QString causes Core Dump in App with JNI - qt
I am trying to run the complex application with JNI on 64-bit linux machine and it causes core dump.
Seems it crashes in C++ part of code. I localized the issue, but can't figure the reason out.
I have in my project.cc
...
namespace someNamespace
{
const QString PROJECT_ROOT_TAG = "Project";
Project::Project()
{
m_projectXml = QDomDocument(PROJECT_ROOT_TAG);
...
}
....
}
So, here PROJECT_ROOT_TAG is being corrupted. If I am passing "Project" to QDomDocument, application works fine, even if I am changing QString to char * it works fine, also if I am initializing PROJECT_ROOT_TAG in the constructor in the constructor, instead of global scope, it works... moreover, in the global scope there are other QString initializations also, and if I am doing one of mentioned workarounds with PROJECT_ROOT_TAG, others are just work fine.
I will thankful for any hint or information, which can help me to figure out memory corrucpyion reason.
I am adding hs_err_pid30056.log output also. Hope there is enough information to understand the problem:

How to make this graph (heat map like) which represents bat activity during the year depending on the time of night
I'd like to make this graph on R: Bat activity during the year regarding the time of the night. Each yellow dot is an individual. Blue curves are the sunset and sunrise during the year This is the plot: My excel file looks like this. Date Sunrise Sunset Hours_after_sunset 16/08/2020 06:34 20:56 01:05 17/07/2020 05:53 21:42 01:26 11/08/2020 06:27 21:05 02:17 30/09/2020 07:42 19:20 06:45 24/04/2020 06:31 20:49 05:01 01/07/2020 05:38 21:53 04:13 18/07/2020 05:54 21:41 01:42 04/08/2020 06:17 21:18 01:47 13/08/2020 06:30 21:02 05:14 30/06/2020 05:37 21:53 01:37 15/08/2020 06:33 20:58 01:22 04/09/2020 07:03 20:17 07:25 07/09/2020 07:07 20:11 03:30 28/06/2020 05:36 21:54 02:10 01/07/2020 05:38 21:53 04:13 19/08/2020 06:39 20:50 01:32 09/04/2020 07:01 20:26 07:11 16/05/2020 05:55 21:22 01:14 17/06/2020 05:33 21:52 05:36 22/07/2020 05:59 21:36 03:00 11/08/2020 06:27 21:05 08:42 10/08/2020 06:25 21:07 02:36 08/08/2020 06:23 21:11 07:19 05/08/2020 06:18 21:16 03:33 24/08/2020 06:46 20:40 02:12 16/08/2020 06:34 20:56 04:01 24/08/2020 06:46 20:40 04:18 19/08/2020 06:39 20:50 02:27 22/08/2020 06:43 20:44 05:00 22/08/2020 06:43 20:44 01:56 17/09/2020 07:22 19:49 06:01 Hoping you can help me.

Any solution for this error ?
kamal The crash information you provided is not enough for a diagnosis. As you can see, it reads, "No native Android stacktrace (see debuggerd output)." Could you please share some code, of what you were trying to do? It could be an issue with improper asynchronous programming. To figure out where exactly the app is crashing, you could: Create a System Catchpoint exception, Launch a profiler to track the error, (and should) Use try-catch statements, to basically figure out exactly what line the code is crashing on, & what's the internal stack trace.
Use factors to plot dates out of sequence
I am trying to plot months and days that cross over different years, but not display the year. I can use factors to force the dates to be out of order. If i have a single year of data this code works. but for multiple years i am running into trouble duplicating leap year, and also getting the plot to work.
Error: Column x must be length 1 or 730, not 365
I would like to use the factors to plot the years seasonaly one over the other for each "%m-%d".
Thank you.
dates <- format(seq(from = as.Date("2016-12-01"), to = as.Date("2018-11-30"),
by = "days"), format = "%m-%d")
values = c(rnorm(length(dates)/2, 8, 1.5), rnorm(length(dates)/2, 16, 2))
fDates <- factor(dates, dates)
plot_ly(x = ~fDates, y = ~values, type = "scatter", mode = "lines")
EDIT: This is the desired range for the x-axis. I use the factor to force the levels to conform to this order. I just need to be able to plot multiple years %m-%d against these x axis coordinates.

