count_summary function

Compute a summary of counts

Summarize counts over a trim input dataset. Sites without counts are removed before any counting takes place (since these will not be used when calling trim). For the remaining records, the total number of zero-counts, positive counts, total number of observed counts and the total number of missings are reported.

count_summary(
  x,
  count_col = "count",
  site_col = "site",
  year_col = "year",
  eps = 1e-08
)

Arguments

• x: A data.frame with annual counts per site.
• count_col: [character|numeric] index of the column containing the counts
• site_col: [character|numeric] index of the column containing the site ID's
• year_col: [character|numeric] index of the column containing the year
• eps: [numeric] Numbers smaller then eps are treated a zero.

Returns

A list of class count.summary containing individual names.

Examples

data(skylark)
count_summary(skylark)

s <- count_summary(skylark)
s$zero_counts # obtain number of zero counts
