The functions `calcTroin`

calculates radiative and operative temperature based on air temperature, globe temperature, air velocity and metabolic rate. Globe temperature needs to be measured using a standard globe with a diameter of 0.15m and an emissivity of .95 (black coloured).

1 | ```
calcTroin(vel, tg, ta, met)
``` |

`vel` |
numeric value or vector presenting the air velocity in [m/s] |

`tg` |
numeric value or vector presenting the globe temperature in [degree C] |

`ta` |
numeric value or vector presenting the air temperature in [degree C] |

`met` |
numeric value or vector presenting the metabolic rate in [met] |

Calculation of the radiative temperature is based on ISO 7726:2001, equation (9). Calculation of operative temperature is based on ISO 7726:2001, Appendix G.3. The adjustment of air velocity to present relative air velocity based on metabolic rate is based on ISO 7730:2005 Appendix C.2.

`calcTroin`

returns a data.frame with radiative and operative temperature.

## Note. Due to random generated asv values. The values for the coefficients will not be meaningful.
## Create sample data
ta <- 20:24 # vector with air temperature values
vel <- rep(.1,5) # vector with air velocities
met <- rep(1.1,5) # vector with metabolic rates
tg <- 25:29 # vector with globe temperature values
calcTroin(vel, tg, ta, met)
