[EXT] Re: adding results to plot
This is pretty kludgy but ... res.p <- capture.output(res) ? # creates a list of what goes to the screen res.pl <- '' "?? # initialize res.pl res.nul <- sapply(res.p,function(x.c) res.pl <<- paste(res.pl,res.c,sep='\n'))? # adds the list items separated by a line feed text(x, y, res.pl, pos=4, cex=mycex) This will replicate the print object for the t.test that goes to the screen so you can add it to a plot. One note, the output of several lines will be left justified at the x-location but centered vertically on the y-location. Experimental with the cex setting to fit it on your plot. It will also put two blank lines above and one below so you might strip those out for better positioning Best regards David Stevens

I was wrong. text() will attempt to coerce to character. This may be informative:

res is a list of class "htest" . You can only add text strings to a plot via text(). I don't know what ggplot does.

Dear all I know I have seen the answer somewhere but I am not able to find it. Please help
plot(1,1) res <- shapiro.test(rnorm(100)) res
Shapiro-Wilk normality test data: rnorm(100) W = 0.98861, p-value = 0.5544 I would like to add whole res object to the plot. I can do it one by one
text(locator(1), res$method) text(locator(1), as.character(res$p.value))
... But it is quite inconvenient I could find some way in ggplot world but not in plain plot world. Best regards Petr
