i'd use summarise_each() apply multiple functions grouped dataset. however, rather apply each function all columns, i'd apply each function particular subsets. realize specifying each column summarise() , have many variables. is there alternate solution either 1) using summarise_each() , deleting unneeded columns or 2) saving group_by() result, performing multiple separate summarise_each() operations , combining results? if not clear, let me know , can try illustrate example code. i suggest following: here apply min function 1 variable , max function other. merge grouping variable. > by_species <- iris %>% group_by(species) start variable want apply min function: min_var <- by_species %>% summarise_each(funs(min), petal.width) min_var source: local data frame [3 x 2] species petal.width (fctr) (dbl) 1 setosa 0.1 2 versicolor 1.0 3 virginica 1.4 then variable want ap

this question has answer here: behaviour of increment , decrement operators in python 6 answers incrementing in c++ - when use x++ or ++x? 10 answers what ++ sign mean in code: for (var i=0; < mystring.length; i++) { alert(mystring[i]); } while (x>y) { alert ("xrules!"); y++; } ++ increment operator saying y++ is same thing saying y = y + 1

i working on facebook app , have little bit of trouble: have index.php , mypopup.php file. hosted on heroku, if matters in way. need when button pressed on index.php page, popup window should appear, content of mypopup.php file, has html form couple of checkboxes , button. now, question how can data popup window (checked items) passed index.php , work data in index.php file? for example: checkbox1 data1 [checked] checkbox2 data2[unchecked] the data related checkbox1 should passed function in index.php you can use javascript this. content show in lightbox. when lightbox done loading, attach event handlers of items want watch in lightbox ( onchange events example). can pass data index.php on back-end using ajax request. also, realized (silly me), if have html form, can change action of form send data index.php instead of mypopup.php. either way work. depends on specifics of data , need it.

how auth0.com authentication feature compared firebase authentication? does auth0.com -free or silver plan- provide authentication feature firebase not provide? thanks there few providers auth0 has aren't available on firebase yet-- namely providers use other oauth. also, rules system available in auth0 can powerful-- writing custom login/user rules using js. you can setup two-factor auth , passwordless login systems auth0, doesn't seem available firebase yet. you can integrate firebase auth0 add-on, allows use both pretty seamlessly. all in all, depends on how far want go user system-- i'd recommend checking out auth0's firebase tutorial , documentation learn more.

i need count bunch of "things" in cassandra. need increase ~100-200 counters every few seconds or so. however need count distinct "things". in order not count twice, setting key in cf, program reads before increase counter, e.g. like: result = cf[key]; if (result == null){ set cf[key][x] = 1; incr counter_cf[key][x]; } however read operation slows down cluster lot. tried decrease reads, using several columns, e.g. like: result = cf[key]; if (result[key1]){ set cf[key1][x] = 1; incr counter_cf[key1][x]; } if (result[key2]){ set cf[key2][x] = 1; incr counter_cf[key2][x]; } //etc.... then reduced reads 200+ 5-6, still slows down cluster. i not need exact counting, can not use bit-masks, nor bloom-filters, because there 1m+++ counters , go more 4 000 000 000. i aware of hyper_log_log counting, not see easy way use many counters (1m+++) either. at moment thinking of using tokyo cabinet external k

okay, i'm making 2d game in unity, , when run code, error: invalidcastexception: cannot cast source type destination type. toastspawn.spawntoast () (at assets/scripts/toastspawn.js:11) the code in file toastspawn.js follows: #pragma strict var toast : rigidbody; var toastspawner : gameobject; function start() { invokerepeating("spawntoast", 3, 1); } function spawntoast() { var toastclone = instantiate(toast, gameobject.find("toastspawner").transform.position, quaternion.identity); toastclone.addforce(vector2 (0,1) * 1000); } i started using unity yesterday, why getting error. :) well, it'd better if take start c# :p although not javascript guy still can see glitches. you instantiating rigidbody instead of gameobject. take gameobject instead of rigidbody, getcomponent of rigidbody object in order apply force. you have toastspawner gameobject why or using gameobject.find? same gameobject. something like, var toast

i've been researching way find keywords if inside of 'p', 'span' or 'blockquote' , replace them link, using domdocument. i've written piece of regex achieves this, rather use domdocument should result in better solution. the code below has 2 main issues, if place &amp; in $html .. crashes because &amp; isn't escaped , can't find way correctly escape &amp; . a smaller issue, not important .. if html invalid domdocument tries correct html , seem unable prevent this. the preg_replace uses array, because dynamically loaded using multiple keywords. $html = ' <blockquote>random random text</blockquote> <p>we match text</p> <p>this sample text</p>'; libxml_use_internal_errors(true); $dom = new domdocument(); $dom->stricterrorchecking = false; $dom->loadhtml(mb_convert_encoding($html, 'html-entities', "utf-8")); $xpath = new domxpath($dom); foreach($xpath-&g

live example: http://plnkr.co/edit/wws3ufb3iz0cai4u2x04?p=preview when "open modal 1" clicked, following error thrown: error: dialog.open expected template or templateurl, neither found. use options or open method specify them. however, modal 2, doesn't use ng-include , works fine. also, if ui-bootstrap-tpls-0.1.0.js included instead of ui-bootstrap-tpls-0.2.0.js , works fine. any ideas? i believe issue result of changing modal directive terminal. means other directives (e.g. ng-include) not processed along modal. here's commit made change: https://github.com/angular-ui/bootstrap/commit/ec796ec2299d03ddfb821e97047c0329f11ab962#src/modal/modal.js i don't know enough know why directive should terminal, 1 easy solution use ng-include child of modal, rather second directive acting on same element. here's mean: <div modal="opened1"> <ng-include src="'modal1.html'"></ng-include> <
