plot.MarkovTest: Plot method for a MarkovTest object

In mstate: Data Preparation, Estimation and Prediction in Multi-State Models

Plot method for a MarkovTest object

Description

Plot method for an object of class 'MarkovTest'. It plots the trace of the log-rank statistics provided by MarkovTest.

Usage

## S3 method for class 'MarkovTest'
plot(
  x,
  y,
  what = c("states", "overall"),
  idx = NULL,
  quantiles = TRUE,
  qsup,
  states,
  xlab,
  ylab,
  main,
  ...
)

Arguments

x	Object of class 'MarkovTest'
y	The grid at which MarkovTest was calculated
what	Choose "states" for plotting state-specific traces, and "overall" for the overall chi-squared trace
idx	Vector of indices of wild bootstrap traces to plot
quantiles	Boolean whether or not to plot the 2.5 and 97.5 percent quantiles, default is TRUE
qsup	The index of the function in either fn (when plotting state-specific) or fn2 (when plotting overall) to plot along with the traces; when missing this line is not included
states	Number of the qualifying state(s) to plot trace for
xlab	Text for x-axis label
ylab	Text for y-axis label
main	Text for title (main)
...	Further arguments to plot

Value

No return value

# Example provided by the prothrombin data
data("prothr")
# Apply Markov test to grid of monthly time points over the first 7.5 years
year <- 365.25
month <- year / 12
grid <- month * (1:90)
# Markov test for transition 1 (wild bootstrap based on 100 replications)
MT <- MarkovTest(prothr, id = "id", transition = 1,
                 grid = grid, B = 100)

plot(MT, grid, what="states", idx=1:50, states=rownames(attr(prothr, "trans")),
     xlab="Days since randomisation", ylab="Log-rank test statistic",

     xlab="Days since randomisation", ylab="Chi-square test statistic",
     main="Transition Normal -> Low")

plot(MT, grid, what="states", quantiles=FALSE) # only trace
plot(MT, grid, what="states") # trace plus quantiles (default)
plot(MT, grid, what="states", idx=1:10) # trace plus quantiles, plus first 10 bootstrap traces
