Dear guRus, I'd like to learn how to make a function recognize the name of an object/vector given as argument If I have : testFun <- function(x,y) plot(x,y, main=paste("plot of",names(x),"and",names(y)) ) # this just a simple example ... a1 <- 5:8 b1 <- 9:6 testFun(a1,b1) # Returns the plot, but not the names of the objects/vectors given as arguments, # but

I have some questions about the RODBC package. library(RODBC) # required for those who want to repeat these lines 1st, I noticed that the following sequence does not work: channel <- odbcConnextExcel("test.xls") tables <- sqlTables(channel) name1 <- tables[1, "TABLE_NAME"] # this should be the name plan1 <- sqlFetch(channel, name1) # bang!

Dear list, I have encountered a special case for searching a linear regression where I'm not satisfied with the results obtained using the traditional least squares method (sometimes called OLS) for estimating/optimizing the residues to the regression line (see code below). Basically, a group of my x-y data are a bit off the diagonal line (in my case the diagonal represents the ideal or

Hi: I am working on a publication and I have heard about LaTEX but I haven't actually tried to learn about it until today. I've found a few examples but I can't actually make them work properly. I have a couple of questions: Does LATEX have to be installed on your computer? How does the xtable package and Sweave work together? How can I make the code below create a table as pdf file?

Dear List, when reading MS Excel files in R using package RODBC I encountered the problem of having the first line of data getting omitted. I read the data as : > library(RODBC) > channel1 <- odbcConnectExcel("myFile.xls") > sheet1 <- sqlQuery(channel1, "SELECT * FROM [Cell measures (1)$]") # I use sqlQuery() instead of sqlFetch() since the sheet I

Dear list, when running a mood.test() (part of package "stats") on slightly longer vectors (than the example from the help-page) we get the error-message shown below : once both vectors tested are of length 50 this error oocurs. Note, that this problem didn't occur with R-2.7.x (or even older versions). > x <- rnorm(50,10,5) > y <- rnorm(50,2,5) > >

Dear guRus, I'm maintaining central R installation (Linux) for our institute. The startup screen of R traditionally echoes some messages (starting with "R version ...Copyright (C).. The R Foundation for Statistical Computing...") and I'd like to display for example right after these messages some other messages about our specific setup, how to contact me etc ... What

Dear list, I'm wondering how to optimize functions/processes like the one shown below (which simplifies something we're trying to do with very large datasets). In many cases I've noticed that using apply, sapply etc can help speeding up processes, but in this case I don't see how I could do so. a <- runif(10000000,0.5,1.6) C <- 2 M <- 10000000 system.time( for (i in

Dear list, ?require says : "... |require| is designed for use inside other functions; it returns |FALSE| and gives a warning (rather than an error as |library()| does by default) if the package does not exist ..." However when I run the following code I don't get any TRUE / FALSE statements (but the warning only). Since I want to test from inside of a function if a given package

Dear list, so far I installed new versions of R on top of the old one in default /linux/local/lib64 . For several reasons (mostly compatibility issues) I would like to change this and to keep older versions still functional/available. Furthermore this should allow to perform installing and testing completely independent of any user still using a precedent version of R, and the switch for users

Dear list, I?m using R embedded in another program (coded in tcl/tk) under Windows Vista. In this context I don?t launch Rgui.exe but rather Rtem.exe. Now I have a problem finding libraries not specifically installed as administrator (and which are not in the path ?program files? but in Contacts\Documents of the current user). To be precise, the user launching my tcl/tk program can?t find
