r - Reading user input without echoing -

-

i'm wondering if there way can read user input stdin without echoing screen in r. know readline(), readlines() , scan() can read in user input keyboard none appear have option not echo back.

as might expect grab password. i'm looking let me do:

> a<-get_password() password: > [1] "password"

what's operating system? if can run terminal, should work.

get_password <- function() { cat("password: ") system("stty -echo") <- readline() system("stty echo") cat("\n") return(a) }  > <- get_password() password:  > [1] "sdfs" >

this works on os x using r terminal.app, not r.app. no idea on windows solution, since there doesn't seem native r solution.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
