pull stat out of summary

You can get the full explanation (VERY full), at ?Extract or any of its aliases, like ?'$' or ?'['
...and the intermediate answer is: hold["Mean"] -pd

Continuing my learning curve after 25_ years with using SAS. Want to pull the "Mean" forom the summary of something... test <- rnorm(1000,1.5,1.25) hold <- summary(test) names(hold) [1] "Min." "1st Qu." "Median" "Mean" "3rd Qu." "Max." OK, so "Mean" is in there. So, is there a short form answer for why hold$Mean throws an error, and hold["Mean"} returns the mean (as desired)? Silly question I know, but gotta start somewhere... Thanks...
