javascript - Is there any difference between `element` and `iElement` in AngularJS? -

-

i using angularjs , jquery, angularjs official tutorial using ielement inject, other tutorial using element, there different? following btn1 , btn2 work, element , ielement wrap jquery.

var app = angular.module('myapp', []);  app.directive('btn1', function () {     return function (scope, element) {         element.click(function () {             $(this).css('background', '#666');         });     }; });  app.directive('btn2', function () {     return function (scope, ielement) {         ielement.click(function () {             $(this).css('background', '#666');         });     }; });

no, there no difference, both 2 variable names. can use name instead of element/ielement el/eleme etc, factor matters in values passed callback in case link callback function passes scope, element, attributes , controllers.

when matters when use environment argument injection used in controller function or in directive function parameter names used injecting parameters

time series - R growth rate calculation week over week on daily timeseries data -

i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
