test <- geojsonio::geojson_read( "https://opendata.arcgis.com/datasets/d49160d2e5af4123b15d48c2e9c70160_4.geojson")

produces Error in unlink(x) : file name conversion problem -- name too long?

The file downloads OK using download.file. Given short name EW.geojson and then attempting to read in locally produced the same error message.

thanks @HywelMJ having a look

[sckott]

what were you trying to get as the output?

[HywelMJ]

I'm not sure I understand your question so forgive me if my responses seem odd. The file downloads but geojson_read still suggests 'name too long?' even when the name has been changed to a very short name - 'EW.geojson'. (Actually, I should have thought of checking the length of the path name. That could be pretty long on my PC.)

But surely "https://opendata.arcgis.com/datasets/d49160d2e5af4123b15d48c2e9c70160_4.geojson" isn't too long?

[HywelMJ]

Sorry but I can't reproduce the problem myself now so best close the issue. Sorry to have wasted your time.

[HywelMJ]

More apologies. Problem reproduced using https://opendata.arcgis.com/datasets/e1ed938a33cf472fa802d99b1900164b_1.geojson

[sckott]

I meant: Do you want an R list? json? an sf object? something else?

[HywelMJ]

Now I understand you. My issue is with the error message obtained when using the default setting of geojson_read - which includes 'what = list'. Changing from the default to 'what = "sp"' does work.

[sckott]

Sounds like you do want a list, but you did not say so explicitly, we'll go with a list then.

I'm having a look at the error still.

[sckott]

fiddling with geojson_read on the geojson_read_fixes branch - have to come back to this a bit later as we need to submit a new version fixing other things by tomrrow
