Hello,

thank you very much for your answers. Using the command ncol worked in my
special case, if I have got a legend with 4 elements, but with 5 it doesn't
work. I am using two functions which I had created and checked what might
be the difference, so that the second one doesn't work, but I couldn't find
out what the problem is. So I am including the text of my .csv files and my
functions:


My .csv file "abb8a" looks like this:

;sehr gut;eher gut;eher nicht gut;nicht gut
Kontakt mit der Schule;46;49;4;1
Die richtige Wahl;32;58;8;2


mw_g_4stap<-function(pfad="F:/04 Archiv/04 Programme/19
R_Syntaxe/Grafiken_Funktionen",abb="abb8a")
{
  setwd(pfad)
  postscript(file=paste(abb,".eps",sep=""))
  dat<-read.csv2(paste(abb,".csv",sep=""),header=T,check.names=F)
  dat1<-t(as.matrix(dat[,2:5],nrow=2))
  colnames(dat1)<-dat[,1]
  zehn<-seq(10,100,10)
  xmax<-max(dat1)
  ind<-min(which(zehn>=xmax))
  ticks<-seq(0,100,10)
  par(las=1)
  par(mar=c(5.9,4.5+0.3529412*(max(nchar(colnames(dat1)))-1),1,1))

barplot(dat1,width=0.61,horiz=T,col=c("steelblue4","steelblue2","lightsteelblue3","lightsteelblue1"),border="NA",axes=F,beside=F,xlim=c(0,100),cex.names=1.2,ylim=c(0,10))
  par(xpd=TRUE)
  abline(v = seq(10, 100, by = 10), col = "white")
  par(xpd=F)
  axis(1,at=ticks,las=1,labels=paste(ticks,"%",sep=""))
  par(xpd=TRUE)

legend(0,-1.4,xjust=0,ncol=2,legend=colnames(dat)[-1],fill=c("steelblue4","steelblue2","lightsteelblue3","lightsteelblue1"),bty="n",border="white",cex=1.2)
  par(xpd=FALSE)
  dev.off()
}
mw_g_4stap()

My .csv file "probe8_5" looks like this:

  par(xpd=TRUE)

  dev.off()
}

The first function works but the second one doesn't.

Does anyone know why?

Thank you very much for your help in advance!!
