मेरा डेटाफ्रेम इस तरह दिखता है: 

  x1 & lt; -c ("a", सी ("बी", "सी", "जी", "कश्मीर") x3 & lt; - c ("b", "d", "h") "c", "f", "j" (एनए) x4 और एलटी; - c ("ए", "ई", "आई", एनए) डीएफ & एलटी; - डेटा.फ्रेम (x1, x2, x3, x4, स्ट्रिंग्सएफ़एक्टर्स = एफ) डीएफ x1 x2 x3 x4 1 Abba 2 ccde 3 fghi 4 jk & lt; NA & gt; & LT; एनए & gt;

अब मेरे पास एक मनमाना वेक्टर है: 

  vec & lt; - c ("a", "i", "s", "t" "Z")

मैं डेटाफ़्रेम में प्रत्येक पंक्ति के साथ सदिश मानों की तुलना करना चाहूंगा और एक अतिरिक्त कॉलम बनाऊं, जो इंगित करता है कि कम से कम एक वेक्टर मान पाया गया था या नहीं। / P>

परिणामी डेटाफ्रेम इस तरह दिखना चाहिए: 

  x1 x2 x3 x4 मूल्य 1 एबा 1 1 2 सीसीडी 0 3 एफजी 1 4 जेके & lt; NA & gt; & LT; एनए & gt; 0

मैं बिना पाशन के लिए करना चाहता हूं। आपके समर्थन के लिए बहुत-बहुत धन्यवाद!

यहाँ एक तरीका है {1} फ़ंक्शन (x) {यदि (किसी भी (x% में% vec)) {1} अन्य {0}}) लागू करें: 

  df $ valueFound & lt; # & Gt; डीएफ एक्स 1 एक्स 2 एक्स 3 एक्स 4 वैल्यूफ़ाउंड 1 ए बी बी ए 1 सी 2 सी डी ई ई 3 एफ जी एच आई 1 4 जे कश्मीर एलटी; एनए & gt; & LT; एनए & gt; 0

डेविड एरिरबर्ग और @ कैथ के लिए धन्यवाद, जो कुछ अधिक संक्षिप्त दृष्टिकोण हैं:

  • लागू करें (df, 1, function (x) ) किसी भी (x%% vec) + 0)
  • लागू करें (df, 1, function (x) as.numeric (any (x% in% vec))) बस कुछ मज़ेदार मज़े के लिए:
    • लागू (डीएफ, 1, फ़ंक्शन (x) कोई भी (% X%% vec में)% /% TRUE)
    • लागू करें (डीएफ, 1, फ़ंक्शन (एक्स) कमप्रोड (कोई भी (x%% vec)))

apache - 504 Gateway Time-out The server didn't respond in time. How to fix it? -

Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
