Removes or flags non-numeric and not available coordinates as well as lat >90, lat <-90, lon > 180 and lon < -180 are flagged.
cc_val( x, lon ="decimalLongitude", lat ="decimalLatitude", value ="clean", verbose =TRUE)
Arguments
x: data.frame. Containing geographical coordinates and species names.
lon: character string. The column with the longitude coordinates. Default = decimalLongitude .
lat: character string. The column with the latitude coordinates. Default = decimalLatitude .
value: character string. Defining the output value. See value.
verbose: logical. If TRUE reports the name of the test and the number of records flagged.
Returns
Depending on the value argument, either a data.frame
containing the records considered correct by the test (clean ) or a logical vector (flagged ), with TRUE = test passed and FALSE = test failed/potentially problematic . Default = clean .
