Unfortunately, the numbers [eg:CO2, Ch4, C5C8] in the leftmost column
create an issue that readAscciTable is not designed to handle.
CO2 1686 1489 1647 1643 1703 1585
CO 63 127 88 93 210 102
CH4 1.94 5.96 3.36 5.07 20.8 5.82
...
C5H8 0.039 0.15 0.099 0.13 1.38 0.38
readAsciiTable wants to treat these embedded numbers as data values.
Hence, you must explicitly extract the values.
Please read the documentation of the functions used.
