Please make lowess() generic (was: Reorganization of packages in the R distribution)
As I've mentioned a number of times. I find it very useful to have lowess()
become a generic function so that a lowess.formula() can be defined.
Below is a patch that makes both changes, as well as updating the
corresponding help documentation.

R-2.0.0 Install problem for package bundle with inter-dependent n amespaces
I have a revised version of the gregmisc package, which I've converted into
a package bundle each of which has a namespace: gplots, gmodels, gdata,
gtoools. Of course, there are interdependencies among these namespaces:

S4 generic for lowess
Hi,
A lowess method is defined in our package for one of our S4 classes. To
explicitely define the generic this is being used
if (!isGeneric("lowess"))
setGeneric("lowess", useAsDefault = lowess)
This works fine for many other methods inherited from various R
packages. In this case a warning is issued in R CMD check:

A Question on lowess() function
Hi, all,
I want to use lowess(x, y) where x and y are vectors of length of 4000+. In
fact, x and y are log of some vectors. So, some of the elements are NaN.
lowess() can not take away those elements then do the fitting. It will give
the error message and do nothing.
1. Can anybody tell me how to get rid of those NaN's and use lowess()?
2. How to get the LOWESS fitting values for any

permutations of n choose r. It also contains 'combinations' which generates
all combinations, and which appears to match your example:

add lowess predicted line to scatter plot
Hi,
I have a scatter plot of the variables GNI and Lifeexp (Gross National
Income and Life Expectancy, both metric). So I plotted them and I want to
add a regression line and a lowess line. I use lowess and not loess because
I have missing values. My code:
plot(GNI,Lifeexp)
abline(lm(Lifeexp~GNI), col="red")
y.loess<-loess(Lifeexp~GNI,na.
action = na.exclude)

Please make lowess() generic (was: Reorganization of pac kagesin the R distribution)
I don't really see the point. lowess() is a two-dimensional smoother only
so the main point would only be to allow lowess(y ~ x, dat) instead of
lowess(dat$x, dat$y).

95% CI bands on a Lowess smoother
Hi there,
I'm plotting some glass RI values just by plotting
plot(x)
then I put on my lowess smoother
lines(lowess(x))
now I want to put on some 95% Confidence Interval bands of the lowess
smoother, but don't know how??
Thanks

Proposal: 'global' package refactoring
Looking over the contents of various packages, including my own, it is clear
that lots of things end up 'hidden away' in packages where they don't
belong. My gregmisc package is a particularly egregious example, containing
something from almost every functional category.
I propose that from time to time the R community go through the complete set
of packages and 'refactor'

how to sample lowess/loess into matrix ?
code:
x <- rnorm(32)
y <- rnorm(32)
plot(x,y)
lines(lowess(x,y),col='red')
Now I need to sample the lowess function into matrix where one series will
be X and other will be values of lowess at particular X.

xyplot with lowess curves
I am trying to change the attributes of the lowess lines fit to an
xyplot command, but have been unsuccessful in my search of the online
help. Right now, both the points and lowess line come out in the same
color (blue). I am unsure how I can change the properties of the lowess
line separately.
