Trying to find networking metrics with R -


i have created directed network in r. have find average degree, think have, diameter , maximum/minimum clustering. diameter longest of shortest distances between 2 nodes. if makes sense anyone, please point me in right direction. have have coded below far.

library(igraph)  ghw <- graph.formula(1-+4:5:9:12:14, 2-+11:16:17, 3-+4:5:7,                       4-+1:3:6:7:8, 5-+1:3:6:7, 6-+4:5:8,                       7-+3:4:5:8:13, 8-+4:6:7, 9-+10:12:14:15,                       10-+9:12:14, 11-+2:16:17, 12-+1:9:10:14,                       13-+7:15:18, 14-+1:9:10:12, 15-+13:16:18,                       16-+2:11:15:17:18, 17-+2:11:16:18, 18-+13:15:16:17) plot(ghw) get.adjacency(ghw)

total number of directed edges

numdeg <- ecount(ghw)

average number of edges per node

avgdeg <- numdeg / 18

how looking @ documentation?

diameter(ghw)

i not sure mean maximum/minimum clustering, maybe this:

range(transitivity(ghw, type="local"))

btw. average number of edges per node wrong, because every edge belongs 2 nodes.

php - regexp cyrillic filename not matches -

i take list of files php glob(."*.pdf") . files have cyrillic names. example: ООО «Рога и копыта» then load company names database , try find them in file names: preg_match("/$firm_name/ui", $file_name, $match); i have problem: firms if $firm_name visually similar $file_name , preg_match says there no match. mb_detect_encoding both variables return utf-8. there problem in file name, or maybe there encoding or something, can not understand, ask help. upd: $file_name='ООО «Рога и копыта»'; preg_match("/... .Рога и копыта./ui", $file_name, $match); as result, ОО «Рога и копыта» , 1 О missing

c# - OpenXML hanging while writing elements -

Image
i have program pulls data database, caches file , exports data multiple formats (excel, excel 2003, csv). i'm using openxml sdk 2.0 excel work. these export processes run in parallel (using parallel.foreach ), , amount of data can pretty large - e.g. csvs 800mb. during these larger exports, i've noticed writing of xml documents hang. instance, if have 8 exporting in parallel, @ point "pause". hang around same point: //this.writer openxmlwriter created worksheetpart. this.writer.writeelement(new cell() { cellvalue = new cellvalue(value), datatype = cellvalues.string }); when happens, pause debugger (vs2013 in case) , notice threads blocking around same portion of code - bit deeper in openxml sdk - stem call openxmlwriter.writeelement . i dug through source using justdecompile didn't find answers. appears there intermediary stream in use writing isolated storage , is, reason, blocking. underlying stream each of these filestream . here screenshot ...

sql - Select Query has unexpected multiple records (MS Access) -

i may tired, can't seem figure out happening. have 2 queries. query 1 has 10 fields. query 2 has 5 fields. fields 1 through 3 same in both queries. trying write select query , simple add field 5 query2 query1 result should query1 additional field (query2.field5). i join first 3 fields both queries , choose select records in query1 , in query2 match. don't know sql, use query designer. expect same number of records have query 1 instead have 3 times or more. can tell me doing wrong. tried reversing joins still seem same records. thanks in advance. here query: the fields in common divisionname , supplierid = vendorid , commodityname . select [part revenue exposed query p1].divisionname, [part revenue exposed query p1].commodityname, [part revenue exposed query p1].suppliername, [part revenue exposed query p1].partnumber, [part revenue exposed query p1].partdescription, [part revenue exposed query p1].bucode, ...
