group.
fun(object, ...)
fun
, from the Math group, inherits
from class
"ptable"
.
ptable
object, each coefficient of which will have been transformed by the
generic function. The attribute
pcosts
will be set to
NULL
.
This is a group method for the functions of the
Math
group (
sin()
,
log()
,
round()
, etc), which are essentially all functions that return a one-to-one
numerical transformation of their (numeric) argument.
xx <- make.signal("bumps") ww <- wp.table(xx) sqrt(abs(ww)) # square-root of a wp.table
