Sorry, I must be looking at a different section but when I look at 3.4 in
r-intro.pdf I see:
3.4 The class of an object
All objects in R have a class, reported by the function class. For simple
vectors this is just the
mode, for example "numeric", "logical", "character" or "list", but "matrix",

So the title should be "How does the specific incarnation of object orientation
in R work?" Try, for example, section 3.4 and
My question is how does 'plot' know to implicilty call the plot.ts (in the case
of the full "exact" spectrum being fed back into the inverse?

Generate the square wave:
genseq <- function()
{
x <- numeric(4*365)
s <- seq(as.Date("2005-01-01"), as.Date("2008-12-31"), by="month")
ob <- as.vector(s[c(10,22,34,46)] - as.Date("2005-01-01"))
oe <- as.vector(s[c(11,23,35,47)] - as.Date("2005-01-01"))
for(.index in 1:length(ob))

Mmm... don't fully understand what you mean, mainly because your program example
did not run and I had do s
So iis what you are saying n plotting the list of compliex numbers 'R'
recognizes the non-symmery and plots it differently (Re vs. Im) rather than

Your example is not self-running, because the definition of e is unclear.

I have a a simple function that generates a time series square wave:
genseq <- function()
{
x <- numeric(4*365)
s <- seq(as.Date("2005-01-01"), as.Date("2008-12-31"), by="month")
ob <- as.vector(s[c(10,22,34,46)] - as.Date("2005-01-01"))
oe <- as.vector(s[c(11,23,35,47)] - as.Date("2005-01
