.... hi got issues running ggplot2, i'm trying through basic online tutorial issue, trying run qplot in 1 of exercises got errors listed above, i've read around bit on previous lookups, went through motions of:

  • install.packages("proto")
  • install.packages('ggplot2', dep = true),
  • rebooting r - still getting error. other "answer"?

@mlavoie, mike wise

i had same error after installing ggplot2. 2 ways around this:

1) need load "library(ggplot2)" before call qplot()

library(ggplot2) qplot(factor(class), volume, data = abalone, geom = "boxplot")

2) discovered randomly adding "ggplot2::" in front of code makes work, without calling library.

ggplot2::qplot(factor(class), volume, data = abalone, geom = "boxplot")

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other.
