Arguments

x: object of class mrs_data.
xlim: the range of values to display on the x-axis, eg xlim = c(4,1).
mode: representation of the complex numbers to be plotted, can be one of: "re", "im", "mod" or "arg".
col: Colour map to use, defaults to viridis.
plot_dim: the dimension to display on the y-axis, can be one of: "dyn", "time_sec", x", "y", "z", "coil" or NULL. If NULL (the default) all spectra are collapsed into the dynamic dimension and displayed.
x_pos: the x index to plot.
y_pos: the y index to plot.
z_pos: the z index to plot.
dyn: the dynamic index to plot.
coil: the coil element number to plot.
restore_def_par: restore default plotting par values after the plot has been made.
y_ticks: a vector of indices specifying where to place additional red tick marks.
hline: add a horizontal line at the specified value.
hline_lty: linetype for the horizontal line.
hline_col: colour for the horizontal line.
vline: add a vertical line at the specified value.
vline_lty: linetype for the vertical line.
vline_col: colour for the vertical line.
legend: add a colour bar to the plot using the imagePlot function from the fields package.
...: other arguments to pass to the plot method.
