multiPlotSP: Plots several single-phase transport profiles overlayed
In transmem: Treatment of Membrane-Transport Data

Description Usage Arguments Details Value Author(s) Examples

Given a list of several complete transport data, the function overlays the transport profiles in a defined phase. The function is useful in membrane reuse experiments as transport profile deterioration is easily visualized.

multiPlotSP(trans, phase = "strip", trend = NULL, legend = FALSE,
  xlab = "Time (h)", ylab = expression(Phi), xlim = NULL, ylim = NULL,
  xbreaks = NULL, ybreaks = NULL, size = 3, plot = TRUE, shape = 15,
  bw = FALSE, arw = FALSE, arw.pos = NULL, arw.txt = NULL,
  txt.pos = NULL, txt.size = NULL)

`trans`	List of data frames with the complete transport information of interest species. Must be generated using `conc2frac`. This is the only non-optional parameter.
`phase`	Phase to be represented in the plot: `'strip'`, the default, or `'feed'`.
`trend`	List of Non-linear regression models of the main species transport profil. Generated using `transTrend`.
`legend`	Logical. If `FALSE`, the default, the legend is not included.
`xlab`	Label to be used for x axis. Text and expression allowed.
`ylab`	Label to be used for y axis. Text and expression allowed.
`xlim`	Numeric vector of limits for X-axis.
`ylim`	Numeric vector of limits for X-axis.
`xbreaks`	Numeric vector of x-axis breaks.
`ybreaks`	Numeric vector of x-axis breaks.
`size`	Size used for points in the plot.
`plot`	Logical. If `TRUE`, the default, the plot is printed in the current graphical device.
`shape`	Shape to use in the points to be plotted.
`bw`	Logical, if `FALSE`, the default, a color version of the plot is given. If a black and white version is required, it must be set to `TRUE`.
`arw`	Logical default to `FALSE`. If `TRUE`, a vertical arrow is drawn in the plot. Its use is recommended when a trend along the profiles is to be indicated.
`arw.pos`	Numeric vector of the coordinates of the arrow if `arw = TRUE`. The format is (x0, x1, y0, y1)
`arw.txt`	Text to be (optionally) printed alongside the arrow.
`txt.pos`	Numeric vector of the position of the center of the text provided in `arw.txt`. The format is (x, y). If not provided, the text is located close to the arrow but a little alignment could be required.
`txt.size`	Size of the text accompanying the arrow.

Most transmem graphical representations are made using the package ggplot2 so the function returns a ggplot2 object that can be assigned to a variable for further modification.

  # First step is to get trend lines for each cycle:
  trend <- list()

  }
  # Default plot using colors:
  multiPlotSP(trans = reusecycles, trend = trend, legend = TRUE)

  # Black and white plot including an arrow:
  multiPlotSP(trans = reusecycles, trend = trend, legend = TRUE, bw = TRUE,
