smoothCoxph {phenoTest} | R Documentation

## Plots the Cox proportional hazard smoothed by gene expression level.

### Description

Builds a plot showing how hazard behaves over different levels of expression of a given gene. Confidence intervals are also provided.

### Usage

    smoothCoxph(time, event, x, xlim, ylim, xlab, ylab, logrisk=TRUE, ...)

### Arguments

`time` | variable where time to survival is stored.
`event` | variable where survival event is stored.
`x` | `numeric` containing the expression levels of a given gene.
`xlim` | `xlim` for the plot.
`ylim` | `ylim` for the plot.
`xlab` | `xlab` for the plot.
`ylab` | `ylab` for the plot.
`logrisk` | `logrisk` if we want to compute risk or logrisk estimates. By default this is TRUE, which has a better behaviour under small sample sizes.
`...` | other arguments that will be passed to plot.
