rtry_select_anc {rtry}R Documentation

Select ancillary data in wide table format

Description

This function selects one specified ancillary data together with the ObservationID from the imported data and transforms it into a wide table format for further processing.

Usage

rtry_select_anc(input, ..., showOverview = TRUE)

Arguments

input

Input data frame or data table.

...

The IDs of the ancillary data (DataID in the TRY data) to be selected.

showOverview

Default TRUE displays the dimension and column names of the selected data.

Value

An object of the same type as the input data.

References

This function makes use of the subset and distinct functions within the base and dplyr packages respectively. It also uses the functions rtry_select_col and rtry_remove_col, as well as the function rtry_join_outer to select and combine the extracted ancillary data with the ObservationID.

Examples

# Obtain a list of ObservationID and the corresponding ancillary data of interest
# using the specified DataID (e.g. DataID 60 for longitude and 59 for latitude) from
# the provided sample data (e.g. data_TRY_15160)
georef <- rtry_select_anc(data_TRY_15160, 60, 59)

# Expected message:
# dim:   98 3
# col:   ObservationID Longitude Latitude


# Obtain a list of ObservationID and one corresponding ancillary data of interest
# using the specified DataID (e.g. DataID 61 for altitude) from the provided sample
# data (e.g. data_TRY_15160)
alt <- rtry_select_anc(data_TRY_15160, 61)

# Expected message:
# dim:   23 2
# col:   ObservationID Altitude
