\title{ Find fragments }
\description{
  Function to identify which fragment(s) in a list of fragments match a given molecular weight
}
\usage{
findFragments(MW, fragments, resolution = 1)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{MW}{ Molecular weight target (in Da) }
  \item{fragments}{ List of molecular weights corresponding to unique fragments }
  \item{resolution}{ Resolution (in Da), used to specify the ability to distinguish two different molecular weights. For a resolution of \option{1} (default), two molecular weights are considered identical if they are less than \option{1} Da apart.}
}
\value{
  Returns the index or indices of fragment(s) within the input list that have a molecular weight which matches that specified as input
