similar to: help please: put output into dataframe

I've been doing some consulting with students who seem to come to R from SAS. They are usually pre-occupied with do loops and it is tough to persuade them to trust R lists rather than keeping 100s of named matrices floating around. Often it happens that there is a list with lots of matrices or data frames in it and we need to "stack those together". I thought it would be a simple

Dear All Sorry for this simple question, I could not solve it by spending days. My data looks like this: # data set.seed(1234) clvar <- c( rep(1, 10), rep(2, 10), rep(3, 10), rep(4, 10)) # I have 100 level for this factor var; yvar <- rnorm(40, 10,6); var1 <- rnorm(40, 10,4); var2 <- rnorm(40, 10,4); var3 <- rnorm(40, 5, 2); var4 <- rnorm(40, 10, 3); var5 <- rnorm(40, 15,

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

_mulx_u64 only exists when the target is x86_64. That's still not very portable. I'm not opposed to removing the bmi2 check, but gcc also has the same check so it doesn't improve portability much. ~Craig On Sat, Dec 29, 2018 at 4:44 PM Arthur O'Dwyer via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Hi Pawel, > > There is the _mulx_u64 intrinsic, but it

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

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, everybody: I asked about this in r-help last week and promised a summary of answers. Special thanks to the folks that helped me understand do.call and pointed me toward plyr. We face this problem all the time. A procedure generates a list of data frames. How to stack them together? The short answer is that the plyr package's rbind.fill method is probably the fastest method that is not

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

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

I am facing a problem with a function in survey package. The function svyvar gives the estimated population variance from a given sampling scheme. I am working with a data having more than four continuous variables. In order to have have population total for all those cont. variables I have written in the following format svyvar(~var1+var2+var3+var4+var5+var6,data) ; var1,var2,...,var6 are 6

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)
