[R] Displaying a summary in graphics
Sent by:
r-help-bounces@r-project.org



I'm writing a script which puts together a bunch of graphs and outputs 
them to a graphics device.   One of the things I want to add is ANOVA 
summaries but I'm having trouble with formatting them for graphics.

I do this:

anova_summary <- summary(aov(concentration~inhibition*genotype, data 
=drug_data))

print(anova_summary)

The printout to the R console is in the format I want but if I do this:

mtext(side=1, outer=TRUE, text=anova_summary, cex=0.75, line=1, adj=0)

I don't get the proper formatting. 

I gather, from the documentation and searching the web, that the issue is 
that summary() includes a method for print() to format the data but 
mtext() doesn't follow the method.  If I understand correctly, I need to 
use something like format() or encodeString() to get the proper formatting 
for mtext() to use.   The thing is that I haven't figured out anything 
close to the right parameters to use.  Is there some place which describes 
how to do this?
