Description Usage Arguments Value See Also Examples

Calculate maximal mean values for specified time periods.

`data` |
a |

`column` |
column in |

`windows` |
window size(s) for which to generate best averages, given in seconds. |

`deltat` |
the sampling frequency of |

`character.only` |
are column name arguments given as character strings? A backdoor around non-standard evaluation. Mainly for internal use. |

a matrix object with two rows: 1) best mean values and 2) the time at which those values were recorded

data(ridedata)
## Best power for 5 and 20 minutes.
tsec <- c(5, 20) * 60
mmv(ridedata, power.W, tsec)
## Generate a simple critical power estimate.
tsec <- 2:20 * 60
pwrs <- mmv(ridedata, power.W, tsec)
m <- lm(pwrs[1, ] ~ {1 / tsec}) # Simple inverse model.
coef(m)[1] # Intercept = critical power.
## More complex models...
m <- Pt_model(pwrs[1, ], tsec)
print(m)
## Extract the asymptote of the exponential model.
