R: Plot survival curve for grpsurv model

plot.grpsurv.func {grpreg} | R Documentation

## Plot survival curve for grpsurv model

### Description

Plot survival curve for a model that has been fit using `grpsurv` followed by a prediction of the survival function using `predict.grpsurv`

### Usage

    ## S3 method for class 'grpsurv.func'
    plot(x, alpha=1, ...)

### Arguments

`x` | A `'grpsurv.func'` object, which is returned by `predict.grpsurv` if `type='survival'` is specified. See examples.
`alpha` | Controls alpha-blending (i.e., transparency). Useful if many overlapping lines are present.
`...` | Other graphical parameters to pass to `plot`

### Examples

    data(Lung)
    X <- Lung$X
    y <- Lung$y
    group <- Lung$group
    fit <- grpsurv(X, y, group)

    # A single survival curve
    S <- predict(fit, X[1,], type='survival', lambda=.05)
    plot(S, xlim=c(0,200))

    # Lots of survival curves
    S <- predict(fit, X, type='survival', lambda=.05)
    plot(S, xlim=c(0,200), alpha=0.3)
