plot.rs.zph {relsurv} | R Documentation |
Displays a graph of the scaled partial residuals, along with a smooth curve.
## S3 method for class 'rs.zph': plot(x, resid=TRUE, df = 4, nsmo = 40,var,cex=1,add=FALSE,col=1, lty=1,xlab,ylab,scale=1,...)
x |
result of the rs.zph function.
|
resid |
a logical value, if TRUE the residuals are included on the
plot, as well as the smooth fit. |
df |
the degrees of freedom for the fitted natural spline, df=2
leads to a linear fit.
|
nsmo |
number of points used to plot the fitted spline. |
var |
the set of variables for which plots are desired. By default, plots are produced in turn for each variable of a model. Selection of a single variable allows other features to be added to the plot, e.g., a horizontal line at zero or a main title. |
cex |
a numerical value giving the amount by which plotting text and symbols should be scaled relative to the default. |
add |
logical, if TRUE the plot is added to an existing plot |
col |
a specification for the default plotting color. |
lty |
the line type. |
xlab |
x axis label. |
ylab |
y axis label. |
scale |
units for x axis, default is 1, i.e. days. |
... |
Additional arguments passed to the plot function. |
