[R-sig-Geo] tpk files

[Marta Rufino]

Hi Barry,

Thank you so much for your quik reply!
Yep, I tried that... after downloading, changing the name and decompressing
(it becomes 27GB), then I was not able to read it with r.
I will try again then.

Cheers,
M.

PS: now, it is giving me an error:

Error in CPL_read_ogr(dsn, layer, query, as.character(options), quiet,  :
  std::bad_alloc
In addition: Warning message:
In CPL_read_ogr(dsn, layer, query, as.character(options), quiet,  :
  GDAL Error 1: In GetNextRawFeature(): sqlite3_step() : disk I/O error
