[jira] [Updated] (ARROW-17448) [R] Fix cloud storage paths in some documentation
[ https://issues.apache.org/jira/browse/ARROW-17448?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sam Albers updated ARROW-17448:
-------------------------------
Summary: [R] Fix cloud storage paths in some documentation (was: [R][Python] Fix cloud storage paths in some documentation)
> [R] Fix cloud storage paths in some documentation
> -------------------------------------------------
>
> Key: ARROW-17448
> URL: https://issues.apache.org/jira/browse/ARROW-17448
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python, R
> Affects Versions: 9.0.0
> Reporter: Sam Albers
> Priority: Minor
>
> There are a few issues with the documentation for the cloud storage examples where paths are incorrect. For example in this vignette: [https://arrow.apache.org/docs/r/articles/fs.html]
> This doesn't work:
> {code:java}
> df <- read_parquet(bucket$path("nyc-taxi/year=2019/month=6/data.parquet")){code}
> rather it should be:
> {code:java}
> df <- read_parquet(bucket$path("nyc-taxi/year=2019/month=6/part-0.parquet")){code}
> which I think makes sense as part-0 is the default writing convention for write_dataset and therefore something users are likely to see. Indeed this the way the file structure was written:
> {code:java}
> library(arrow)
> bucket <- s3_bucket("voltrondata-labs-datasets")
> bucket$ls(path = "nyc-taxi/year=2011", recursive = TRUE)
> #> [1] "nyc-taxi/year=2011/month=1"
> #> [2] "nyc-taxi/year=2011/month=1/part-0.parquet"
> #> [3] "nyc-taxi/year=2011/month=10"
> #> [4] "nyc-taxi/year=2011/month=10/part-0.parquet"
> #> [5] "nyc-taxi/year=2011/month=11"
> #> [6] "nyc-taxi/year=2011/month=11/part-0.parquet"
> #> [7] "nyc-taxi/year=2011/month=12"
> #> [8] "nyc-taxi/year=2011/month=12/part-0.parquet"
> #> [9] "nyc-taxi/year=2011/month=2"
> #> [10] "nyc-taxi/year=2011/month=2/part-0.parquet"
> #> [11] "nyc-taxi/year=2011/month=3"
> #> [12] "nyc-taxi/year=2011/month=3/part-0.parquet"
> #> [13] "nyc-taxi/year=2011/month=4"
> #> [14] "nyc-taxi/year=2011/month=4/part-0.parquet"
> #> [15] "nyc-taxi/year=2011/month=5"
> #> [16] "nyc-taxi/year=2011/month=5/part-0.parquet"
> #> [17] "nyc-taxi/year=2011/month=6"

> #> [19] "nyc-taxi/year=2011/month=7"
> #> [20] "nyc-taxi/year=2011/month=7/part-0.parquet"
> #> [21] "nyc-taxi/year=2011/month=8"
