Formula wrapper for the muhaz function from the muhaz package.

Description

Formula wrapper for the muhaz function from the muhaz package.

Usage

muhaz2(formula, data, subset, max.time, ...)
## S3 method for class 'muhaz2'
plot(x, haz.scale=1, ylab="Hazard", ylim=NULL, log="", ...)
## S3 method for class 'muhazList'
plot(x, lty=1:5, col=1:length(x), log="", legend.args=list(), ...)
## S3 method for class 'muhaz2'
lines(x, ..., haz.scale = 1)
## S3 method for class 'muhazList'
lines(x, lty=1, col=1:length(x), ...)
## S3 method for class 'muhazList'
summary(object, ...)
## S3 method for class 'muhazList'
ggplot(data, mapping=NULL, 
                            xlab="Time", ylab="Hazard", ...,
                            environment = parent.frame())
## S3 method for class 'muhazList'
as.data.frame(x, row.names, optional, ...)
## S3 method for class 'muhaz'
as.data.frame(x, row.names, optional, ...)

Arguments

formula	formula with the left-hand side being a Surv object, including a time and event indicator, and the right-hand side indicated stratification.
data	optional data.frame for the Surv object. If this is not provided, then the parent frame is used for the Surv object.
subset	subset predictate for the dataset
max.time	maximum follow-up time for the hazards
xlab	graphics argument for xlab (x-axis label)
ylab	graphics argument for ylab (y-axis label)
lty	graphics argument for line type
col	graphics argument for line colour
legend.args	a list of options that are passed to the legend call. Defaults are list(x="topright",legend=names(x),col=col,lty=lty).
haz.scale	scale for the hazard in the plot
row.names	not currently used
object	muhazList object
ylim	graphics argument for the limits of the y axis
log	graphics argument for a log transformation of the x or y axes
x	muhazList or muhaz object
environment	*[Deprecated]* Used prior to tidy evaluation.
optional	not currently used
mapping	Default list of aesthetic mappings to use for plot. If not specified, must be supplied in each layer added to the plot.
...	other arguments

Value

For a single strata, this is a muhaz object. For multiple strata, this is a muhazList object, which includes methods for

Examples

  plot(muhaz2(Surv(surv_mm, status == "Dead: cancer")~1, melanoma))
