arc.open error Error in (function (cl, name, valueClass) #66

Closed rmdewan closed 6 years ago

rmdewan commented 6 years ago

My R code looks like: vac <- arc.open("completepath/filename.gdb") and I am getting the following error:

Error in (function (cl, name, valueClass) : assignment of an object of class “numeric” is not valid for @‘.ptr’ in an object of class “arc.workspace_impl”; is(value, "externalptr") is not TRUE

scw commented 6 years ago

@rmdewan the bridge doesn't directly handle workspaces (like a GDB), you'll need to pass in a fully qualified path to a specific datasource (like a feature class residing in the GDB).

Thanks Shaun, Rajiv

@rmdewan No problem, happy to help. I'll make a note that we should provide a more useful error message if you pass in a workspace to arc.open.

Hi Shaun, I am very familiar with R but a complete novice with ArcGIS. Some one sent me this GDB file which I can open in ArgGIS Pro. It is folder with very many files in it of the following kinds: ATX, GDBTABLE, GDBINDEXES, and SPX among a couple of others. I want to extract the lat/log into an R dataset. Which of these should I try to open in arc.open()?

Thanks and sorry for the very newbie question, Rajiv

Try beta release 1.0.1.229-beta it should be more friendly with opening .gdb workspace.

Hi @rmdewan, no problem. File Geodatabases are a collection of files comprising the database. This database can contain many different data sets all within it, but unfortunately as a pure database, you can't immediately tell from the filenames on disk what it contains. If you can open the data in ArcGIS Pro, you should be able to navigate to the GDB, and see the feature class, raster or table names from within the application. Once you see one of those names, you can add it after ".gdb/" and it'll be openable within R.

That is a cool tip Shaun. Thanks Rajiv
