Plot Baseline Rate or Mean Cumulative Function (MCF)

Source: R/plot.R
plot-method.Rd

S4 class methods plotting sample MCF from data, estimated MCF, or estimated baseline hazard rate function from a fitted model by using ggplot2 plotting system. The plots generated are thus able to be further customized properly.

Usage

# S4 method for mcf.formula,missing
plot(
  x,
  y,
  lty,
  col,
  legendName,
  legendLevels,
  conf.int = FALSE,
  mark.time = FALSE,
  addOrigin = FALSE,
  ...
)

# S4 method for mcf.rateReg,missing
plot(x, y, conf.int = FALSE, lty, col, ...)

# S4 method for baseRate.rateReg,missing
plot(x, y, conf.int = FALSE, lty, col, ...)

# S4 method for mcfDiff,missing
plot(
  x,
  y,
  lty,
  col,
  legendName,
  legendLevels,
  conf.int = TRUE,
  addOrigin = FALSE,
  ...
)

Arguments

x

An object used to dispatch a method.

y

An argument that should be missing and ignored now. Its existence is just for satisfying the definition of generaic function plot in package graphics for methods' dispatching.

lty

An optional numeric vector indicating line types specified to different groups: 0 = blank, 1 = solid, 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash, 6 = twodash.

col

An optional character vector indicating line colors specified to different groups.

legendName

An optional length-one charactor vector to specify the name for grouping each unique row in newdata, such as "gender" for "male" and "female". The default value is generated from the object.

legendLevels

An optional charactor vector to specify the levels for each unique row in newdata, such as "treatment" and "control". The default values are generated from the object.

conf.int

A logical value indicating whether to plot confidence interval. The default value is FALSE.

mark.time

A logical value with default value FALSE. If TRUE, each censoring time is marked by "+" on the MCF curves. Otherwise, the censoring time would not be marked.

addOrigin

A logical value indicating whether the MCF curves start from origin time. The default value is FALSE.

...

Other arguments for further usage.

Value

A ggplot object.
