getGADS_fast {eatGADS}

Get data from GADS data base fast from server directory.

Description

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.

Usage

getGADS_fast(vSelect = NULL, filePath, tempPath = tempdir())

Arguments

vSelect

Character vector of variable names.

filePath

Path of the existing eatGADS data base file.

tempPath

Local directory in which the data base can temporarily be stored. Using the default is recommended.

Details

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.

Value

Returns a GADSdat object.
