zdist_plot {cycleRtools} | R Documentation |
Display the time distribution of values within a dataset. The distribution
can also be partitioned into zones if the zbounds
argument is not
NULL
.
zdist_plot(data, column = "power.W", binwidth = 10, zbounds = NULL, character.only = FALSE, ...)

data(ridedata) ## Using power. zdist_plot( data = ridedata, column = power.W, binwidth = 10, # 10 watt bins. zbounds = c(100, 200, 300), xlim = c(110, 500), xlab = "Power (Watts)", main = "Power distribution" # Argument passed to barplot. ) ## Using speed. zdist_plot( data = ridedata, column = speed.kmh, binwidth = 2, # 2 km/hr bins. zbounds = c(10, 20, 30), xlab = "Speed (km/hr)", main = "Speed distribution" ) ## Without zone colouring (produces a warning). zdist_plot( data = ridedata, column = speed.kmh, binwidth = 5, # 2 km/hr bins. xlab = "Speed (km/hr)", main = "Dull" )
