r - adding a layer to the current plot without creating a new one in ggplot2 -

in basic r can add layers existing plot without creating new one. df <- data.frame(x = 1:10, y = runif(10)) plot(df, type = "l") points(df, add = t) the second line creates plot , third line adds points existing plot. in ggplot2: my_plot <- ggplot(df, aes(x, y)) + geom_path() my_plot my_plot + geom_point() the second line creates plot , third 1 creates plot. can somehow add points existing plot created second line? there add=true in ggplot? the reason want behaviour using ggplot2 in shiny causes blinks in animations. here idea. keep plot reactivevalue , have observer update plot user inputs. then, have observer watch plot data render plot when plot data changes. way long calculations happen before plot data changed, rendering of plot should happen there should little visible interrupt. here example using diamond dataset ggplot2 large enough slow when rendering paths. shinyapp( shinyui( fluidpage( sidebarlayout( ...

sorry all, newbie here.. maybe it's stupid question, read wikipedia , other source still don't answer... are 5g (mobile network article: http://www.fiercewireless.com/tech/story/china-south-korea-commit-5g-leadership-while-japan-and-us-rely-private-effo/2014-06-08 ) , 5ghz ( new wifi http://www.cnet.com/news/5g-wi-fi-802-11ac-explained-its-cool/ ) same? if it's same, how inference in 5g? increase? not same. 5g refers mobile / cellular technology runs on licensed frequency. technology still under research, there's nothing solid yet, seems fcc targeting 24ghz frequencies purpose. same article mentions samsung's research in 28ghz frequency range. 5ghz routers run on 1 (or more) 5ghz unlicensed frequencies. no overlap.

node.js - blocking code in non-blocking http server -
