getTrendGADS | R Documentation |
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.
getTrendGADS(
filePaths,
vSelect = NULL,
years,
fast = TRUE,
tempPath = tempdir(),
verbose = TRUE
)
filePaths |
Character vectors with paths to the |
vSelect |
Variables from all GADS to be selected (as character vector). |
years |
A numeric vector with identical length as |
fast |
Should |
tempPath |
The directory, in which both GADS will be temporarily stored. Using the default is heavily recommended. |
verbose |
Should the loading process be reported? |
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.
Returns a GADSdat
object.
