In rogiersbart/RMT3DMS: Pre- and post-processing of MT3DMS & MT3D-USGS files

rmt_plot.cbud plots a MT3DMS mass budget

## S3 method for class 'cbud'
rmt_plot(
  cbud,
  btn,
  icomp = 1,
  what = "cumulative",
  fluxes = "all",
  net = FALSE,
  type = "area",
  final = FALSE
)

`cbud`	`RMT3DMS` cbud object as obtained by `rmt_read_bud`
`btn`	`RMT3DMS` btn object
`icomp`	integer selecting for which species to plot the budget; defaults to 1
`what`	character; what to plot, "cumulative", "total", "difference" or "discrepancy". Defaults to "cumulative".
`fluxes`	character; either "all" or a character vector with the flux components to plot. Only used when `what` is "cumulative"
`net`	logical; if TRUE, it sums the inflows and outflows of the flux component to plot the net fluxes. If FALSE, it will plot both the inflows and outflows. Only used when `what` is "cumulative" or "total".
`type`	character; plot type. Either "bar" or "area".
`final`	logical; should only the final mass budget be plotted? Defaults to FALSE
