Subject: Re: [R] adding results to plot

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

as.character(res)

[1] "c(W = 0.992709285275917)"    "0.869917232073854"
[3] "Shapiro-Wilk normality test" "rnorm(100)"

plot(0:1, 0:1); text(0,seq(.1,.9,.2), labels = res, pos = 4)

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
