Hi, I have the file below called happyguys. It is a subset of data. How do I apply the weight variable (WTPP) to this file? Can i just multiply each column (except the first column because it is a record id) by WTPP? If the answer is yes, how do I multiply one variable name by another? Thanks, Nat PROV REGION GRADE Y_Q10A WTPP 83 48 4 7 2 342233324020 115

Hi, I got this working. i had to get rid of an underscore in one of my variable names to work on RWeb. Thanks for your help though!! Natalie __________________ I think you have to be either honest or careful, since the code you submitted to Rweb is different with your former code! Why the condition was changed from "test<-subset(X, GRADE == 7 & Y_Q10A < 9)" to

Hi, How are you? I have a quick question.... I have code that works perfectly with R desktop, but does not work with RWeb. Could you please tell me how to modify the code below so it will work with RWeb? #Read in txt file happyguys<-read.table("c:/test8.txt", header=TRUE, row.names=1) #Subset the txt file to only include certain values test<-subset(happyguys, GRADE == 7

Hi, I've written code to extact a pumf file in R, subset it, and weight it like you would do in SPSS. My code is below & it works great. My question is: how do i then calculate the frequencies of smokers (1) versus non-smokers (2) after having weighted my file? or even the process that SPSS is going through to aggregate the data? Thanks, Nat Here is my code:

Thank-you Andy!!!!!! That works great now Nat __________________ I've run into this occasionally. My current solution is simply to read it into Excel, re-format the offending column(s) by unchecking the "thousand separator" box, and write it back out. Not exactly ideal to say the least. If anyone can provide a better solution in R, I'm all ears... Andy From: Natalie

Dear R-helpers, I'm not a speciallist in writing complex functions, and the function still very rusty (any kind of suggestions are very welcome). I want to implement Gale-Shapley algorithm for R Language. It is based on http://www.jstor.org/stable/10.2307/2312726 Gale and Shapley (1962) , and it has evolved to

Hi, Can anyone tell me why I am not getting the correct intervals for fixed effect terms for the following generalized linear mixed model from HPDinterval: > sessionInfo() R version 2.4.1 (2006-12-18) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

Hello: Forgive me, this is surely a simple question but I can't figure it out, having consulted the help archives and "Data Manipulation With R" (Spector). I have a list of 11 data frames with one common variable in each (prov). I'd like to use lapply to go through and recode one particular level of that common variable. I can get the recode to work, but it only returns the

I believe that I have incorporated all of the feedback given (thanks!). Changes since the 2008-11-16 version include: - ksh style & coding standards compliance in test script (Roland) - "dof_init_debug == B_FALSE" vs. "!dof_init_debug" (Adam) The updated webrev is at: http://cr.opensolaris.org/~mgerdts/6750659-2008-12-03/ -- Mike Gerdts http://mgerdts.blogspot.com/

I've posted the following to R-help on May 15. It has reproducible R code for real data -- and a real (academic, i.e unpaid) consultion background. I'd be glad for some insight here, mainly not for myself. In the mean time, we've learned that it is to be expected for anova(*, "marginal") to be contrast dependent, but still are glad for advice if you have experience. Thank

Hi All, I *think* it's ddply because the function recognizes vr1, etc, in other parts of the function. Here's some code: # create dataset PROV.PM.FBCTS <- c(0.00 ,0.00, 33205.19, 25994.56, 23351.37, 26959.56 ,27632.58, 26076.24, 0.00, 0.00 , 6741.42, 18665.09 ,18129.59 ,21468.39 ,21294.60 ,22764.82, 26076.73) FBCTS.INV.TOT <- c(0 , 0, 958612, 487990, 413344, 573347,

Hi all, If the question below as been answered before I apologize for the posting. I would like to get the frequencies of occurrence of all values in a given variable in a multivariate dataset. In short for each variable (or field) a summary of values contained with in a value:frequency pair, there can be many such pairs for a given variable. I would like to do the same for several such variables.

Hi, I am getting a warning message when I am fitting a generalized linear mixed model (m1.2 below). CHOLMOD warning: matrix not positive definite Error in objective(.par, ...) : Cholmod error `matrix not positive definite' at file:../Supernodal/t_cholmod_super_numeric.c, line 614 Any idea?

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. More specifically, I have fitted a cross-section model on data regarding Italian "counties" (province, for Italian readers) and I would like to visualize residual behavior on a map, in order to have a first assessment of their spatial

Hi there I'm trying to fit a logistic regression model to data that looks very similar to the data in the sample below. I don't understand why I'm getting this error; none of the data are proportional and the weights are numeric values. Should I be concerned about the warning about non-integer successes in my binomial glm? If I should be, how do I go about addressing it? I'm

I've been noticing that my group of Polycom IP 501 phones seems to randomly reset themselves nearly every night (I guess it usually happens at night, since I've never seen it happen while I've been at work during the day).. When I say "reset", I mean, the hands free volume and ring volume are set to the default and the call logs (received calls, missed calls, placed calls)

Estimados compañeros tengo el siguiente problema: quiero poner etiqueta a los valores de una variable. He creado una lista que se llama geren que tiene 194 valores distintos.

Hi everyone, I am putting together an application in which each part of it was tested individually. Now that it is put together, I''m having problems... The one giving me problems is my "ImportController" which parses a CSV during post and puts it into my database. I have two separate CSV upload actions (one is for a bill called "bes" and the other from the provider
