r - modify stat_summary to show only a few point -

currently have boxplot below , stat_summary used show quantiles of each distribution text.

group = c( rep(c(1,2),100)   ) r = rnorm(200,50,63) d = data.frame(  group = group,  r = r  ) head(d) ggplot(data = d, aes(factor(group), r)) +    geom_boxplot()    +    stat_summary(geom="text", fun.y= quantile,                aes(label=sprintf("%1.0f", ..y..)),                position=position_nudge(x=0.33), size=3)  

you can see quantiles printed text via fun.y= quantile line of code. how can modify code print median , min , max printing 3 points instead of 5?

i can create function , select quantiles want

ff= function (x) {   return(quantile(x)[1]) } 

and use fun.y= quantile , print want how incorporate fun.y directly in stat_summary call?

thank you.

add fun.args stat_summary follows:

ggplot(data = d, aes(factor(group), r)) +    geom_boxplot()    +   stat_summary(geom="text", fun.y=quantile,                fun.args=list(probs=c(0,.5,1)),                aes(label=sprintf("%1.0f", ..y..)),                position=position_nudge(x=0.33), size=3)
