digestMod {adductomicsR} | R Documentation

## modified `Digest` function (from OrgMassSpecR package)

### Description

allows maxCharge to be set to calculate precursor m/z

### Usage

    digestMod(sequence, enzyme = "trypsin", missed = 0,
    maxCharge = 8,IAA = TRUE, N15 = FALSE, custom = list())

### Arguments

`sequence` | a character string representing the amino acid sequence.
`enzyme` | is the enzyme to perform in silico digestion with
`missed` | the maximum number of missed cleavages. Must be an integer of 0 (default) or greater. An error will result if the specified number of missed cleavages is greater than the maximum possible number of missed cleavages.
`maxCharge` | numeric max charge charge for predicted precursor m/z
`IAA` | logical. TRUE specifies iodoacetylated cysteine and FALSE specifies unmodified cysteine. Used only in determining the elemental formula, not the three letter codes.
`N15` | logical indicating if the nitrogen-15 isotope should be used in place of the default nitrogen-14 isotope. calculation
`custom` | list of custom masses

### Details

see `Digest` for details of further function arguments.

### Value

dataframe

### Examples

    digestMod('MKWVTFISLLFLFSSAYSRGVFRRDAHKSEVAHRFKDLGEENFKALVLIA',
    enzyme = "trypsin", missed = 0, maxCharge = 8,IAA = TRUE, N15 = FALSE,
    custom = list())
