R odjitter in Windows

[temospena]

Hi,

In Win 10, there is apparently an error of reading/writing the temporary od_jittered.geojson file.

library(od) #just to get a small data input
library(odjitter)
#> 
#> Attaching package: 'odjitter'
#> The following object is masked from 'package:base':
#> 
#>     jitter

od_all_jittered = odjitter::jitter(
  od = od_data_df,
  zones = od_data_zones_min,
  subpoints = sf::st_sample(od_data_zones_min, 200)
)
#> Warning in system(msg): 'odjitter' not found
#> Error: Cannot open "C:\Users\UTILIZ~1\AppData\Local\Temp\RtmpeWTALa/od_jittered.geojson"; The file doesn't seem to exist.

The error is persistent between runs/data input.

Error: Cannot open "C:\Users\UTILIZ~1\AppData\Local\Temp\RtmpC08uIU/od_jittered.geojson"; The file doesn't seem to exist.

Looks like a quick fix file location issue, will test on my new Windows laptop and report back...

I can reproduce this isse:

od_jittered = jitter(od, zones, subpoints = road_network)
Error: Cannot open "C:\Users\ROBINA~1\AppData\Local\Temp\Rtmp6TXMlr/od_jittered.geojson"; The file doesn't seem to exist.

Update: it seems the odjitter CLI is not working on windows, not a file path issue.

Good news, it's fixed for me 🎉

Heads-up @temospena it was fixed after double checking the installation on PowerShell, I guess there's some issue with the installation, basically R cannot 'see' the odjitter command for some reason. I plan to add a check to see if it has access to that...

[Robinlovelace]

Can you try this Rosa?:

system("odjitter --help")
odjitter 0.1.0
Dustin Carlino <dabreegster@gmail.com
Disaggregate origin/destination data from zones to points

[Robinlovelace]

Pls try reinstalling the R package, you should get a meaningfull message now...

[temospena]

Thanks!

Reinstalled the R package with remotes::install_github("dabreegster/odjitter", subdir = "r") [not in documentation]

You're right, another message shows up!

Although the package is installed and available.

remotes::install_github("dabreegster/odjitter", subdir = "r") [not in documentation]

nevermind, just found it under the r folder! sorry 😅

[Robinlovelace]

Does it work now?

[temospena]

No. In windows I'm facing the same issue. Error in system("odjitter --help", intern = TRUE) : 'odjitter' not found

In ubuntu it works fine.

[Robinlovelace]

That sounds like an issue with the odjitter CLI tool not being installed on PowerShell...

[temospena]

Right! Sorry, it was not clear to me that cargo / odjitter needed to be installed first (never used PowerShell before).
