Defines functions callMetrics

Documented in callMetrics

#' Calculate the metrics of insert size
#'
#' @importFrom magrittr %>%
#' @import dplyr
#' @param path The root folder containing all groups folders,
#'     default is the present working folder.
#' @param groups The name of the groups, the input value should be vector,
#'     e.g. groups=c('group1','group2'),
#'     default is all sub-folders in the 'path'.
#' @param fun String value, the types of metrics to be calculated.
#'    Default is 'all', which means both median and mean values
#'    will be returned.
#' @param outfmt The output format, a 'list' or 'dataframe' or 'df',
#'     default is dataframe.
#' @param input_type Character. The input file format,
#'    should be one of these: 'picard', 'bam' or 'cfdnapro'. 
#'    The bam files has to be marked duplicates.
#' @param ... Further arguments passed to or from other methods.
#' @return  The inter valley distance in list or dataframe format.
#' @examples
#' # Get the path to example data.
#' path <- examplePath("groups_picard")
#' # Calculate the metrics.
#' df <- callMetrics(path = path)
