plot-method function

Plot Baseline Rate or Mean Cumulative Function (MCF)

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.

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

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

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

## S4 method for signature '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.

Returns

A ggplot object.
