How do I resize the treemap output in R

r, treemap

Solution

You can set the `width` and `height` of your graphical device. You could for example do:

png(filename="tree.png",width=800, height=800)
treemap(xlFile, 
        index=c("Code1", "Code2"), 
        vSize="size", 
        vColor="ID", 
        type="value", 
        fontsize.labels=c(14,7))
dev.off()

You can look at this page if you want the output in another format or if you want to look at more options.

Problem

I'm using Martijn Tennekes's treemap package (version 2.2) in R (version 3.1.2) using RStudio (version 0.98.1091). It's working great but there's one thing I'd like to do - resize the output. My call looks like this: ``` treemap(xlFile, index=c("Code1", "Code2"), vSize="size", vColor="ID", type="value", fontsize.labels=c(14,7)) ``` It generates a very small treemap. The aspect ratio is fine (and changing that parameter doesn't change the output dimensions). I would just like to make the whole treemap output larger. The documentation says the treemap can be zoomed in/out, but I'm not sure that'll help - I want to change the output file, not just the view. Thank you. John
