Arguments
MS1 |
data frame containing m/z, RT and intensity of ions from the first function |
db |
database to be searched for matches |
massdif |
mass difference between neutral mass and the adduct expected |
rt |
rt window |
n |
numeric value indicating whether to look for monomers (1), dimers (2), etc. |
charge |
numeric value indicating the expected charge of the ions |
Value
Subset of the original data frame without adducts
