cluster analysis - clustering on geo points using R -

-

i have set of lat, long points city. want cluster these points based on 500m radius or 1km radius using r. precisely, want find find out centroids points within 500m radius particular cluster.

ps:

1.i have used k means. cant fix radius in k - means. 2. tried using leadercluster package in r. after map clusters points, , find distance centroid, found out there lot points tagged cluster more specified radius in leadercluster package.

my question 1 in link: https://gis.stackexchange.com/questions/146701/convert-eps-to-geographic-distance-using-dbscan looking r solution

please suggest nice way cluster these points based on radius.

thanks in advance

use hierarchical clustering.

with maximum linkage, cut @ desired height, can ensure maximum distance in each cluster.

with centroid linkage, distance center should bounded, may limited euclidean distances?

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
