Brian, Thanks for the question, this is something that I'll add a note for me to document in the package documentation. To reference a database, there are a couple of approaches: If you only need access to one layer: you'll need to create a layer file which references the data. You should be able to do this from within ArcMap or Pro by right clicking on the layer > Save as Layer File, if it's in your current map, or right click the layer in the Catalog pane and select "Create Layer". Once you've created that layer file, you can reference it directly with arc.open(), and it'll work like any other data source. If you want to access arbitrary layers in your database: instead of creating an intermediary layer file, you can directly reference things from the .sde file. This file is created when you add a database connection, by default it'll end up in your user profile. You can find it from ArcMap for example by right clicking on the database, selecting Properties, the 'Name' field contains the full path to the sde file. You can copy this elsewhere, or reference it directly, using the syntax: r <- arc.open('c:/path/to/my.sde/dbname.layername')‍ The bridge doesn't currently have the underpinnings to figure out the necessary information directly, but either of the above approaches will give you direct access. Let us know if you need anything else. Cheers, Shaun ... View more

Dave, I can reproduce this issue locally. Despite the 64-bit DLLs involved, the memory limit is being capped at what you'd expect for a 32-bit process (2GB). I'm looking into this issue, it looks like its a default value that is being set by R, but it isn't clear to me why that is yet. In the meanwhile as a workaround, you can add this to the top of any scripts you're working with that need more memory: limit.mb <- as.numeric(     gsub("TotalVisibleMemorySize=", "", gsub("\r", "",         system('wmic OS get TotalVisibleMemorySize /Value',         intern=TRUE)[3]))) / 1024 set.limit <- memory.limit(limit.mb)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ That will set the memory available to R to the total memory available on the machine.
