plotLongitudinalMTR

Description

Plots a time series of MTR values as a bar plot. For each bar the spread (first and third Quartile) is shown as error bars as well as the numbers of echoes. Periods with no observation are indicated with grey, negative bars.

Usage

plotLongitudinalMTR(
  mtr,
  maxMTR,
  timeRange = NULL,
  targetTimeZone = "Etc/GMT0",
  plotClass = "allClasses",
  propObsTimeCutoff = 0.2,
  plotSpread = TRUE,
  filePath = NULL
)

Arguments

mtr

data frame with MTR values created by the function ‘computeMTR’.

maxMTR

optional numeric variable, fixes the maximum value of the y-Scale of the plot to the given value. If negative or not set, the y-Scale is auto-scaled.

timeRange

optional list of string vectors length 2, start and end time of the time ranges that should be plotted. The date/time format is “yyyy-MM-dd hh:mm”.

targetTimeZone

"Etc/GMT0" String specifying the target time zone. Default is "Etc/GMT0".

plotClass

character string with the class of which the MTR data should be plotted. If not set or set to “allClasses”, MTR of all classes will be plotted.

propObsTimeCutoff

numeric between 0 and 1. If the MTR is computed per day and night, time bins with a proportional observation time smaller than propObsTimeCutoff are ignored when combining the time bins. If the MTR is computed for each time bin, the parameter is ignored.

plotSpread

logical, choose if the spread (first and third quartile) should be plotted.

filePath

character string, path of the directory where the plot should be saved. The function ‘savePlotToFile’ is used to save the plots as png files with an auto-generated filename.

Value

png files stored in the directory specified with 'filePath'
