rmap | R Documentation |
Utility functions for use in 2D phase unwrapping.
rmap(phase, dx = NULL, dy = NULL, plot = FALSE, ...)
wrap(phase)
phase |
Matrix of wrapped phase values |
dx |
Matrix of x differences |
dy |
Matrix of y differences |
plot |
Boolean: plot residue positions? |
... |
additional arguments for |
dx
and dy
must have the same dimension as phase
.
In rmap
if plot == TRUE
nr |
the number of residues identified in the map |
otherwise
phase |
wrapped phase returned by |
residues |
Matrix the same size as |
These are primarily intended for internal use
but can be used interactively. Calling rmap(phase, plot=TRUE)
will plot the positions of residues and return nothing.
If (plot==FALSE)
in the call to rmap
a matrix
the same size as phase
is returned with residues identified
with values of +1 or -1.
