How do I use qqplot with r -f -

-

i have little script

library(ggplot2)  print(qplot(1:10, 1:10))  readlines("stdin", n = 1)

that trying run with

r -f littlescript.r

unfortunately, expected plot not displayed. in fact, nothing displayed @ all. understand should use print() on qplot()'s output, yet, doesn't in case.

when running script, r doesn't invoke graphics default.

you can add command x11() enable it:

library(ggplot2) x11() print(qplot(1:10, 1:10))  readlines("stdin", n = 1)

alternatively save plot adding call jpeg/pdf etc etc:

library(ggplot2) jpeg("myfilepath.jpg") print(qplot(1:10, 1:10)) dev.off() readlines("stdin", n = 1)

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
