plot.rmsip: Plot RMSIP Results

Description

Produces a heat plot of RMSIP (Root mean square inner product) for the visualization of modes similarity.

Usage

# S3 method for rmsip
plot(x, xlab = NULL, ylab = NULL, col = gray(50:0/50),
      zlim=c(0,1), ...)

Value

Called for its effect.

Arguments

x

an object of class rmsip.

xlab

a label for the x axis, defaults to ‘a’.

ylab

a label for the y axis, defaults to ‘b’.

col

a vector of colors for the RMSIP map (or overlap values).

zlim

the minimum and maximum ‘z’ values for which colors should be plotted.

...

additional arguments to function image.

Examples

## Read PDB structure
pdb <- read.pdb( system.file("examples/1hel.pdb", package="bio3d") )

## Perform NMA
modes.a <- nma(pdb, ff="calpha")
modes.b <- nma(pdb, ff="anm")

## Calculate and plot RMSIP
r <- rmsip(modes.a, modes.b)
plot(r)
