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.

Error in ?lowess
The lowess() help page refers to documentation in "src/appl/lowess.doc".
This was moved to "src/library/stats/src/lowess.doc" in 2007. This

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.

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:

scaling of different data sets in ggplot
Dear list (but probably mostly Hadley):
In ggplot, operations to modify 'guides' are accessed through grid
objects, but I did not find mention of creating new guides or possibly
removing them altogether using ggplot functions. I wonder if this is
something I need to learn grid to learn more about (which I hope to do
eventually).
Also, ggplot()+geom_object() [where 'object' can be

anomalies with the loess() function
Hello Masters,
I run the loess() function to obtain local weighted regressions, given
lowess() can't handle NAs, but I don't
improve significantly my situation......, actually loess() performance leave

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

Problem with figure size when embedding fonts

I need to make a graphic that uses the Nimbus rather than Helvetica font
family so that the font can be embedded in the encapsulated postscript
file. This is to satisfy a requirement from a journal for electronic
submission of figures. I do the following:

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

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.

lowess() as a generic function
Hi All,
I've been providing a generic version of lowess() in my 'gregmisc' library,
along with a 'lowess.formula' and 'lowess.default'.
Can/should these be moved into base?

use the source code in my own c code
Hi there,
I am trying to use the source code for lowess (lowess.c in the src\appl
directory of R sources).
The problem is that some other files are included in lowess.c that I
don't know where to find them!
Any idea what I need to do to get able to use the source code?
Thanks in advance,

nonparametric logistic regression based on locally weighted scatterplot smoothing (lowess)

Recently, I have read an article regarding the association between age and

In statistical analysis, the authors stated "Because a nonlinear
relationship between age and lymph node involvement was expected based on

multiple lowess line in one plot
I'm using this code to plot a smoothed line. These two columns of data
really represent 4 groups and I'd like to plot a separate line for each
group but have them all in the same plot. The R-Docs for lowess do not
seem to indicate some type of "GROUPS=var_name" option. What would be
the syntax for this?

lowess output looks wrong (PR#7891)
Just noticed nobody has commented on this, so I took a look, and I can't
see the problem (2.1.0 looks the same as 2.1.1 to me). What is supposed
to be wrong?
