plot_sensorimage: sensor image

In KiranLDA/PAMLr: Suite Of Functions For Manipulating Pressure, Activity, Magnetism, Temperature And Light Data In R

sensor image

Description

This function plots sensor data as an image. An actogram for instance is a type of sensor image.

Usage

plot_sensorimage(
  date,
  sensor_data,
  tz = "UTC",
  plotx = TRUE,
  ploty = TRUE,
  labelx = TRUE,
  labely = TRUE,
  offset = 0,
  dt = NA,
  xlab = "Hour",
  ylab = "Date",
  cex = 2,
  na.col = "white",
  col = c("black", viridis::magma(90)),
  ...
)

Arguments

date	Date data in POSIXct format, most commonly PAM_data$acceleration$date
sensor_data	sensor data, for example look at PAM_data$acceleration$act
tz	Time zone for POSIXct, default set to "UTC"
plotx	wherether or not to plot the x axis ticks + labels (for instance when compiling multifigures)
ploty	wherether or not to plot the y axis ticks + labels (for instance when compiling multifigures)
labelx	wherether or not to write the name of the x axis (for instance when compiling multifigures)
labely	wherether or not to write the name of the y axis (for instance when compiling multifigures)
offset	This parameter determines where the center of the graph is. When offset = 0, then midday is at the center of the graph. when offset=12 midnight'
dt	the time interval to which the data are resampled (secs). Default is NA
xlab	label for x-axis (as a character string)
ylab	label for y axis (as a character string)
cex	size of labels
na.col	colour given to NA values, default is "white"
col	Colour scheme of plot. Default col = c("black",viridis::magma(90))
...	Any additional parameters used by graphics::image

Value

an image of the sensor data, for instance with activity it would produce an actogram
