rgdal - read a table within a ESRI geodatabase (gdb)

问题

I am trying to read a table from a ESRI geodatabase (.gdb) that has no geometry using R. readOGR is throwing an error because there is no geometry defined, which kind of make sense:

library(rgdal)

readOGR("gSSURGO_CO.gdb","mutext")
#Error in readOGR("gSSURGO_CO.gdb", "mutext") : no features found
#In addition: Warning message:
#In ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv,  :
#ogrInfo: all features NULL

My current solution is to access directly GDAL and dump a cvs of the table that I read back into R:

# Here example with the same layer
system("ogr2ogr -f CSV mutext.csv gSSURGO_CO.gdb mutext")
mutext <- read.csv("mutext.csv")

It works, but is there a better way to do this?

Thanks!
