Dear R-helpers, I created an own function which looks like this s_elternmz <- function(Var="balt") { Dg_a<-mz[,c("asbhh","apkz",Var)] colnames(Dg_a)[colnames(Dg_a)=="apkz"]<-"bpkzm" colnames(Dg_a)[colnames(Dg_a)==Var]<-paste(Var,"_m",sep="")

Dear people, I have got a question concerning the underlying numerical codes when reading an SPSS file into R. I used the package foreign and when I look at a variable I get the verbal codes. I would like to know how it is possible to get the underlying numerical codes as output, which are the same as in my SPSS file. Thank you very much in advance for your help!

Dear list members, I have got another problem. I imported an SPSS file with the Memisc package using the following commands: mz <- spss.system.file("myspssfile.sav") mz <- subset(mz,select=c( bsex,balt,xurb,dtaet,kartab,bgeb,boseit,bgeblan,xnuts2,kausb,xerwstat, asbper,asbhh,ajahr,aquartal,bstaat,xwieoft,gew1,apkz,bpkzm,bpkzv)) Afterwards I checked the measurements of the

dear r-helpers, i created an object named A, which looks like this: A <- c("4.4","1.9","4.1") now i needed to get numbers instead of characters and for this i used the function: as.integer(A) which resulted in: [1] 4 1 4 My question is, why the numbers are rounded or more impotantly if there is a way to keep the decimal numbers? Thank you very much for

Hello all, I am looking for an editor for R which has got functions beyond the normal R editor that is included in the program.

Hello, does anyone know the solution to this problem: I imported a dataframe from Spss into R and saved it as an object called "kinderrechte". I have got the following command lines: q1 <- kinderrechte[,"q0007_0001"] l1 <- q0007_0001_l now i would like to be able to change the column name in the first command line (e.g. into q0007_0002) and to get R to automatically

Dear R-users, I am trying to make a plot with ggplot-geom_tile(), but cannot remove some unwanted (white) lines through my plot. Below a reproducible example: ##### library(ggplot2) tot=as.data.frame(rep(seq(-50,50,5),each=21)) names(tot)="precip" temp=rep(seq(-5,5,0.5),21) tot$temp=temp disc=array(dim=c(21,21)) for(i in 1:21){ for(y in 1:21){ temp<-

Suppose that I'm working on Hadley's diamond dataset and I want to review the relationship between price, colour and carat. I might run the following: library(ggplot2) #plot scatter and add some hex binning q<-qplot(carat,price,data=diamonds, geom=c("hex"), main="Variability of Diamond Prices by Carat and Colour") #facet to get one scatter for

Dear people, Yesterday I looked at the recode command in the memisc package and ran the following example stated in the manual: x <- as.item(sample(1:6,20,replace=TRUE), labels=c( a=1, b=2, c=3, d=4, e=5, f=6)) print(x) f <- as.factor(x) f recode(f,

hello, i am familiar with the paste command with which i can paste for exaple: object <- "Hello" paste(object,"World") now i would like to be able to paste all the elements of the same vector together e.g: object <- c("Hello","World") getting as a result also: "Hello World". Does anyone know the solution to this problem? Thank you

Hi Listers, Is it possible to produce an ordination plot in 2d, where bubbles represent the location of sites (this part is easy enough) and the size of the bubbles is proportional to the sites location in 3d space (I am stuck on this option). So sites that are very near the 2d plane of the xy axes would be larger while sites that are actually further away in 3 d space would be proportionally

Hello everyone, I was asked to repost this again, sorry for any inconvenience. I'm looking replacement for ddply function from plyr package. Function allows to apply function by category stored in any column/columns. Regular loops or lapplys slow down greatly because my unique combination count exceeds 9000. Is there any available solution which allow me to apply function by category?

Hello, I have a question concerning courses in R in *Vienna, Austria*. Does anyone know where courses in R are offered, that you can do after having attended a course for the basics? Thanks in advance for your help. Marion [[alternative HTML version deleted]]

Dear people, I created a plot which looks like this: Ee1<-matrix(c(88,86,74,62,41),ncol=5) colnames(Ee1)<-c("Lehrer","Lehrerinnen","Klassenkollegen","Klassenkolleginnen","Geschwister") par(las=1) par(mar=c(5,13,4,2)) barplot(Ee1,horiz=T,col="grey85",border="NA",xlim=c(0,100),axes=F) axis(2,pos=10, tick=T, tcl=F,

Dear r-helpers, I read a .csv file into R with the following command: A<-read.csv2(file="Mappe3.csv") It worked fine, except that I would like to get rid of the points between the words and get spaces instead like I have got in the .csv file. At the moment it looks like the following: habe.mich.gut.mit.KlassenkollegInnen.verstanden hatte.gutes.Verhältnis.zu.Eltern
