plot.hare  R Documentation 
Plots a density, distribution function, hazard
function or survival function for
a hare
object.
## S3 method for class 'hare'
plot(x, cov, n = 100, which = 0, what = "d", time, add = FALSE, xlim,
xlab, ylab, type, ...)
x 

cov 
a vector of length 
n 
the number of equally spaced points at which to plot the function. 
which 
for which coordinate should the plot be made. 0: time; positive value
i: covariate i. Note that if which is the positive value i, then the
element corresponding to this covariate must be given in 
what 
what should be plotted: 
time 
if which is not equal to 0, the value of time for which the plot should be made. 
add 
should the plot be added to an existing plot? 
xlim 
plotting limits; default is from the maximum of 0 and 10% before the 1st percentile to the minimmum of 10% further than the 99th percentile and the largest observation. 
xlab,ylab 
labels for the axes. Per default no labels are printed. 
type 
plotting type. The default is lines. 
... 
all other plotting options are passed on. 
This function produces a plot of a hare
fit at n
equally
spaced points roughly covering the support of the density. (Use
xlim=c(from,to)
to change the range of these points.)
