ri2rt {TargetSearch} | R Documentation |
Convert retention time indices to retention times indices based on observed FAME RI and their standard values.
ri2rt(riTime, rt.observed, ri.standard)
riTime |
And RI vector or matrix to convert to Retention Time. |
rt.observed |
The observed FAME RT's. It could be a vector or a matrix. |
ri.standard |
The standard RI for each FAME |
This function is the inverse of rt2ri
.
The converted RT
