i have pre-binned frequency table rather large dataset. is, single column vector of bins , single column vector of counts associated bins. i'd r plot histogram of data doing further binning , summing existing counts. example, if in pre-binned data have [(0.01, 5000), (0.02, 231), (0.03, 948)], first number bin , second count, , choose 0.04 new bin width, i'd expect [(0.04, 6179)]. what's fastest , or easiest way in r? looks ggplot2 has answer. library(ggplot2) qplot(bin, data=cbind(bins,counts), weight=counts, geom="histogram")

one of favorite members helgatheviking , gave me solution of previous question remove quantity field cart page specific product attribute . below function given her. add_filter( 'woocommerce_cart_item_quantity', 'remove_cart_item_quantity', 10, 2 ); function remove_cart_item_quantity( $product_quantity, $cart_item_key ){ $cart_item = wc()->cart->cart_contents[ $cart_item_key ]; if( $cart_item['data']->is_type( 'variation' ) ){ $attributes = $cart_item['data']->get_attributes(); // var_dump( $attributes ); if( array_key_exists( 'color', $attributes ) ){ $product_quantity = ''; } } return $product_quantity; } now $product_quantity; return blank string. is possible show name instead of blank. $product_quantity = ''; should replace ? if selected product has color green $product_quantity; should return green. example: $product_quantity = ...

i'm making universal application windows phone 8.1 , have problem code. after textblock value become greater or equal 22, images should become visible. if value less 22 images should invisible. my question: how can visible images after textblock value >="22" this code hide images: private void points_loaded(object sender, routedeventargs e) { int n = 0; bool b = int.tryparse(points.text, out n); datacontext = this; imagevis = (b && n >= 22) ? visibility.visible : isibility.collapsed; } private visibility imagevis; public visibility imagevis { { return imagevis; } set { imagevis = value; raisepropertychanged("imagevis"); } } public event propertychangedeventhandler propertychanged = delegate { }; protected void raisepropertychanged(string propertyname) { propertychanged(this, new propertychangedeventargs(propertyname)); } this code part xaml: <image x:name="hole17img" horizontalalignmen...

so have 2 .net assemblies, 1 wpf other windows service. talk using wcf protobuf.net serializing types. everything working smooth made primitive plugin system loads plugins, both assemblies in project load same plugins intention of sending classes within them on wire. so... 1. wpf app loads, loads plugins (.net dlls) assembly.loadfrom 2. wcf app loads plugins (same .net dlls) assembly.loadfrom 3. both assemblies share dll (object library) explicitly referenced in source code. all types in object library can serialize on 1 end, go on wire , deserialize no problem. types in plugins can serialized on either end, other end throws type not resolved exception when attempting deserialize, though same type. found out problem, shotgun willingness help, have been lot of code show. basically protobuf couldn't load type because didn't exist in load context of application domain. read stuff on msdn had handle appdomain.currentdomain.assemblyresolve event , return corre...
