similar to: lowess() as a generic function

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. Gregory R.

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: gsun374: /tmp [11]> cd gregmisc/ gsun374: gregmisc [12]> grep import */NAMESPACE gdata/NAMESPACE:importFrom(gtools, odd, invalid, mixedsort)

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: * checking R code for possible problems ... NOTE

Version 0.8.0 of the gregmisc package is now (or will shortly be) available on CRAN.

Colleagues ---------------------------------- System info: R version rw1022 on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- I would like to access the residuals from a lowess fit (function lowess() ) as an aid to assessing whether I am over-smoothing or under-smoothing a dataset (as in Cleveland's book "Visualizing data", section 3.3) Unless I

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

The gregmisc package contains a function 'perumutations' which generates all permutations of n choose r. It also contains 'combinations' which generates all combinations, and which appears to match your example: > library(gregmisc) Loading required package: MASS Attaching package `gregmisc': The following object(s) are masked from package:base :

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)

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).

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'

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. -- View this message in context: http://r.789695.n4.nabble.com/how-to-sample-lowess-loess-into-matrix-tp3053458p3053458.html Sent from the R help mailing list archive at

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).
