pfw_zerofill {PFW} | R Documentation |
Zerofill Species not Detected in each Survey Instance for Analysis
Description
This function adds zeros for checklists where selected species were absent, setting HOW_MANY = 0 for presence/absence-based analyses. Note that zerofilling entire, unfiltered datasets from Project FeederWatch will take a long time!
Usage
pfw_zerofill(data)
Arguments
data |
A Project FeederWatch dataset, optionally filtered for species. |
Value
A dataset with zerofilled values included for each species.
Examples
## Not run:
# This example cannot be run because it relies on a cached version of the
# data which is created upon using pfw_import(). Storing a version of this
# for the example dataset would be too large for CRAN!
# Zerofill a PFW dataset
data_zf <- pfw_zerofill(data)
## End(Not run)
