parseCoxph | R Documentation |

Creates a set of survival data and fits a `coxph`

model
using a survival formula and a data set.

```
parseCoxph(surv.formula, data, center = TRUE)
```

`surv.formula` |
A formula readable by 'coxph'. |

`data` |
a set of data containing covariate information for variables named by â€˜surv.formula'. Can be of any â€™completeness', as the function returns a reduced set. |

`center` |
Should the covariate matrices be mean-centered before being returned?
defaults to |

A list with class `parseCoxph`

containing:

`survdata`

reduced version of

`data`

, with only one row per subject, with covariates specified by`surv.formula`

along with survival time and failure status.`Smat`

matrix containing all requisite survival covariates (one row per subject).

`ph`

the model fit from

`coxph`

.`Delta`

list of failure indicators for each of the unique subjects.

`n`

number of unique subjects.

`ft`

vector of unique failure times.

`nev`

vector containing number of failures at each failure time

`ft`

.`survtime`

the name of the

`time`

variable in`surv.formula`

.`status`

the name of the

`event`

variable in`surv.formula`

.

```
data = simData()$data
parseCoxph(Surv(survtime, status) ~ bin, data = data)
```
