Hello, I am wondering if it is possible to compute a rowsums using a list, and also, filter the sum by a condition from a third variable. I thoght in something as ghj : data frame list_g=("va1","va2",var3") ghj$jkj[ ghj$var4=10 ]=apply(ghj[,list_g],1,rowsums) The syntax before clearly...

Hello, I am in the need of estimate the CVs and SE from a proportion. I mean, I have a variable with categories. I need to obtain the errors from the proportions of each category over the total sum. I can total estimates flawlessly the CVs or SE with svytotal, but I'm missing something with the...

Hi, I need to plot bars and line using the data frame named mydata2. I am able to plot only bars using : library(ggplot2) p <-ggplot(mydata, aes(as.character(months), y=values)) p +geom_bar(stat = "identity", aes(fill = type), width = 0.6, position="dodge")+ xlab("trimestres")+...

Hello, I want to perform the following aggregate: aggregate(fact~cis+sex,data=subset(bbdd,cis>0 ),FUN=sum) but using the vector zone to have multiples tables. I already did it with a loop, but that's not the purpose of R, i think: for (i in 1:max(zone) { nn=paste("base",i,sep="_")...

Hi, I have a R script. My plan is to use rmarkdown and import some values and tables from the global environment produced by the R script. I've been trying to do that, but I always get errors. I mean, for example, how can I import the values from the vector "zxc" into knitr in order to print it...

Hello, I need to calibrate a survey using raking. I already declared the complex design here: des_survey <- svydesign(id= ~idd, strata= ~strata, data = datos, weights = ~ft, check.strata=TRUE ) options(survey.lonely.psu = "remove") options(digits = 10) However, when I run the rake process...

Hello, I'm trying to avoid a loop to do this zz=matrix(NA, nrow=40,ncol=1) for (i in 1:40) { wer=table(id[qwe==i],strata[qwe==i]) df=nrow(wer)-ncol(wer) zz[i]=df } The variable qwe goes from 1 to 40, and I need the nrow-ncol from a crossing two variables (id, strata) Is It possible to...

Hi, My problem seems simple, but I'm a bit lost. I have two variables, X1 and Y1. X1 and Y1 are the way a product is classified by the team X1 and Y1. X1: team X1 coding Y1: team Y1 coding And I need to test if the change (relative) between t and t+12 is different or not when I compare X1 and...

Hello, I need to compute some ratios using a survey. I manage to calculate regional totals after especifying a list of variables (regions). Regions are dummies from 1 to 17, taking the value of 1 if the observation belongs to the region1. This code works. It computes totals by regions using the...

Hello, I'm writing a code and I need to name the matrix row names with the local created from levelsof applied to var1 (variable 1). I already created the matrix using as reference a local (levels) using levelsof length. I tried something simple as this matrix rownames=`levels' Stata returned...

Hello, I have a data frame. I generated some dummies using a simple loop. However, I can't concatenate the dummies to the original data frame. yyy=max(region) for (i in 1:yyy) { nam=paste("region",i,sep="") assign(nam,as.numeric(cise>0 & region==i))...

Hello, I have no idea how to report in a vector the commons variables from a data.frame or matrix. I have a data many columns. In this example I show four columns with d1-d4 as names. So, how do I create a vector with the common strings? Something as this: It looks simple, but...

Hi, I need to read multiple dta files and exporting the content of a variable called "name". My idea is to aggregate to the right each "name" from each dta file. I made a simple loop and I know It works reading the dta files. However, It can't say the same exporting the data. Here is what I...

Hi, It's been a while since I asked this, so I will try again: Is there any form to import a SPSS file on R but in the way SPSS deals with them? I mean, working with labels? R and the packages that provides the import tool just import one way the spss file. The numbers or labels, but not both...

Hi I need to run the same syntax over some files. They are in the folder named DBase. I mean, there is a db01.sav and over it run the syntax, then do the same for db02.sav and so on. How do i make it? How run the process only listing one time the files i'm interested? Thanks for your time...
