plot_incr_arm: Plot change between readings, by arm

In swmpkim/SETr: Functions for working with Surface Elevation Table (SET) data

Plot change between readings, by arm

Description

Plot change between readings, by arm

Usage

plot_incr_arm(data, set = NULL, threshold = 25, columns = 4,
  pointsize = 2, scales = "fixed")

Arguments

data	data frame (e.g. '$arm' piece of output from 'calc_change_incr()') with one row per faceting variable, and the following columns, named exactly: date, set_id, arm_position, mean_incr. 'mean_incr' should be an already-calculated field of change since previous reading
set	optional SET ID if you only want to look at one SET; default is to graph all SETs
threshold	numeric value for red horizontal lines (at +/- this value); this should be a value that would be a meaningful threshold for incremental change.
columns	number of columns for faceted output
pointsize	size of points you want (goes into the 'size' argument of 'ggplot2::geom_point')
scales	passed to 'facet_wrap'; same fixed/free options as that function

Value

a ggplot object

Examples

incr_set <- calc_change_incr(example_sets)
plot_incr_arm(incr_set$arm)
plot_incr_arm(incr_set$arm, threshold = 5, columns = 1)
plot_incr_arm(incr_set$arm, set = "SET2", threshold = 5)
