draw.wd {wavethresh} | R Documentation |
Draws picture of the wavelet associated with (1D or 2D) wavelet decomposition
object wd
, as opposed to drawing wd
itself (which is
achieved by the corresponding plot
method, such as
plot.wd
).
## S3 method for class 'wd': draw(x, ...) draw.imwd (x, resolution = 128, ...) draw.imwdc(x, resolution = 128, ...)
x |
Object of class wd , imwd , or imwdc ,
typically from a wavelet decomposition using
the wd , imwd , or
threshold function. |
resolution |
integer specifying the resolution to use in drawing. A higher resolution gives a better quality picture but will take longer to draw (especially in two dimensions). |
... |
further arguments to draw.default . |
Sometimes it is more convenient to use this function rather than
draw.default
, since you want a picture of the wavelet
that did your decomposition.
example(wd) # Draw a picture of the wavelets that were used draw(wds); abline(h=0,v=0, lty=3, lwd=.5) example(imwd) # Draw a picture of the 2D wavelet that used draw(imwdL)
