similar to: Paste() - Get all possible combinations from multiple vectors

Hello all, I have the following problem: 1) A list was defined as 'a' a <- list("var1"=c(100:1), "var2"=c(1:100), "var3"=rnorm(100)) 2) a function 'foo' was defined that extracts the variable name assigned to x using the deparse(substitute()) functionality. This name will then be used within the function to generate specific output files, etc.

Is it possible to access the described class in a shared behavior? I''m trying to do something like this: describe "Siberian feline", :shared => true do described_class_instance_as :feline, :name => "fluffy", :breed => "Siberian" # or maybe before(:all) do @feline = described_class.new(:name => "fluffy", :breed =>

Hi Steven, Thank you for the help.

Hi R-help, I am trying to find a way to select five highest values in data frame according some variable. I will demonstrate: c X1 X2 1 1 1 2 1 2 3 1 3 4 1 4 5 1 5 6 1 6 7 1 7 8 1 8 9 1 9 10 1 10 11 2 11 12 2 12 13 2 13 14 2 14 15 2 15 16 2 16 17 2 17 18 2 18 19 2 19 20 2 20 21 2 21 22 2 22 23 2 23 24 2 24 25 2 25 So I

Hi all. I would like to highlight overlapping regions of two densities and I could not find a way to do it. Here is the sample code: myd <- c(2,4,5, 4,3,2,2,3,3,3,2,3,3,4,2,4,3,3,3,2,2.5, 2, 3,3, 2.3, 3, 3, 2, 3) myd1 <- myd-2 plot(range(density(myd)$x, density(myd1)$x), range(density(myd)$y, density(myd1)$y), type = "n") lines(density(myd), col=1, lwd=4)

Hi R users, I have following data frame df<-data.frame(q1=c(0,0,33.33,"check"),q2=c(0,33.33,"check",9.156), q3=c("check","check",25,100),q4=c(7.123,35,100,"check")) and i would like to replace every element that is less then 10 with . (dot) in order to obtain this: q1 q2 q3 q4 1 . . check . 2 . 33.33 check 35

Hi to all. I have a problem to connect to an Excel database using RODBC. Namely, I am using 64-bit R 2.14.0, under Windows 7 and I tried following: library(RODBC) > channel <- odbcConnectExcel("results.xlsx") Error in odbcConnectExcel("results.xlsx") : odbcConnectExcel is only usable with 32-bit Windows # ok this is clear why it doesn't work > channel

Dear BioConductor and R fellow users I apologize in advance for double posting, but I am not sure which list would actually be best fit for this message. I am experiencing a weird error with my R installation on Ubuntu 10.04.4 (LTS) 64bit: When I run R on the terminal everything goes smoothly: $R R version 2.15.2 (2012-10-26) -- "Trick or Treat" Copyright (C) 2012 The R Foundation

Hi everybody. I have list like this: l<-list(data.frame(q1=c(1,2,"check"),q2=c(3,"check",5)), data.frame(q1=c("check",1),q2=c(4,5))) names(l)<-c("A","B") rownames(l[[1]])<-c("aa","bb","cc") rownames(l[[2]])<-c("aa","bb") Every object has the same number of columns but different number

Hi, in order to save space for a publication, it would be nice to have a combined scatter and density plot similar to what is shows on http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=78 I wonder if anybody perhaps has already developed code for this and is willing to share. This is the reproducible code for the histogram version obtained from the site: def.par <-

I have a categorical variable in a dataframe similar to the following... cat 1 1 3 2 4 I need to convert it to 4 dichotemous variables for each observations like... cat1 cat2 cat3 cat4 1 0 0 0 1 0 0 0 0 0 1 0 0 1 0 0 0 0 0 1 Thanks in advance! Shane

Hello All, I am wondering if there has ever been any discussion/consideration given to incorporating MathJax (or something similar) into R for rendering equations in .Rd files. I know that equations are rendered beautifully in the pdf manuals, but I suspect the majority of users primarily look at the html help files when using R. While I am comfortable reading something like "B_x(a,b) =

Hello fellow Samba users and devs. This is my first post. I've searched documentation far and wide for Windows, Linux, and Samba, and have not been able to shed any light on this issue. I can't get more than 8MB/s during a single file copy stream out of my Samba server over my 100FDX switched network either from Win2K or WinXP (I don't have a *nix client to test with). The network

Thanks Gabor and Duncan! It works. For those interested, I added this to the beginning of the \details{} section: \if{html}{\out{ <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax at 3/es5/tex-mml-chtml.js"> </script> }} And then I can use: \if{html}{\out{\(B_{x(a,b)} = \int_0^x t^{a-1} (1-t)^{b-1} dt\)}} or

Yes. Thank you; I should have quoted it. I suggest to remove this text or to add the word "not" at the beginning.

Indeed: Using 'weights' is not meant to indicate that the same observation is repeated 'n' times. As I showed, this gives erroneous results. Hence I suggested that it is discouraged rather than encouraged in the Details section of lm in the Reference manual.

Hi R users. sorry for missing example and if question is to general but I am wondering if it is possible to execute subqueries in function sqlQuery (package RODBC) with opened connection with Excel or SQL server 2000. I couldn't find any example of this. And if it is possible what should be a correct syntax for this query: SELECT ct,COUNT(*) as n FROM (SELECT COUNT(*) AS ct FROM children

Hi R users.

Hi R users, could someone help me to find out which formulas, for standard error calculation, are used in following example: a=data.frame(weights=rep(c(10,1),c(4,1)),fpc=rep(41,5),uk=rep(1,5)) srs<-svydesign(id=~1, weights=~weights, data=a) srs1<-svydesign(id=~1, weights=~weights,fpc=~fpc, data=a) svytotal(~uk,srs) total SE uk 41 9 svytotal(~uk,srs1) total SE uk 41

Hi all. I tried to calculate sum of deviations from the weighted mean and i didn't get what i expected - 0. Here is an example: > wt <- c(10,25,38,22,5) > x <- 6:10 > wm <- weighted.mean(x,wt) > (x-wm)*wt [1] -18.70 -21.75 4.94 24.86 10.65 > sum((x-wm)*wt) [1] -1.24345e-14 With simple mean I got 0: > sum(x-mean(x)) [1] 0 Could someone explain me why we
