Hello Rxperts.. I have a peculiar situation.. XML library is not available with R2.15.1 whereas I was able to install it with R version 2.13.1. Would highly appreciate your suggestions.

Dear R gurus.. Is it possible to control span settings for different values of a grouping variable, when using xyplot? an example code shown below d=data.frame(x=rep(sample(1:5,rep=F),10),y=rnorm(50),z=rep(sample(LETTERS[1:2],rep=F),25)) xyplot(y~x,data=d,groups=z,panel=panel.superpose,panel.groups=panel.loess(span=c(2/3, 3/4,1/2)) or something like..

Dear Rxperts, I am aware of Sweave that generates reports into a pdf, but do know of any tools to generate to export to a MS Word document...

Dear Rxperts, Through Windows OS, I created shortcuts (paste as shortcut) to excel spreadsheets ( with "xlsx" as the file extension). I wasn't able to read the shortcuts through R and using "read" functions of "xlsx" package. exf <- "a1.xlsx.lnk" > read.xlsx(exf,1) Error in .jcall("RJavaTools", "Ljava/lang/Object;",

Dear R-gurus aa <- data.frame(a1=rnorm(20),b1=rnorm(20,0.8),c1=rnorm(20,0.5)) sapply(aa,function(x) histogram(x,breaks=NULL)) or px <- sapply(aa,function(x) histogram(x,breaks=NULL)) print(px,split=c(1,1,1,1),more=F) The above code does not seem to work. am I missing something?

Dear R'sians, Would really appreciate if you could suggest a more efficient way to order the columns of a dataset. The column names of the dataset contain indices separated by a period. Following are examples of my code and the dataset. oC <- function(tg=x2) { lth <- length(grep("T",names(tg))) thix <-

Dear Rxperts! I was wondering if it is possible to write a function which can take in argument of a subset or condition.. Of course, I am aware of the alternate methods like coplot, par.plot, xyplot etc... I am specifically interested in using conditions/subsets with "plot".. A simple fragmented example is shown here.. pltit <- function(y,x,dat,dat1,dat2,sbst) { plot(y~x, data=dat,

Dear Rxperts, How do I hide the top and right axes in multiple panel plots? A couple of examples are provided below.. Would highly appreciate appreciate your assistance.. #Example 1 library(latticeExtra) xyplot((1:200)/20 ~ (1:200)/20, type = c("p", "g"), scales = list(x = list(log = 2,alternating=0), y = list(log = 10,alternating=0)), xscale.components =

Hi R-users, Was wondering if there is a way to quickly compute correlations between continuous variables grouped by some categorical variables? What function do I use? Thanks much in advance. Regards, Santosh [[alternative HTML version deleted]]

Dear Rxperts.. what settings in barplot and histogram do I use, to show bars in an monotonously increasing or decreasing order of the frequency of a categorical variable? an example is provided below.. histogram(~factor(sample(letters,200,rep=T))) I was able to get it in 3 - 4 steps.. l a1 <- sample(letter,200,rep=T) a2 <- table(a1) barplot(a2); barplot(sort(a2)) # all variables are not

Dear R experts.. I am trying to understand what exactly strptime and strftime do... Where can I look for the detailed notes on these two functions? In addition, how POSIX functions like POSIXct and POSIXlt are used in these functions? Regards, Santosh [[alternative HTML version deleted]]

Dear R'sians.. I apologize if this topic has been beaten to death and hope that hawks don't pounce on me! Could you please suggest an efficient way to filter rows from 500+ text files (some with 30000+ rows with multiple section table headers) residing in several folders? I guess probably "scan" is the fastest way to scan a file, but, I noticed it sometimes takes a long time

Dear Rxperts! My colleagues used SAS PROC COPY to generate the xpt files that could be read by the available "xpt" file reading packages in R. However, I am unable to use the R packages for reading SAS transport files generated through SAS PROC CPORT. I have tried SASxport, Hmisc, and foreign. Any ideas/suggestions are more than welcome! Thanks so much! Santosh [[alternative HTML
