plot.tfCox {tfCox}

Plot Fitted Functions from Class "tfCox"

Description

This function plots the fitted functions from a model estimated by tfCox.

Usage

## S3 method for class 'tfCox'
plot(x, which.lambda=1, which.predictor = NULL, n.plot = 4, ...)

Arguments

x

an object of class "tfCox"

which.lambda

the index for the model of interest to be plotted. which.lambda corresponds to the model fit in lambda.seq and should be integer between 1 to length(fit$lambda.seq). In other words, the fit from fit$theta.list[[which.lambda]] will be plotted.

which.predictor

a vector of predictor index that indicates which predictor function to plot. The vector should have integer values from 1 to p where p is the number of predictors.

n.plot

the number of predictors to be plotted (default is 4). Note that only those non-zero estimated functions will be plotted. If which.predictor is supplied, this argument is ignored.

...

additional arguments to be passed. These are ignored in this function.
