match_datasets: Data harmonizing for offline data based on Darwin Core terms .

Description

Data harmonizing for offline data based on Darwin Core terms .

Usage

match_datasets(
  datasets,
  country = NULL,
  lats = NULL,
  lons = NULL,
  species = NULL,
  date = NULL,
  verbose = FALSE
)

Value

Harmonized data set with standardized column names foe species names, latitude, longitude, country and dates.

Arguments

datasets

List of offline or online data to be merge. Each offline data set should be given a specific name for identification in the match data set.

country

Indicate the country column names as they appear in the data sets to be merged.

lats

Match the column names for latitude for each data set to be matched. The default latitude name is decimalLatitude. So, indicate the latitude name as it is referenced in all data sets to be matched.

lons

Match the column names for latitude for each data set to be match. The default longitude name is decimalLongitude. So, indicate the longitude name as it is referenced in all data sets to be match.

species

Indicate the species columns as they appear in the data sets to be matched. The default is species, so if the data set doesn't have species as the column name for scientific species names names, indicate the column name here.

date

Indicate the date column names as they appear in the data sets to be matched.

verbose

Messages during data matching. Default FALSE

Details

If a data set being matched has standard columns, namely decimalLatitude, decimalLatutide, and species, then they are not indicated while matching. Otherwise all column names with varying names for the 5 parameters should be indicated.
