Spectrum plots

Description

High-level functions that plot the sum numerical abundance (N) or biomass abundance (B) in equally-spaced log10 body-mass bins.

Usage

PlotBSpectrum(community, 
              lower = min(NP(community, "M"), na.rm = TRUE), 
              upper = max(NP(community, "M"), na.rm = TRUE), 
              n.bins = 10, 
              main = CPS(community)$title, 
              xlab = Log10MLabel(community), 
              ylab = Log10BLabel(community), 
              xlim = NULL, 
              ylim = NULL, 
              pch = 19, 
              show.bin.limits = TRUE, 
              show.bin.centres = FALSE, 
              ...)

PlotNSpectrum(community, 
              lower = min(NP(community, "M"), na.rm = TRUE), 
              upper = max(NP(community, "M"), na.rm = TRUE), 
              n.bins = 10, 
              main = CPS(community)$title, 
              xlab = Log10MLabel(community), 
              ylab = Log10NLabel(community), 
              xlim = NULL, 
              ylim = NULL, 
              pch = 19, 
              show.bin.limits = TRUE, 
              show.bin.centres = FALSE, 
              ...)
