Extracts variables from a eatGADS
data base. Only the specified variables are extracted. Note that this selection determines the format
of the data.frame
that is extracted. CAREFUL: This function uses a local temporary directory to speed up loading the data base
from a server and caches the data base locally for a running R session. The temporary data base is removed automatically when the
running R
session is terminated.
getGADS_fast(vSelect = NULL, filePath, tempPath = tempdir())
Returns a GADSdat
object.
Character vector of variable names.
Path of the existing eatGADS
data base file.
Local directory in which the data base can temporarily be stored. Using the default is recommended.
A random temporary directory is used for caching the data base and is removed, when the R
sessions terminates. See
createDB
and dbPull
for further explanation of the query and merging processes.
