I'm attaching an small text file on "Getting your stuff organized in R". (Sorry if sending an attachment is not considered a correct etiquette in r-help, but this is only 7911 bytes, plain ascii text and I cannot post it in a web page at the moment). Probably all the information in this document is scattered in one or more R introduction guides, but I think that it is useful to have

Hi -I'm running a GAM with 7 explanatory variables with a Poisson error structure. All of the variables are continuous so I'm getting error messages in R. cod.fall.full.gam.model<-gam(Kept.CPUE~s(HOUR)+s(LAT_dec)+s(LONG_dec)+s(meantemp_C)+s(meandepth_fa)+s(change_depth)+s(seds), data=cod.fall.version2,family=poisson) In dpois(y, mu, log = TRUE) ... : non-integer x = 5.325517

Here I am again with question I'll feel foolish for asking, when I see the answer. I'm trying to produce a report and here's where I get stuck: How do I get R2HTML to produce the same number format? Particularly remove the decimal places for Par and Sal. Are there better methods to produce this type of report? Thanks, L.A. R version 2.10.0 XP

I ran a function called BoxCox, taken from the book by Venables and Ripley, for checking the need for power transformation. This function works fine using the version 0.50 of R, but gives an error message with version 0.60. The lm function in version 0.60 is different from that in version 0.50. Is there a bug in the new lm function? Kung-Sik Chan >

Hello, we've had some serious trouble with a two-node Xen-based OCFS2 cluster. In brief: we had two incidents where one node detects an idle timeout and shuts the other node down which causes the other node and the Dom0 to hang. Both times this could only be resolved by rebooting the whole machine using the built-in IPMI card. All machines (including the other DomUs) run Centos 5.2

CoD: Black Ops - Runs Slow On Good Computer? Hi, Here is my system: - Ubuntu 10.10 32bit Linux - 3.0GHz Intel Core2Quad Extreme 4-core - 8GB DDR2 RAM - nVidia GeForce GT 240 1GB DDR5 - Current Wine 1.3.7 Game uses only Direct X 9 so am puzzled as to the poor performance? Any tips to make it run faster? (other than a faster computer) Thanks! Jesse

Hi LLVM Developers, I have a query about an LLVM error message that I'm encountering and I hope it's appropriate to post to this mailing list about it. Postgres can be built with LLVM-based JIT support. I find that when running on Linux (RHEL8) on IBM Z hardware, using LLVM8+, I'm seeing many instances of the following LLVM error message appearing in the Postgres server log: ORC
