display.dV_dx {espadon}R Documentation

Display of the volume density of a histogram

Description

The display.dV_dx function displays the volume density of a "histo" class object. Y-units are \(cm^3.Gy^{-1}\).

Usage

display.dV_dx(
  histo,
  add = FALSE,
  xgrid = TRUE,
  ygrid = TRUE,
  MC.plot = FALSE,
  MC.col = grey.colors(4, rev = TRUE),
  ...
)

Arguments

histo

"histo" class object. See espadon.class for class definitions.

add

Boolean indicating whether to display the background image.

xgrid

Boolean indicating the display of the x grid.

ygrid

Boolean indicating the display of the y grid.

MC.plot

Boolean. If MC.plot = TRUE, then display.dV_dx displays, if they exist, the quantile zones (Prob = 0, .025, .25, .5, .75, .975, 1) of variations in volume density.

MC.col

Character string, a valid palette with 4 colours corresponding to 100%, 95%, 50% and median of MC data.

...

Arguments xlab, ylab, xlim, ylim, main, type, col, lwd, lty and log managed by the plot function.

Value

Returns a plot of the differential histogram included in histo, with its median, and the quantile areas (0%-100%), (2.5%-97.5%) and (25%-75%) of the histo$dv_dx variations, if they exist.

Examples

# loading of toy-patient objects (decrease dxyz and increase beam.nb for 
# better result)
step <- 5
patient <- toy.load.patient (modality = c("rtdose", "rtstruct"),
                             roi.name = "gizzard", dxyz = rep (step, 3), 
                             beam.nb = 3)

# Calculation of the differential histogram
H <- histo.from.roi (patient$rtdose[[1]], patient$rtstruct[[1]], 
                     roi.name = "gizzard", breaks = seq (0, 60, by = 2))
display.dV_dx (H, lwd = 2, col = '#00ff00', ylim = c (0,10))
