plot = TRUE, the resulting object of class hist.lengths is plotted before it is returned."hist"(x, ..., log = FALSE, zeros.rm = TRUE)lengths, typically with the output of the function getlen.hist.TRUE, histograms will be calculated for the logarithm of the lengths. It is FALSE by default.FALSE, histograms will be computed by including zero values. It is TRUE by default.plot = TRUE, an image is produced on the current graphics device. The function returns an object of class hist.lengths. It contains class histogram objects, the given direction of the stratum lengths and a logical value which points out if histograms are computed for the logarithm of stratum lengths.getlen, hist, density.lengths, plot.density.lengths
