Hi, cbind the dependent variables such as in:
x=rnorm(100)
e1=rnorm(100)
e2=rnorm(100)
e3=rnorm(100)
y1=2*x+e1
y2=-1*x+e2
y3=0.7*x+e3

Hello all,
I hope this question is appropriate for this ML.

variable holds some information about how it was created.

Hi Ken,
Perhaps something like
plot(x,y)
lines(sort(x), fit$fitted.values[order(x)])
should do what I think you want. I think you have to be a bit careful
on the ordering of the fitted values so that they match up with the
order of the x variable, otherwise you get an odd looking line plot.

Hi all,
I'm searching for a way to exclude outliers from my dataset while making
xyplots. While plotting using pairs(), I exclude specific row in my data frame
and save the settings as a variable which I later include as an argument:
# Discard outliers and save settings as idx
idx=with(fieldTr
Within the plot.lars code, change the type argument to matplot from 'b' to 'l':
library(lars)
myplot.lars <- edit(plot.lars)
#change type = 'b' to type = 'l' in the call to matplot
data(diabetes)
object <- with(diabetes, lars(x,y))
myplot.lars(object, lty = 1, breaks = FALSE)
hth,

When I do that, R hangs and don't show any message.

Dear R users,
I am a newbie. Just switched from MATLAB. So thanks a lot for your
patience.
I have 5 spectra collected in field. Each spectra has two columns :
Wavelength (56) and the actual measurement.
Each measurement came in a different .txt file on disk (5 files in
total). I wrote

As far as I know the RPostgreSQL package doesn't work in R 2.8

Hi all,
I was looking for a non parametric survival analysis and I came up with the
following sample from the web.
However, I could not run it. Which library or function does
"sm.regression" require?
x <- runif(100,-2, 2)
y <- x^2 + rnorm(50)
sm.regression(x, y, h=0.5)
Error: could not find fu
Thank you very much for your interest.
I make this:
x <- as.character(alumnos$AL_NUME_ID)
x <- x[-seq_len(length(x)/2)]
save(x, file="x.RData")
I exit form R, and then restart R and I make this:
load("x.RData")
y <- gsub("(^ +)|( +$)","",x)
It shows me:
Error en gsub("(^ +)|( +$)", "", x) :

When plotting a lars object, I cannot find a way to plot solid lines.
Even when the arguments breaks=F and lty="solid" are used, the vertical
lines at the break points do not plot but asterisks indicating the
breaks still plot as part of each path leaving solid lines broken up by
asterisks at the b

There are anova {stats} and aov in R. It seems that anova takes an

Dear All,
Apologies if my questions are too basic for this list.
I am given a set of data corresponding to list of detection times (real,
non-integer numbers in general) for some events, let us say nuclear
decays to fix the ideas.
It is a small dataset, corresponding to about 400 nuclear decay
Hi Baptisti,
Sorry for the late reply. I wanted to thank you for putting me on the
right track. I finally got something to work not really by extracting
the legend from a xyplot call, but by building my own legend grid.frame
and passing it to my low-level function. Understanding Grobs and
