i'm trying understand why different results when print values of list when access them index or directly: ws <- c(as.date('2016-01-01')) (w in ws) { print(w) } # prints 16801 (idx in 1:length(ws)) { print(ws[idx]) } # prints 2016-01-01 i'm not sure why first time, when access value using in wrong value. how can print values directly accessing via in (not using indexes)? , why happening? probably because ws integer; "date" see printing purposes, data tracked days since starting point. when create indexing variable w in ws , r coercing integer w has lost "date" attributes, , underlying integer. indeed, in ?control see seq : an expression evaluating vector (including list , expression) or pairlist or null. factor value coerced character vector. and as.vector(ws) return ws it's underlying, integer, state. in second example, ws has remained unchanged, printing elements continue formatted dates.

i have python list a = [1, 2, 3, 4] and i'd range of indices such if select indices 0 through n , i'm getting (for n=10 ) repeated [1, 2, 3, 4, 1, 2, 3, 4, 1, 2] i of course repeat list via (int(float(n) / len(a) - 0.5) + 1) * a first , select range [0:10] out of that, feels rather clumsy. any hints? you can use modulo operator when accessing list, i.e. a[i % len(a)] this give same result, doesn't require store redundant elements.

converting excel file (where works fine), have sumifs formula returning error "array arguments sumifs of different size". formula in question looks this: =sumifs($g9:$ea9,$f$2:$dz$2,">=1/1/"&a$2,$f$2:$dz$2,"<=12/31/"&a$2) the array arguments are: g9:ea9 - 125 columns, 1 row f2:dz2 - 125 columns, 1 row f2:dz2 - 125 columns, 1 row the criteria arguments values. i'm not looking workaround or hack - want know if i'm somehow misusing sumifs formula can maintain consistency excel this turns out quirk of google sheets, generates many columns "needed". while excel understands ea means when there's no content there, default google sheets thinks there far fewer columns, , therefore offset array ranges indeed different sizes. 38 vs 39 in case. when added 125 columns sheet, formula worked fine.

i know raspberry pi 0 supports otg , usb peripheral protocols, , there's lot of cool built in peripherals shown here: https://learn.adafruit.com/turning-your-raspberry-pi-zero-into-a-usb-gadget?view=all#other-modules the problem need emulate usb peripheral device not appear on list. have vendor id , product id device, , i'm trying figure out how go doing this. need modify otg usb drivers in raspbian kernel? have build own kernel? or there better option don't realize? thanks in advance!! do need modify otg usb drivers in raspbian kernel? the answer first question "it depends", if device doesn't unusual no: need not modify source code kernel modules nor kernel. you're fortunate raspbian supports modern kernel configfs support. once set dtoverlay=dwc2 , can open functionfs bulk endpoint root so: modprobe libcomposite modprobe usb_f_fs cd /sys/kernel/config/usb_gadget mkdir -p myperipheral; cd myperipheral echo 0x1234 > idvendor

is possible link 1 tab nested view in tab? i've tried 2 different methods , neither seem work. here's router config: .config(function($stateprovider, $urlrouterprovider) { // ionic uses angularui router uses concept of states // learn more here: https://github.com/angular-ui/ui-router // set various states app can in. // each state's controller can found in controllers.js $stateprovider // setup abstract state tabs directive .state('tab', { url: '/tab', abstract: true, templateurl: 'templates/tabs.html' }) // each tab has own nav history stack: .state('tab.dash', { url: '/dash', views: { 'tab-dash': { templateurl: 'templates/tab-dash.html', controller: 'dashctrl' } } }) .state('tab.chats', { url: '/chats', views: { 'tab-chats': { templateurl: 'templates/tab-chats.h

i'm working images have text. problem these images receipts, , after lot of transformations, text lost quality. i'm using python , opencv. trying lot of combinations of morphological transformations doc morphological transformations , don't satisfactory results. i'm doing right (i'll comment i've tried, , let uncommented i'm using): kernel = np.ones((2, 2), np.uint8) # opening = cv2.morphologyex(img, cv2.morph_open, kernel) # closing = cv2.morphologyex(img, cv2.morph_close, kernel) # dilation = cv2.dilate(opening, kernel, iterations=1) # kernel = np.ones((3, 3), np.uint8) erosion = cv2.erode(img, kernel, iterations=1) # gradient = cv2.morphologyex(img, cv2.morph_gradient, kernel) # img = erosion.copy() with this, original image: i this: it's little bit better, can see. still bad. ocr (tesseract) doesn't recognize characters here well. i've trained, can note, every "e" different, , on. i results, think, if resolve pr

i want debug function below. print_r nor echo not displaying though. how can print contents of: $order or $paypal_args ? function custom_override_paypal_email1( $paypal_args, $order ) { print_r($paypal_args); print_r($order); // die(); global $woocommerce; foreach ( $order->get_items() $product ) { $terms = get_the_terms($product['product_id'],'product_cat'); if (!is_null($terms)){ if(count($terms)>0) { //get first 1 $term = $terms[0]; if(strtolower($catname)==='ethics'){ $paypal_args['business'] = "zzz@zzz.example.com"; } else{ // $t = strval($term); $paypal_args['business'] = $t ."yyy@yyy.example.com"; } }

i have code , want make scoped. found not working , seems possible through in module. wasn't able find proper question , possible scope constructor injection? does not work @appscope @inject public stackoverflow() { } scope works!! @module public internetmodule { @appscope @provides public stackoverflow providestackoverflow() { return new stackoverflow(); } } you need put scope on class @appscope public class blah { @inject stackoverflow stackoverflow; @inject public blah() { } }

i have dataframe , dict. these like, import pandas pd df1 = pd.dataframe({'first':['john','oliver','sarah']}) df1_map = {'john': 'anderson', 'oliver': 'smith', 'sarah' : 'shively'} print (df1) print (df1_map) first 0 john 1 oliver 2 sarah {'oliver': 'smith', 'sarah': 'shively', 'john': 'anderson'} the values of df1['first'] represent key values of dict. i add second column data frame called df1['second'] dict relationship maintained following dataframe, first last 0 john anderson 1 oliver smith 2 sarah shively now, iterate on dataframe values, so, df1['last'] = [ df1_map[i] in list(df1['first'])] i wondering if pandas support vectorized implementation / function can without iterating on rows of df you can map dictionaries values directly keys with: df1['last'] =

i have function foo makes ajax request. how can return response foo ? i tried return value success callback assigning response local variable inside function , return one, none of ways return response. function foo() { var result; $.ajax({ url: '...', success: function(response) { result = response; // return response; // <- tried 1 } }); return result; } var result = foo(); // ends being `undefined`. -> more general explanation of async behavior different examples, please see why variable unaltered after modify inside of function? - asynchronous code reference -> if understand problem, skip possible solutions below. the problem the a in ajax stands asynchronous . means sending request (or rather receiving response) taken out of normal execution flow. in example, $.ajax returns , next statement, return result; , executed before function passed success callback
