Adding Number of Observations and R-square to Marginsplot

[Mahmut Coskun]

Hello everyone,
Is there any way to add the number of observations and R² values into the marginsplot command to have plots with these values?
Thank you,
Mahmut

margins allows twoway options, so use the any number of ways to include text in a twoway graph, e.g.,

webuse nhanes2, clear
regress bpsystol agegrp##sex
margins agegrp
 marginsplot, plotopts(text(140 3 "{it:R}{sup:2} = `:di %3.1f e(r2)'")  ///
 text(143 3.12 "{it:N} = `:di %5.0f e(N)'")) scheme(s1mono)
