graph_TRH: Graph temperature and humidity data

In ConSciR: Tools for Conservation Science

Graph temperature and humidity data

Description

Use this tool to produce a simple temperature and humidity plot with optional background bands showing target temperature and relative humidity ranges. Optionally, add a function to graph, e.g. 'calcDP', 'calcAH', etc.

Usage

graph_TRH(
  mydata,
  Date = "Date",
  Temp = "Temp",
  RH = "RH",
  facet_by = "Sensor",
  LowT = 16,
  HighT = 25,
  LowRH = 40,
  HighRH = 60,
  y_func = "none",
  ...
)

Arguments

mydata	A data frame containing date (Date), temperature (Temp), and relative humidity (RH) columns.
Date	The name of the column in mydata containing date information ("Date").
Temp	The name of the column in mydata containing temperature data ("Temp").
RH	The name of the column in mydata containing relative humidity data ("RH").
facet_by	Name of categorical column to facet by; defaults to "Sensor".
LowT	Numeric lower bound of temperature range (default 16).
HighT	Numeric upper bound of temperature range (default 25).
LowRH	Numeric lower bound of relative humidity range (default 40).
HighRH	Numeric upper bound of relative humidity range (default 60).
y_func	Character string specifying a function to apply to temperature and humidity columns (e.g. "calcAH"). Default is "none".
...	Additional arguments passed to y_func.

Value

A ggplot graph of temperature and relative humidity with optional background bands.

Examples

# mydata file
filepath <- data_file_path("mydata.xlsx")
mydata <- readxl::read_excel(filepath, sheet = "mydata", n_max = 1000)

# Basic use with background ranges
graph_TRH(mydata)

# Add dew point and customise
graph_TRH(mydata, y_func = "calcDP", LowT = 6, HighT = 28)
