New dataset: A15 Employees, farmholdings, utilized agricultural area and livestock on level 1 of classification by canton

[cmdoret]

Proposal to include dataset: Employees, farmholdings, utilized agricultural area and livestock on level 1 of classification by canton

Dataset properties

• URL: https://www.bfs.admin.ch/asset/en/px-x-0702000000_101
• format: px
• size: 83MB
• dimensions: area type (plain, mountain, hill, ...), canton, year, size class (hectares range), system (organic, conventional, ...), form (part time, full time, ...)
• units: amount of (employees, animals), surface area (hectares)
• lang: en

Additional notes

• The dataset combines indicators representing different things (cattle, employees, are). These need to be spread across different columns.
• Meaning of area types (mountain 1/2/3/4) are not clear and will need to to do one of:
  • recode with more descriptive names
  • combine mountain categories
  • omit area type factor

Questions

[cmdoret]

The dataset is "only" 83MB, but I cannot seem to download it, even when setting it to "large". It is still waiting after 15min.

@cmdoret For that I think we would need another option xlarge for ds$size. pxRRead in that case works better on downloaded files: so the file needs to be downloaded first that parsed and then the doqnload should be removed again.

[cmdoret]

I tried implementing an xlarge option where the file is first downloaded and then parsed:

tmp <- paste0(tempfile(), ".px")
download.file(ds$read_path, tmp)
df <- pxRRead::scan_px_file(tmp,
  locale = ds$lang,
  encoding = ds$encoding
)
ds$data <- df$dataframe

But the pxRRead::scan_px_file hangs for 10+ minutes at:

INFO [2023-08-04 11:15:54] unsupported keyword detected DATASYMBOL5[en]
INFO [2023-08-04 11:15:54] unsupported keyword detected DATASYMBOL6
INFO [2023-08-04 11:15:54] unsupported keyword detected DATASYMBOL6[fr]
INFO [2023-08-04 11:15:54] unsupported keyword detected DATASYMBOL6[en]

After investigation, it appears the culprit is pxRRead::parse_px_lines. The file contains ~1M lines and parsing them is pretty slow. I have open an issue on the pxRRead on this topic sdsc-ordes/pxRRead#20

[cmdoret]

Issue addressed upstream in sdsc-ordes/pxRRead#21. The parser can now accommodate huge file. This dataset is parsed in under 1 minute instead of 3h.
