Extracts variables from multiple eatGADS data bases.
Data can then be extracted from the GADSdat object via
extractData. For extracting meta data from a data base or a GADSdat object see extractMeta. To speed
up the data loading, getGADS_fast is used per default.
Usage
getTrendGADS(
filePaths,
vSelect = NULL,
years,
fast = TRUE,
tempPath = tempdir(),
verbose = TRUE
)Arguments
- filePaths
Character vectors with paths to the
eatGADSdb files.- vSelect
Variables from all GADS to be selected (as character vector).
- years
A numeric vector with identical length as
filePaths.- fast
Should
getGADS_fastbe used for data loading instead ofgetGADS? Using the default is heavily recommended.- tempPath
The directory, in which both GADS will be temporarily stored. Using the default is heavily recommended.
- verbose
Should the loading process be reported?
Details
This function extracts data from multiple GADS data bases. All data bases have to be created via
createGADS. The data bases are joined via rbind() and a variable year is added, corresponding to the
argument years. The GADSdat object can then further
be used via extractData. See createDB and dbPull for further explanation
of the querying and merging processes.
