Hello Dhiren,

Are there any libraries that will do a subset selection for glm's? I looked
through leaps, but seems like it is specifically for linear regressions.
?subset should tell you. AFAIK, subset function is not depend on a

Hi Tom,
You need to use the is.na test rather then the test x==NA because the
latter is not defined.
d-c(0,2,3,2,0,3,4,0,0,0,0,0)
d.mat-matrix(data=d,nrow=4,ncol=3,byrow=TRUE)
d.mat[d.mat==0]-NA
for(i in 1:length(d.mat[1,])){
d.mat[,i][is.na(d.mat[,i])] - mean(d.mat[,i],na.rm=TRUE)
}

Hi, all
I am trying to write a R package. I was able to build and install the

Hi,
I would like to regress y (dependent variable) on x (independent variable) and

I have create the y(-1) variable in this way: ly-lag(y, -1)
Now if I do the following regression lm (y ~ x + ly) the results I obtain are
not correct.
Can someone tell me the code to use in R in order to
My package structure is very simple.

Create time series from your data and then use lm with
the dyn or dynlm package (as lm does not support time
series directly). With the dyn package you just preface
lm with dyn$ and then use lm as usual:
library(dyn)
yt - ts(y)
xt - ts(x)
dyn$lm(yt ~ xt + lag(yt, -1))
After loading dyn try this

does anyone know how to visualize a response curve based on a regression model
with lines rather than dots. Having a large number of parameters the following

the process.

There may be an easier way, but here is one possible approach:
First, use scan to read in the data. Set the 'what' argument to a list
of atomic data types, based upon your specs above. Also, set the
'na.names' argument to '.'.

When looking at the previous postings regarding TRAMO-SEATS,

Is it true that we CANNOT replicate TRAMO-SEATS because of

If not, would anyone be interested in an R version of it, please?
