Plot free energy surface object

`plot.fes` plots free energy surface. For a fes with one collective variable it plots a 1D profile. For a fes with two collective variables it plots 2D free energy surface using image, contours or combination of both (default).

# S3 method for fes
plot(x, plottype = "both", colscale = F, xlim = NULL,
  ylim = NULL, zlim = NULL, main = NULL, sub = NULL, xlab = NULL,
  ylab = NULL, nlevels = 10, levels = NULL,
  col = rainbow(135)[100:1], labels = NULL, labcex = 0.6,
  drawlabels = TRUE, colscalelab = "free energy",
  method = "flattest", contcol = par("fg"), lty = par("lty"),
  lwd = 1, asp = NULL, axes = T, ...)

Arguments

x

fes object.

plottype

specifies whether 2D free energy surface will be plotted as image, contours or both (default "both").

colscale

specifies whether color scale will be plotted (default False).

xlim

numeric vector of length 2, giving the x coordinates range.

ylim

numeric vector of length 2, giving the y coordinates range.

zlim

numeric vector of length 2, giving the z coordinates range.

main

an overall title for the plot: see 'title'.

sub

a sub title for the plot: see 'title'.

xlab

a title for the x axis: see 'title'.

ylab

a title for the y axis: see 'title'.

nlevels

number of contour levels desired if 'levels' is not supplied.

levels

numeric vector of levels at which to draw contour lines.

col

color of the free energy surface. For 1D surface it is the color of the line. For 2D it is a list of colors such as that generated by 'rainbow', 'heat.colors', 'topo.colors', 'terrain.colors' or similar functions (default=rainbow(135)[100:1]).

labels

a vector giving the labels for the contour lines. If 'NULL' then the levels are used as labels, otherwise this is coerced by 'as.character'.

labcex

'cex' for contour labeling. This is an absolute size, not a multiple of 'par("cex")'.

drawlabels

logical. Contours are labeled if 'TRUE'.

colscalelab

color scale label (default "free energy").

method

character string specifying where the labels will be located. Possible values are '"simple"', '"edge"' and '"flattest"' (the default). See the 'Details' section.

contcol

contour color.

lty

line type for the lines drawn.

lwd

contour line width.

asp

the y/x aspect ratio, see 'plot.window'.

axes

a logical value indicating whether both axes should be drawn on the plot.

...

further arguments passed to or from other methods.

Examples

tfes2d<-fes(acealanme, imax=5000)
plot(tfes2d)

tfes1d<-fes(acealanme1d)
plot(tfes1d)
