{arcgislayers} in case you want to use arcgis hub data in the future :)

This analysis was super cool! I noticed you hand crafted and processed Feature Layer queries :)

In case you want to use data like this in the future you can make it a little bit easier by using the arcgislayers package!

library(arcgis)
#> Attaching core arcgis packages:
#> → arcgisutils v0.2.0.9000
#> → arcgislayers v0.2.0

# create a reference to the feature layer
cherry_blossoms <- arc_open(
  "https://services2.arcgis.com/j23KFYd23hRWewtZ/arcgis/rest/services/CHERRY_BLOSSOM_DATA_FINAL/FeatureServer/0"
)

# read all features as sf in parallel
all_trees <- arc_select(cherry_blossoms)

# preview
head(all_trees)

OMG thank you. I did not know this existed. How long has it been around?? I've been manually pulling from the API in R for years 😮

[JosiahParry]

Unofficially for like 6-8 months. But "officially" like a week and a half ;)

[hrecht]

Haha okay that makes me feel a lot better, I wrote this code more than a week and a half ago. Definitely will use it in the future.

[hrecht]

Not the right place for this question but - I see the documentation says arcgislayers requires [arcgisutils](https://github.com/R-ArcGIS/arcgisutils) for authorization. - do we need an auth token just for reading from the API? I don't actually have an account myself, I don't publish to ArcGIS, just pull data.

[JosiahParry]

Feel free to strike up a convo at https://github.com/R-ArcGIS/arcgislayers/discussions/ if you want :)

But, no. You definitely do not need a token. That is only for reading content that is privately shared. anything that is publicly available doesn't need a token.

A token would be used for publishing, though, for example

[hrecht]

I ran the code and it worked like a charm, thanks again. So much nicer than my initial code. I'll open a proper issue for the token documentation!
