Dear R community members I have been struggling on this simple question, but never get appropriate solution. So please help. # my data, though I have a large number of variables var1 <- rnorm(500, 10,4) var2 <- rnorm(500, 20, 8) var3 <- rnorm(500, 30, 18) var4 <- rnorm(500, 40, 20) datafr1 <- data.frame(var1, var2, var3, var4) # my unsuccessful codes nvar <- ncol(datafr1)

Hello just learned HowTo but R, reminded me with the way Perl does it but with much less on-line commands, R "AFAIK" has n, c, Q and where and cann't debug outside the {}. 1) is there a more versatile/flexable debugging method for R? I have saved 2 functions in an ASCII file "digfun". "getdata" function calls "squash" function and both use loops. In

Hi all, I have a function getSomeData() that is called from command line - getSomeData(id='1240'). The function getSomeData() calls another function getData that needs the exact same argument passed to getSomeData(). I am using the function call getData(paste(names(args[1]), "=", sQuote(args[[1]]))). The argument passed is- id='1240'. The problem is that in

Hi all, When I check my package using "Rcmd check ..\myPackage\R.mykg" on Windows in Command Prompt, this is what get:- * using log directory 'C:/R/bin/R.getdata.Rcheck' * using Version 2.3.1 (2006-06-01) * checking for file 'R.getdata/DESCRIPTION' ... OK * checking extension type ... Package * this is package 'R.getdata' version '1.0' * checking

hi list, i am making some diagnostic plots using plot.lme(), my lme model was fit with the option na.action='na.exclude'. On the following (or similar) commands: plot(flu.trees.42.w25.10.2, resid(., type="p") ~ fitted(.)|species, abline=0) R returns an error message: Error in getData.lme(object) : couldn't find function "naAct" It turns out that the function

I noticed some very weird behaviour of the function: options(digits=n), where n is the number of digits you would expect to get in R calculations. Let's take a example: > options(digits=4) > getdata(caso.pool.k3.r3.e2) [1] 6.053 2.641 -3.639 14.259 6.082 Which works fine... now, trying again, with different data: > options(digits=4) > getdata(controle.pool.k3.r3.e2)

Hi, "Writing R Extensions Guide" clearly states that a C-function interfaced via .Call() should not modify any of its arguments. However I wonder if there are exceptions to this rule, i.e. when .Call can safely modify the arguments. For example when a function creates a list that is then populated by a call to a C function: getData <- function() { data <- list(a=double(2),

Dear Helpers   I have a sample frame and i have sampled from it using three methods and now i want to calculate the statistics but i only get the population parameters.   H <- matrix(rnorm(100, mean=50000, sd=5000)) sampleframe=data.frame(type=c(rep("H",100)),value=c(H)) sampleframe   str=strata(sampleframe,c("type"),size=c(20,), method="srswor")

HI. I make this code: getdata<-function('a','b','c' ,'d','e','f'){ drv <- dbDriver("SQLite") con<-dbConnect(drv, "sqlite.db") lt<-dbListTables(con) myf<-data.frame(NULL) for (i in 1:length(lt)) { myfile<-dbReadTable(con,lt[i]) myfile1<-myfile[-c(14:44)] myfile1$MODEL<-gsub(" ",

Might not be the best place to ask, but i could get lucky.. I have setup an eclipse environment to write sweave files lately and wanted to switch to knitr. I could get it to work on easy files, but my earlier written sweave file fails to be knit properly. Here is the error message: Quitting from lines 273-276: Error in setwd(base.dir) : kann Arbeitsverzeichnis nicht wechseln (it says: cannot

Hello! I have 2 maps - both created in ssplot and both identical in terms of outline. Is there any way to superimpose Map1 (which has black borders between Canadian provinces) onto Map2 (which is also a map of Canada)? Thanks a lot for your hints! Dimitri ### A. Reading in Canada data at the province and then at the county level: library(raster) getData('ISO3') # Canada's code is

Hi, i am trying to connect to a DB2 server using the DBI library. getData <- function() { driver <- dbDriver("DB2") conn <- dbConnect(driver,"server","uname","pword") data <- dbSendquery(conn, "select etc.") } When I run the function, i get the error > data <- getData() Error in

Hello, I am wondering about the X11() graphic device on Windows. I try to plot a raster image but nothing gets displayed. I found some pages where it is mentioned that x11() not always supports raster rendering. Is there any add on for x11, any update or any R-package which solves that displaying problem in Windows? What I try to test it is an example from the package {raster}: library(raster)

Before coming in here , I had a deep dig into Google and couldn't find an answer, Simply spoken, using agi->getdat in an AGI application , the call disconnects if digits are entered fast by user. I'm certain that others have been though this problem, please pour your experience here :-) . Ali Mughrabi

Seeing the below commit, I wondered whether that's a genuine fix or rather a workaround for a shortcoming in llvm::ScopedPrinter::printNumber. The latter has overloads for [u]int{8,16,32,64}_t, presumably so that it can take arguments of arbitrary integer types. However, at least on recent macOS uint64_t is 'unsigned long long' (and uint32_t is 'unsigned int') while

Hi, I have been studying the R manual on lists but cannot seem to create a simple R list in C - I keep on getting "'dimnames' applied to non-array" whenever I attempt to assign names to the list elements: Wanted output a list structure something like [ type="Bid", price=2.0, volume=1000 ] I can get up to a list of [ "Bid2, 2.0, 1000 ] But for the life of

Dear R gurus, I have a very embarrassingly parallelizable job that I am trying to speed up with snow on our local cluster. Basically, I am doing ~50,000 t.test for a series of micro-array experiments, one gene at a time. Thus, I can easily spread the load across multiple processors and nodes. So, I have a master list object that tells me what rows to pick up for each genes to do the t.test from

Currently virt-v2v attempts to create an iso containing all software referenced in the config file before starting. If any software isn't available it displays an error and exits immediately. With this change it will ignore software which isn't available at iso creation time. Instead, it will only display an error if the unavailable software is actually required. This is much kinder to
