问题 I would like to read spatial data into R from my Oracle Spatial database. When I execute ogrDrivers() I do not see anything for Oracle Spatial. And the following fails: > require(rgdal) > ogrInfo(dsn="OCI:myusr/mypwd@mydb:MYTABLE:") Error in ogrListLayers(dsn = dsn) : Cannot open data source It looks like Oracle Spatial driver is not normally built into OGR (Oracle makes it really difficult for everybody to work and interoperate with other eco-systems!). I am wondering whether there are other

问题 The data I have two shapefiles marking the boundaries of national and provincial electoral constituencies in Pakistan. The objective I am attempting to use R to create a key that will generate a list of which provincial-level constituencies are "contained within" or otherwise intersecting with which national-level constituencies, based on their coordinates in this data. For example, NA-01 corresponds with PA-01, PA-02, PA-03; NA-02 corresponds with PA-04 and PA-05, etc. (The key will

It keeps saying configure: error: proj_api.h not found in standard or given locations. . The installation code and output is below. Do you

问题 I'm trying to read in a .gdb file using rgdal:: readOGR. I finally got it to work a few days ago by removing the trailing "/" at the end of the path and the .gdb at the end of the file name. Then, poof! today my code won't work. As far as I can tell nothing has changed! After my code failed, I tried updating everything, so I'm now running: Mac OS10.14.4, RStudio v1.2.1335, R v3.6.0, and rgdal v1.4-3. I've checked that rgdal has the OpenFileGDB driver. I've also tried adding the .gdb extension
