generating a bar chart with two axis for co-linear variable
Hello Dimitris, I was goggling for some help on Sensitivity vs 1-specificity and saw your link. 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 -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
