This function plots a DStree object on the current graphic
device. It visualizes the fitted tree as well as the
estimated survival/hazard probabilites for every terminal
node.
Usage
## S3 method for class 'DStree'
plot(x, prob = "surv", select = NULL, ...)
Arguments
x
a fitted object of class "DStree"
prob
a string that indicates which probability should be
plotted. "surv" draws survival probabilities,
"haz" draws hazard probabilities.
select
a vector of strings that indicate terminal leaves
for which the survival/hazard probabilities should be
drawn. If not specified probabilities for every terminal leaf
are drawn.
...
extra prp arguments to modify the
appearance of the tree (from R package
rpart.plot)
Examples
data(cost)
# Discretize observed days to years
d.cost<-dis.cost(cost)
# Grow tree
fit <- DStree(time~prevStroke+age+sex+alcohol+smoke,status="status",data=d.cost)
#Plot tree and survival probabilities
plot(fit)
#survival probabilities are in the first plot
#Plot tree and hazard probabilities for terminal leaves 4 and 15
plot(fit,prob="haz",select=c("2","7"))
