setChrmMethod(method=c("alk.var5","alk.mdn35",
"fame.var5","fame.mdn35"), rt, ri, name="ChromMethod #1")

Arguments

method

The chromatographic method type to be used, currently, only ALK-VAR5 (alk.var5) type is available. However, this method is compatible with both Alkalanes and FAMEs, but only for chromatographic methods using VAR5-type columns.

rt

The retention times (RT) of the reference standards.

ri

The retention indexes (RI) of the reference standards.

name

The name of the chromatographic method, for further information.
