Subject: [R] 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
