This is what to start with: Data Frame A B C D c1 4 y 5 c3 6 d 7 c1 5 t 6 Now sort on A then C This is what to end with: Data Frame A B C D c1 5 t 6 c1 4 y 5 c3 6 d 7 I assume it is something like this: attach(DF) sort(DF,partial=c(A,C)) Thanks in advance.

Hi, Thanks for reading. I am running a process in R for microarray data analysis. RedHat Enterprise Linux 4, dual AMD CPU, 6G memory. However, the R process use only a total of <200M memory. And the CPU usage is total to ~110% for two. The program takes at least 2 weeks to run at the current speed. Is there some way we can increase the usage of CPUs and memories and speed up? Any

Hi, I’m trying to built a simple function that allows me to export automatically some results to a text file. I’ve tried the two following approaches but none worked. > exportdata<-function(x) { + dataexp<-summary(x) + export(dataexp,type="ascii",file="dataexp.txt") + } > exportdata(glm.poisson0) Error in eval(expr, envir, enclos) : object

Hi I am trying to print out means, STDs and histograms under two sets of factors. I can manage it for one set - see below but not for two sets. That is, I want ot print out the mean STD and Histogram for each ITEM code within each DELIVERABLE code. In addition I can only get to view the histogram for the last item. How do you get R to stop overriding the histogram for eg level 1 for factor 1

Thanks Mike. My data has longitude and latitude coords and I used distAB {clim.pact} then mst {ape} to calculate my minimum spanning tree. The nodes are telecoms sites from all over Australia. My goal is to determine the minimum cost of linking them via cabling, and I'm starting by calculating the distance "as the crow flies", but will probably eventually need to calculate the

Hello I have to show that R has more functionality than SAS for MonteCarlo type exercises involving matrix algebra. As I has little experience with SAS is anyone able to help. I have a model written in R but the IT world in this company is not familiar with R and wants to use something like SAS. thanks

r-help, Is there a package available for R which allows you to export data directly to .xls, much like exportData(foo,"foo.xls","EXCEL") in S-PLUS ? If not, is anyone working on this, or thinking about working on this? I apologise in advance if this question has already been answered. Many thanks, Matthew

Hello Instead of reading in group1.txt I want to read in groups1 for the first iteration of i, then groups2 for the second and so on. Obviously I can't use groups(i) but assume there is a way to do this. group<-read.table("C:/Data/April 2005/group1.txt",header=T) thanks in advance Meredith

Dear all, i use the following package/syntax to export data to excel: library(xlsReadWrite) write.xls( exportdata,pfad,colNames = TRUE,sheet = 1,from = 1,rowNames = FALSE ) Everything is fine, but the format of the export is not the best. For example, I every time have to adjust the column width. Furthermore there is no possibility to highlight some cell or make them colourful. I create a lot

Hello I'm not sure I'm using boot correctly: I have a list of values for a variable in BUCKET[, j] I want to use function 'boot' to estimate a confidence interval on the mean of the non-zero data. The data can be bi-polar or skewed. Is this the correct use of boot to establish a mean and standard deviation or median and percentiles? x<-BUCKET[, j]

Hello I'm wanting to understand more about ptrend (a statistical explanation via an internet website if possible) and also to know what package in R would produce a ptrend. Appreciate any help I can get on this as I'm trying to read and understand an epidemiological paper and data and reproduce similar results for my own understanding. Thanks Meredith [[alternative

Hello there, I spent all day yesterday trying to get a small data set from Splus into R, no luck!

Hi Is there an R package that solves linear least squares with upper and lower bounds on the variables. Something like the Parker and Stark algorithm written in Fortran. thanks

Do you know if you can map in R? I have my minimum spanning tree, but as there are 1371 nodes (all over Australia) I'd like to be able to "graph" them as they actually would be on the map. Do you know if this is possible?

Hi all I am converting an S-Plus function into R. The S-Plus code uses some of the glm families, and family objects. The family objects in S-Plus and R have many different features, for example: In R: > names(Gamma()) [1] "family" "link" "linkfun" "linkinv" "variance" [6] "dev.resids" "aic"

I live in New Brunswick Canada. The phone company is Aliant. When you set up business service here, you can go with either analog or digital lines. This isn't a T1 or ISDN. They are talking individual lines direct to handsets that they provide. They offer the digital option with even very small ( 2 - 4) number of lines. What technology could this be? Is there any way to connect such a
