HI, Not sure if this is what you wanted. pdf("BarplotsNew.pdf") library(plotrix) lst2<-lapply(seq_len(ncol(dat1)),function(i){ Ctdat<- table(dat1[,i]) Ctdat1<-(Ctdat/sum(Ctdat))*100 dat2<-data.frame(Ctdat,Ctdat1,stringsAsFactors=FALSE)[,-3] colnames(dat2)[3]<-"Rel.Freq" dat2[,1]<- as.numeric(as.character(dat2[,1])) with(dat2,twoord.plot(Var1,Rel.Freq,Freq, lylim=c(0,100),rylim=c(0,1000), ylab="Relative Frequency", rylab="Frequency",main=paste("Bar plot:",colnames(dat1)[i],sep=" "), type=c("bar","l"),lcol=2,rcol=4,xtickpos=Var1,xticklab=Var1)) }) dev.off()

I hope you can be of help to me in one of the issue that I am facing in generating combo chart(bar chart and plot). I am a novice and have some difficulty in getting this logic correct. I am give a dataset (I am attaching a sample dataset). I am using a barplot() and passing values for percentage frequency and the corresponding variables. I am struck here, what my function does is only calculate the frequency for the listed variables and not the frequency percentage. Is there a method or a script with which I can pass the frequency percent and the related values as category columns for x axis? I will attach the graphs that I have generated so that you can suggest the better way. Sampledata - Sampledata.txt What my function does to calculate the frequency with category names in X axis - 1.png My requirement is to generate percentage frequency of the variable in y1 and not the frequency itself. 2.png (where x categories are missing) Thanks, Sudha Krishnan ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
