[Traminer-users] Adding value labels to graphs

[Joel Schwartz]

Hi Florian,

Thanks for your suggestion. Your code places a custom title at the top of each individual plot. I'm actually trying to do something different. I want to add on the plot itself the number of subjects within each subcategory of each bar. For example, looking at page 33 of your paper, let's take the graph in the top left ("OD25 (n=87)") as an example. I want to put a number inside each gray rectangle and inside each blue rectangle equal to the number of subjects represented by each of those rectangles (the other rectangles in your plot are too thin to do this, but in my case I have enough room to add numbers to nearly all the sub-categories of my plot). 

This webpage will give you an idea of what I'm looking for. It's a different type of plot, but it has value labels inside each section of each bar:

Do you know if that's possible in TraMineR?

Thanks again,
Joel

I first opened the graphical device , than defined with par the number of indexplots and the order (mfrow=c(6,2)), i.e. i had two columns containing 6 plots each. Than I defined a vector "pres" comprising the names of my plots. I produced the plots using a loop (somewhat inefficient for R, I guess). In this loop I am defining the title using the "paste"-command as the respective item of the label vector "pres" and the number of the people in my cluster ,sum(clus30m ==j). It is important to not put apostrophs surrounding the latter because R should evaluate it and paste in the number and not the string "sum(clus30m ==j)". The whole thing is time consuming because you have to look and arrange your plots beforehand. However, the result of the syntax looks like P.33ff. of this working paper http://www.diw.de/documents/publikationen/73/diw_01.c.372555.de/diw_sp0374.pdf. I hope this helps.

For journals, it makes more sense to have a certain state symbolized by a pattern for example parallel stripes instead of having it displayed as green. I remember that I could not figure out how to do this. I would be very thankfull for any experience or info on that, whether a respective package exists and whether it works with TraMineR. Again, thanks to all who have contributed and contribute to that package!

The plot area coordinate values seem to run from 0 to 1 on         the y-axis and from -10 to 2 on the x-axis. If I used an x-coordinate less than -2, then no text was added to the plot. Do you know why I couldn't add text to the right side? Also, the x-coordinate values seem a bit odd. Why -12 to 2 (in jumps of 2) for a graph with a sequence length of 7?
