site_timeline: Create a Timeline of Site(s) that Meet Criteria

Description

Creates a ggplot2 plot of all sites that meet the user-specified site code (i.e., three letter abbreviation) and/or habitat criteria. See lter_sites for the full set of site information including accepted site codes and habitat designations (unrecognized entries will trigger a warning and be ignored). Lines are grouped and colored by habitat to better emphasize possible similarities among sites

Usage

site_timeline(sites = NULL, habitats = NULL, colors = NULL)

Value

(ggplot2) plot object of timeline of site(s) that meet user-specified criteria

Arguments

sites

(character) three letter site code(s) identifying site(s) of interest

habitats

(character) habitat(s) of interest. See unique(lter_sites$habitat)

colors

(character) colors to assign to the timelines expressed as a hexadecimal (e.g, #00FF00). Note there must be as many colors as habitats included in the graph

Examples

# Make the full timeline of all sites with default colors by supplying no arguments
site_timeline()

# Or make a timeline of only sites that meet certain criteria
site_timeline(habitats = c("grassland", "forest"))
