#' boot_f_pcor
#'
#' Generate R bootstrap replicates of a statistic applied to data.
#'
#' @param data The data as a vector, matrix or data frame. If it is a matrix or data frame then each
#' row is considered as one multivariate observation.
#' @param indices indices to be used for calculation
#' @param cor.type a character string indicating which correlation
#' @param fun a function to use in bootstrap procedure
#' coefficient is to be computed. One of "pearson" (default), "kendall", or
#' "spearman".
#'
#' @return A matrix with bootstrapped estimates of partial correlation coefficients
