calcComfInd calculates one or more thermal comfort indices using a list of climatic conditions.
calcComfInd(lsCond, request = "all")comfind(lsCond, request = "all")
calcComfInd returns one or more rows with the comfort indices listed as request. For details see details above.
a list of climatic conditions and additional variables necessary for one or more of the indices (see details below).
a vector with one or more comfort indices (see details below).

| wt | weight (kg) |
| ht | height (cm) |
| trm | Running mean outdoor temperature in (degree C) |
