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

Please, do not ask why you would do this. I have simplified my complicated code to just the basic problem occuring to be able to make it easier to understand the actual problem. I have two function getArgs() and extractArgs() - code and test results provided below. I test them using getArgs(id = 's1002') from the command line. getArgs() prints the name of the argument as id and the

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

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),

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 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(" ",

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

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

So, I was looking for a setup that would allow me to easily query multiple databases and not have to re-write my customer finder type queries. Here is what I came up with and it seems to be working for me in my very basic tests so I thought I''d share. Just posting it in case this helps anyone else trying to do the same thing. I''m using this with activerecord, but not rails, so

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

Hello getdata <- function(p){ fname <- NULL; dl <- list()#build the sturcture builddl <- function(q,s){ fname <<- c(fname,s) #where "s" is a string dl <<- list( dl, dt2) } list(names = fname, data = dl) } data <- getdata("c:\somepath") > data $names [1] "fname" $data $data[[1]] <--- since there is no [[1]] how can I stop

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")

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)

Dear R users- Do the lattice/latticeExtra packages support multiple tileplots with unique colorkeys? I am trying to create a visualization of the encounter rate of certain stocks of salmon across two years. The issue I am having is that some stocks are encountered at much higher rates than others.the high encounter rate for one stock washes out the patterns I'm hoping to visualize across the

Hi, I am trying to migrate print queues from a windows server to a samba share. 1. I ran printmig.exe on the windows server. 2. Backed up the printers on the windows servers to a cab file. 3. Tries to restore the printers to the sambashare by specifying the target as //sambaShare. But I get the following error: 2006:01:25 15:35:38 Access Granted to: \\sambaShare 2006:01:25 15:35:38
