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

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()
}

The first function works but the second one doesn't.
Does anyone know why?
Thank you very much for your help in advance!!

dear r-helpers,
i have got another question:
i am using the functions
par(xpd=T)
legend
to create a legend below the x-axis. i used the parameter horiz=T.
now i would like to put the elements of the legend in two rows:
e.g. if my legend has got 5 elements, i would like 3 elements in one row
and the last two elements in the next row.
does anyone know how to do that?
Example:
bp<- barplot(1)
par(xpd = TRUE)
legend(bp, 0, xjust=0.5, legend=letters[1:5], lwd=1:5, ncol=3)
