mean.height: Calculate the vegetation height

In nstauffer/dima.tools: Reading, Manipulating, Analyzing, and Visualizing Data from Copies of the Database for Inventory, Monitoring, and Assessment (DIMA)

Description

Calculate the vegetation height

Usage

## S3 method for class 'height'
mean(lpi.tall, by.line = FALSE, tall = FALSE,
  by.year = FALSE, by.max = FALSE, omit.zero = FALSE, ...)

## S3 method for class 'height'
mean(lpi.tall, by.line = FALSE, tall = FALSE,
  by.year = FALSE, by.max = FALSE, omit.zero = FALSE, ...)

Arguments

lpi.tall	A tall/long-format data frame. Use the data frame "height" from the gather.lpi() output.
by.line	Logical. If TRUE then results will be reported further grouped by line using the LineID and LineKey fields from the data forms. Defaults to FALSE.
tall	Logical. If TRUE then the returned data frame will be tall rather than wide and will not have observations for non-existent values e.g., if no data fell into a group on a plot, there will be no row for that group on that plot. Defaults to FALSE.
by.year	Logical. If TRUE then results will be reported further grouped by year using the DateModified field from the data forms. Defaults to FALSE.
omit.zero	Logical. If TRUE the results omit height measurements of {0
