\title{ Count peak collisions }
\description{
   Function to count the number of peak collisions (i.e. molecular weights are indistinguishable given the specified resolution)
}
\usage{
numCollisions(peaks, resolution = 0.5)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{peaks}{ Numerical list of molecular weights (in Da) corresponding to a set of peaks }
  \item{resolution}{ Resolution (in Da), used to specify the ability to distinguish two different molecular weights. For a resolution of \option{0.5} (default), two molecular weights are considered identical if they are less than \option{0.5} Da apart.}
}
\value{
  Returns a list of peak collision counts for each peak in the original list.