Troubles in applying the zoo aggregate function to a time series
We have the following function to compute monthly returns from a daily series of prices: PricesRet = diff(Prices)/lag(Prices,k=-1) tail(PricesRet) # Monthly simple returns MonRet = aggregate(PricesRet+1, as.yearmon, prod)-1 tail(MonRet) The problem is that it returns wrong values, take for example the simple return for the month of Feb 2013, the function returns a return -0.003517301 while it should have been -0.01304773. Why that happens? Here are the last prices observations: > tail(Prices,30) Prices 2013-01-22 165.5086 2013-01-23 165.2842 2013-01-24 168.4845 2013-01-25 170.6041 2013-01-28 169.7373 2013-01-29 169.8724 2013-01-30 170.6554 2013-01-31 170.7210 2013-02-01 173.8043 2013-02-04 172.2145 2013-02-05 172.8400 2013-02-06 172.8333 2013-02-07 171.3586 2013-02-08 170.5602 2013-02-11 171.2172 2013-02-12 171.4126 2013-02-13 171.8687 2013-02-14 170.7955 2013-02-15 171.2848 2013-02-19 170.9482 2013-02-20 171.6355 2013-02-21 170.0300 2013-02-22 169.9319 2013-02-25 170.9035 2013-02-26 168.6822 2013-02-27 168.5180 2013-02-28 168.4935 2013-03-01 169.6546 2013-03-04 169.3076 2013-03-05 169.0579 Here are price returns: > tail(PricesRet,50) PricesRet 2012-12-18 0.0055865274 2012-12-19 -0.0015461900 2012-12-20 -0.0076140194 2012-12-23 0.0032656346 2012-12-26 0.0147750923 2012-12-27 0.0013482760 2012-12-30 -0.0004768131 2013-01-01 0.0128908541 2013-01-02 -0.0047646818 2013-01-03 0.0103372029 2013-01-06 -0.0024547278 2013-01-07 -0.0076920352 2013-01-08 0.0064368720 2013-01-09 0.0119663301 2013-01-10 0.0153828814 2013-01-13 0.0050590540 2013-01-14 -0.0053324785 2013-01-15 -0.0027043105 2013-01-16 0.0118840383 2013-01-17 -0.0005876459 2013-01-21 -0.0145541598 2013-01-22 -0.0013555548 2013-01-23 0.0193624621 2013-01-24 0.0125802978 2013-01-27 -0.0050807744 2013-01-28 0.0007959058 2013-01-29 0.0046096266 2013-01-30 0.0003844082 2013-01-31 0.0180603867 2013-02-03 -0.0091473127 2013-02-04 0.0036322298 2013-02-05 -0.0000390941 2013-02-06 -0.0085320734 2013-02-07 -0.0046591956 2013-02-10 0.0038517581 2013-02-11 0.0011412046 2013-02-12 0.0026607502 2013-02-13 -0.0062440496 2013-02-14 0.0028645616 2013-02-18 -0.0019651341 2013-02-19 0.0040206637 2013-02-20 -0.0093543648 2013-02-21 -0.0005764665 2013-02-24 0.0057176118 2013-02-25 -0.0129979321 2013-02-26 -0.0009730782 2013-02-27 -0.0001453191 2013-02-28 0.0068911863 2013-03-03 -0.0020455332 2013-03-04 -0.0014747845 The results of the function is instead: > tail(data.frame(MonRet)) MonRet ott 2012 -0.000848156 nov 2012 0.009833881 dic 2012 0.033406884 gen 2013 0.087822700 feb 2013 -0.023875638 mar 2013 -0.003517301
Your returns are wrong. The return for 2013-01-23 should be: > 165.2842/165.5086-1 [1] -0.001355821 but you have 0.0193624621. I suspect this is because Prices is an xts object, not a zoo object. lag.xts breaks the convention in lag.ts and lag.zoo of k=1 implying a "lag" of (t+1) for the more common convention of using k=1 to imply a "lag" of (t-1).
