i have been battling code day trying convert data long wide format. let me explain data set , code used. i have on 2 million rows 700k unique subject(usb), 125 unique days(date, m-d-y format), 83 unique group (grp), kyc , val1. here last code looks based on solution found on stackoverflow: n1 = unique(mydata[,c("usb","date")]) n1$idv = 1:nrow(n1) n2=merge(mydata,n1) dcast(n2,usb + idv ~ grp, value.var="val1"). this worked small portion of data other failed whole data set. i noticed unique(mydata[,c("usb","date","kyc")]) works better small sample , genesis of problem. for privacy reason can not post portion of data. please appreciate suggestion or how fix this. below other examples here have tried no luck library(splitstackshape) out_df <- dcast( getanid( x_df, 'time' ), time~.id, value.var='measure' ) qcc( out_df[,-1], type = 'xbar', labels = out_df[,1] ) i tried :

function a(){} a.prototype = "foo bar"; new a() instanceof a; // typeerror: function has non-object prototype 'foo bar' in instanceof check as can see, if prototype of constructor not object, fail , throw error. there way make sure instanceof not fail? typeof new a().constructor.prototype === "object" and typeof object.getprototypeof(new a()) === "object" apparently not work. the error says a.prototype needs object, should check that: function isobject(x) { return x != null && (typeof x == "object" || typeof x == "function"); } but isobject(a.prototype) not can assert instanceof call won't throw. going spec, should test function allowsinstancecheck(c) { try { if (!isobject(c)) return false; var m = c[symbol.hasinstance]; if (m != null) return typeof m == "function"; if (typeof c != "function") return false; return is

animals = ['lion' ,'tiger', 'lepord', 'cheetah', 'cat'] find = [] name in animals: if name == 'lion': find.append(name) print (find) find = [find.append(name) name in animals if name=='lion'] print (find) the loop output ['lion'] whereas list comprehension ['none'] . why it? the none comes list method append returns none . rather calling append in: [find.append(name) name in animals if name=='lion'] write: [name name in animals if name=='lion']

i'd understand how write thread safe code. for example have code in game: bool _done = false; thread _thread; // main game update loop update() { // if computation done handle start again if(_done) { // .. handle ... _done = false; _thread = new thread(work); _thread.start(); } } void work() { // ... massive computation _done = true; } if understand correctly, may happened main game thread , _thread can have own cached version of _done , , 1 thread may never see _done changed in thread? and if may, how solve it? is possible solve by, applying volatile keyword. or possible read , write value through interlocked 's methods exchange , read ? if surround _done read , write operation lock (_someobject) , need use interlocked or prevent caching? edit 1 if define _done volatile , call update method multiple threads. possible 2 threads enter if statement before assign _done false?
