ARMAX Models in R
Hi,
I want to model different timeseries with ARMAX models in R because I think
that ARMAX models will map best to these data.
Besides I don't want to use the order of the AR or MA part but the lag e.g.
AR Part =ar1, ar2, ar7; MA Part =ma1, ma3 and I want to use exogenous
variables as well.
I coudn't find any solutions in the R help and therefore I want to ask all
of you.
Does anyone

Problem with plotting diagnostics - Error in object$coefficients : $ operator is invalid for atomic vectors
hi all,
after fitting a multiple linear regression
model <- lm(y ~ a + b+ c+d)
i wanted to plot diagnostics
plot(model)
but get the error message
Error in object$coefficients : $ operator is invalid for atomic vectors.
which does not make a lot of sense, since there is no "$" - i am working with an attached dataset.
can anyone help, please??
thanks a lot,

R debugging options
Hello,
What options are available for me to debug my R scripts? For example I
normally do something like
>source("myfunctions.R")
>function1("height", "weight")
myfunctions.R is a large R source file that contains many functions. function1
is the "main" function in myfunctions.R. It calls many other user-written
functions that are also in

Remove objects names like character String
Hi,
how can I use rm() on objects named like:
paste("site",i,"_data",sep="") while looping
through i?
I tried rm(paste("site",i,"_data",sep="")) but I get the error that
rm() must contain names or
text strings which is confusing me as I thought paste() would create
something like that...?
Thanks,

In the past I have used several different working directories for different
projects, and during many of these projects I have written some functions
for particular purposes. Now I thought I would be nice to have all these
"personal" functions collected in one place, and to make them available in R

How to create something between a script and a package
(Before starting: I'm a total R noob so please bear with me in case of
any error or faux pas).
Hi,
For a small project, I'm writing a few simple R functions and calling
them from python (using RPy). I'm sharing the code with a couple of
friends, using a subversion server.
Now, I want something like a package, to be able to share functions
between ourselves. Having read a few package

CCF for hourly time series?
Hello,
I have a dataframe containing various time series (not time series objects though!)with hourly time steps. I?d like to perform ccf for I need to know the correlation factors for different lags.
Here is an example:

I would like to produce a map with information about the patenting

degrees of patenting activity in different colors. I work with the
packages maptools, maps and spdep. The map data is read from an external

lattice: axis ticks, axis alignment and remove axis from plot
Hi there,
I'm a bit confused concerning the axis tck setting in the lattice
package as the ticks on left sided axis aren't
drawn at all with the following setting:
dados <- data.frame(varsep = factor(rep(1:2,10)),
i = runif(20))
library(lattice)
my.theme <- list(

distinguish regression lines in grouped, black and white lattice xyplot
Hi,
I've got the following problem which I cannot think of a solution right now:
if got a lattice xyplot in black and white and a grouping variable
with many (more than 8
values) and I plot it as regression lines (type="r"), just like this
one (not reproducable but that's
I guess not the point here):

recode letters to numbers
Hello,
I have a dataframe assigning various scores on around 20 variables to a list of
countries. The scores are rated on a scale of (D, C, B, A) and there are also
some not rated ones (NR) and others are left blank (NA). I now wanted to
transfer the scores into numeric values (such as NR=0, D=25, C=50, B=27, A=100),
while also leaving the NA in the dataframe. Can I transform the whole

Hi,
there´s something that really bothers me about R and after hours and hours of internet research, I´m still stuck with the same problem: I installed R and it is in Spanish, as the system on my work. I would really like it in English and there seems to be no way to change that!?! I´m doing an abroad internship, so my Spanish is far from perfect and my tutorial is in English.

linear model: Test difference between coefficients and given values (t.test?)
Hi there,
I've got a question which is really trivial for sure but still I have
to ask as I'm not
making any progress solving it by myself (please be patient with an
undergraduate
student):
I've got a linear model (lm and lmer fitted with method="ML").
Now I want to compare the coefficients (slope, intercept, not the
random effects)
of both models with a given value (e.g.
