r - Collapse a dataframe -

-

I have a dataID with a sampleID, chromosome, start and stop, and minol score. I want to break the dataframe so that for each possible combination of start.pos and stop.pos, Chrome adds a minol score to all the samnains.

Input: 

  sampleID chrom start.pos end.pos meancol 1.1 0012102_A01 1 0 11,194,349 1 1.4 0012102_A01 1 11,194,349 11,492,125 1.5 1.51212102_A01 1 11,492,125 71,442,329 1 1.9 0012102_A01 1 71,442,329 249250621 1 1.13 0012102_A02 1 0 65493011 1 1,92 0012102_A02 1 65493011 66164733 1 1,102 0012102_A02 1 66164733 121347754 1 1,52 0012102_A02 1 121347754 249250621 0 1,14 0012102_A03 1 56384956 1 1,83 0012102_A03 1 56384956 106266297 1 1,73 0012102_A03 1 106266297 249250621 0 1,15 0012102_A04 1 0 51,484,139 1 1.27 0012102_A04 1 51484139 249250621 0 2.1 0012102_A01 2 50000001 1 2.2 0012102_A01 2 50000001 250000001 1 2.3 0012102_A02 2 50000001 0 2.7 0012102_A02 2 50000020 270000001 0 2.18 0012102_A03 2 50000004 2.19 0012102_A03 2 50000004004 250000001 0 1.15 0012102_A04 2 0 51,484,139 0 1.27 0012102_A04 2 51,484,139 249,250,621 0

production: here means everything from a sampleID points all Nbv start.pos and each chromosome end.pos has been added to the combination. 

  chrome Startkpos Andkpos Meankl 1 0 11194349 4 1 11194349 11492125 3 1 11492125 51484139 4 1 51484139 56384956 3 1 56384956 65493011 3 1 65493011 66164733 1 1 66164733 71442329 3 1 71442329 106266297 2 1 106266297 121347754 1 1 121347754 249250621 1 2 0 50000001 1 2 50000001 50000004 0 2 50000004 50000020 0 2 50000004 51484139 0 2 51484139 249250621 0 2 249250621 250000001 0

line of the input, for example, : 

  sampleID gives chrom start.pos end.pos meancol 1.1 0012102_A01 1 0 11,194,349 1

production amount for this area points in all Nmunaids: 

  chrome start.pos end.pos meancol 1 0 11194349 4

I'm not completely clear Here's what your criteria are for "overlap". You comment that, for chromosome 1, the range (0,11194349) appears in four rows: 1.1, 1.13, 1.14 and 11.15. Fair enough But you believe that limit (65493011,66164733) is only once appeared also appear in this border lines: 1.5, 1.92, 1.83, and 1.27 (a sum ( Meancol) = 3 ). So either I can not understand your criteria, or there are errors in your example

Below the latter, here in FoolLope (...) .table is a method by using the package (> = 1.9.4). As.data.table (DF) # df setkey has assumed its data (dt, chrom, start.pos -;

Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested. The request was sent to the server, which is the compressed log files, perform some database operations and returns a compressed file. After just 2 minutes, 504 gateway time-out server did not respond timely message on browser net panel How to fix this error?

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. ...
