)
data |
dataset with gas concentration measurements over time |
group |
name of the column that is used for grouping measurements ACHTUNG group sollte eine "_" enthalten da in der Funktion str_split(,"_") |
gas |
name of the gas |
Vol |
chamber Volum in ml (cm3) |
Grundfl |
area in m2 |

sollen die Werte nach group aggregiert werden |
P_kPA |
pressure in kPa |
data.frame with flux in different units for each group
