posixct - Calculate time difference between two events (given date and time) in R -


I am currently struggling with the initial issue of calculating the difference of time between the two incidents.

I want to take a column that includes the date and time (both values ​​in a column) and same with ID (A or B) of the value of the previous / next line Together, want to calculate a time difference. ID = C ("A", "A", "B", "B") Time = C ("08.09.2014 10:34", "12.09") 

  .2014 09 : 33 "," 13.08.2014 15:52 "," 11.09.2014 02:30 ") D = Data. Frame (id, time)

My desired output is time in the format : Minute 

  time difference = c ("94: 59", "9 4:59", "682: 38", "682: 38")

format day: hours: minute or anything else will work, as long as it can be conveniently implemented I am flexible about the format of the output, the only one above is the idea above Cross my mind

For each single ID, I always have two rows (in Example 2xA and 2xB) I do not have a smart idea to avoid the repayment of the difference.

I have tried some examples before, which I found on StakeVareflow. Most of them used the POSIXt and striptime . Not manage to implement on my data set

dplyr 

  Library (DEPUTOR) D% & gt;% Mute (time = as.paceXct (time, format = "% d.% M% Y% H:% M"))%)% & gt;% )% & Gt; % Mutate (diff = paste0 (gsub ("[.]. *", "", Diff (time) * 24), ":", round (as.numeric (gsub (". *. [.]]," " , Difference (time) * 24)) * 60) # Source: Local data frame [4 x 3] # Groups: ID # # ID time difference # 1A 2014-09-08 10:34:00 94: 59 # 2A 2014-09-12 09:33:00 94:59 # 3b 2014-08-13 15:52:00 682: 38 # 4b 2014-09-11 02:30:00 682: 38

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
