Description
Temporary vector with zero values
Usage
1
blank_col(taxon, wide.df)
Arguments
taxon
The name of the taxon necessary for calculating a metric but
is not found in the data set.
wide.df
Taxonomic counts aggregated at the appropriate taxonomic
rank in a wide data format. Use the wide function to prepare the data.
Value
Creates a temporary vector containing zero values the length of the
data frame specified by the object taxa.rank. Prevents errors created by missing taxon names
necessary for metric calculations. For example, if no Trichoptera taxa were observed
in the data set then there would be no column named "Trichoptera" in the wide order
taxa.rank data frame. When metrics, such as pct_ept or pct_trichoptera, search for a column
named "Trichoptera" a null value is returned and the function fails. Therefore,
this function temporarly fills the missing columns with zeros and the metric
can be calculated.
