How to restart R and continue a benchmark script from previous line (on Windows)?


How to restart R and continue a benchmark script from previous line (on Windows)?

hop of those help? One thing I do for benchmarks like this is to launch another instance of R and have that other R instance return the results to stdout (or simpler, just save it as a file).
Example:
code :
times <- c()
for( i in 1:length(param) ) {
   system(sprintf("Rscript functions/mytest.r %s", param[i]))
   times[i] <- readRDS("/tmp/temp.rds")
}
args <- commandArgs(trailingOnly=TRUE)
NN <- args[1]
allDT <- readRDS("mydata.rds")
...
# save results
saveRDS(myresult, file="/tmp/temp.rds")

Any of those help You shouldn't let the script time out but instead try to process a limited number of items at a time on a specific time interval using a timer trigger.
Well I guess you could answer that this is more easily said than done ... but it is actually very simple :

will help you It isn't possible to do this "automatically", you need to record some notion of the program's state when the computer shuts down. Conceptually this is no different than having the program exit, then running it again and picking up where it left off (without rebooting).
There are a number of different ways to save state, broadly called serialization. In Python, two common options for serialization are the JSON text format and "pickling", which lets you serialize a Python data structure.

I hope this helps . You could break the code into 2 files and write a batch file (.bat) that runs the first file through .rs.restartR() and then the remainder of the code in the next file.
You could also skip the .bat and just schedule both .R scripts to run in Task Scheduler.

wish help you to fix your issue I can't comment to expand on Squashman's suggestion, so let me answer here.
In your case, if you only want to have Pageant running in the background, without interacting with it, I think it's best to run:
code :
START "" /B <your command>

I wish this helpful for you This snippet runs the same script in the new powershell process and exits the older shell.Script scoping was necessary for myinvocation (when called from a funcion) and added an exit function call :-) :
code :
     function checkRights() {
$identity = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$princ = New-Object System.Security.Principal.WindowsPrincipal($identity)
    if(!$princ.IsInRole( `
    [System.Security.Principal.WindowsBuiltInRole]::Administrator))
   {
     $powershell = [System.Diagnostics.Process]::GetCurrentProcess()
     $psi = New-Object System.Diagnostics.ProcessStartInfo $powerShell.Path
      $psi.Arguments = '-file ' + $script:MyInvocation.MyCommand.Path
      $psi.Verb = "runas"
  [System.Diagnostics.Process]::Start($psi) | Out-Null
   return $false
  }
  else{
  return $true
  }
}
$rights = checkrights
$rights
if($rights){
"opened in admin rights"
#for pausing
Read-Host

}else
{
"no admin rights ,trying to open in admin rights"
[Environment]::Exit(0)
}
