statmlx {mlxR}

Summary of data

Description

Compute statistical summaries (mean, quantile, variance, survival rate,...)

Usage

statmlx(r, FUN = "mean", probs = c(0.05, 0.5, 0.95), surv.time = NULL)

Arguments

r

a data frame

FUN

a string, or a vector of strings, with the name of the functions to apply to the result of the simulation

probs

a vector of quantiles between 0 and 1. Only used when "quantile" has been defined in FUN

surv.time

a scalar or a vector of times. Only used when "event" has been defined in type

Details

See http://simulx.webpopix.org/stamlx for more details.

Value

A data frame.
