Scatterplot color options in CAR package?
Hi All.
I'd like to change the default plotting colors used to construct a
scatterplot with regression line in the CAR package.
So,
scatterplot(y~pred,smooth=FALSE, xlab="X", ylab="Y", lwd=2)
If I change the palette (e.g., palette(ranbow(6)), I can change the color of
the lines and points.
However, the axes and labels remain in black (i.e., the first color in the

(CAR) Scatterplot and problems (?) with abline
Network Blitz
I'm trying to generate a graph to summarize Interest Rate Parity. This
involves a scatterplot of x against y where the x and y limits are set
so to center the graph on 0,0 and then adding each axis line and a 45
degree line. Using CAR's scatterplot (sample code below) everything
except the axes plot fine:

Hello all!
System: R2.0.1, W2k.

I want to control plotting symbols and colours to match plots from
other, less flexible, systems. I also need to make all text and

categorical variable in scatterplot (car)
Hello R folks,
I am encountering a problem with the following scatterplot function from the
car package:
> scatterplot(y~x|z)
where y and x are continuous (interval) random variables and z is a
categorical variable. When z is a categorical variable coded 1 or 2, I
(appropriately) get a scatterplot of y by x, coded by z. Similarly, when z
is a categorical variable coded 1, 2, or 3, there is

Removing default loess line from scatterplot ({car})
scatterplot() is autogenerating a regression and loess line. I want to remove
the loess line, but can only find samples for how to add it. I definitely do
not have code that adds it (see below), so I am puzzling...

nnet question
Hello,
I use nnet to do prediction for a continuous variable.
after that, I calculate correlation coefficient between predicted value and
real observation.
I run my code(see following) several time, but I get different correlation
coefficient each time.
Anyone know why?
In addition, How to calculate prediction accuracy for prediction of
continuous variable?

how to avoid to overwrite object
Dear R list,
I have a question in R, it could be very simple, but I don't know how to do it?
for example:
I assign 6 to x in beginning of of my R script code
> x<-6
......
After many line code, I forget using x variable before, I use x
again, and do assignment like this
> x<-45
> x
[1] 45
then value 6 of previous x is replaced by 45.
I am wondering if there are some way R

scatterplots in car package
Hi, using scatterplot in 'car' package.
There are 4 plots to be pictured together (ignore data used):
library(car)
par(mfrow=c(3,1))
ts.plot(rnorm(100))
ts.plot(rnorm(100))
scatterplot(rnorm(100),rnorm(100),boxplot="",smooth=T) # scatter with
non-parametric fit
problem is that the last one comes 'always' separate.
Is there any way to solve it?? of course can use
