times in data frame recorded integers in: 1005,1405,745,1130,2030 etc. how convert these integers r understand , use in functions such strptime. in advance help solution using strptime() as pointed out psidom in comment, can convert integers character , use strptime() : int_times <- c(1005,1405,745,1130,2030) strptime(as.character(int_times), format="%h%m") ## [1] "2016-04-21 10:05:00 cest" "2016-04-21 14:05:00 cest" na ## [4] "2016-04-21 11:30:00 cest" "2016-04-21 20:30:00 cest" however, can see, run trouble number has 3 digits. can around using formatc() format integers character 4 digits , leading 0 (if needed): char_times <- formatc(int_times, flag = 0, width = 4) char_times [1] "1005" "1405" "0745" "1130" "2030" now, conversion works: strptime(char_times, format="%h%m") ## [1] "2016-04-21 10:05:00 cest" ...

"select departments sum(case when year(employment_date) = '1990' 1 else 0 end) '1990'," + "sum(case when year(employment_date) = '2010' 1 else 0 end) '2010'," + "sum(case when year(employment_date) = '2011' 1 else 0 end) '2011'," + "sum(case when year(employment_date) = '2012' 1 else 0 end) '2012'," + "sum(case when year(employment_date) = '2013' 1 else 0 end) '2013'," + "sum(case when year(employment_date) = '2014' 1 else 0 end) '2014'," + "sum(case when year(employment_date) = '2015' 1 else 0 end) '2015'," + "sum(case when year(employment_date) = '2016' 1 el...

i have "orders" table holds totals in each row every order in shop. need count totals every single row grand total. how set query in laravel? my orders table: my function: public function index() { // orders in db $orders = order::all(); // doesnt work, counts rows $count_total = db::table('orders')->select('count(total)')->count(); dd($count_total); // carts in db $carts = cart::all(); return view('admin.pages.index', compact('orders', 'carts', 'count_products')); } you can use eloquent way, doing can total sum of column. $total = orders::sum('total'); echo "<pre>"; print_r($total); echo "<pre>";

i need create array of size 500, , data randomly distributed , i'm confused how sort array. can me, please? the code random: import java.util.random; public class sorttest { public static void main(string[] args) { // create instance of random class random number generation random random = new random (1l); // begin new scope { // create int array of 500 elements int[] dataarray = new int[500]; // populate array randomly generated values (int index = 0; index < 500; index++) dataarray[index] = random.nextint(); // end scope } } } do need use arrays.sort(dataarray)? or arrays.sort(dataarray, collections.reverseorder())? heard said not primary class. please help!!! thank you!! here should steps: create 500-element integer array using random class’s nextint() method make copy of array , use parameter sort methods (array passed reference). measure execution time sort 500-element array...
