Greetings R-help community,
I am relatively new to R, which may be why I am having trouble
understanding this problem. I want to know the differences between
vector and array. could someone tell me something about this question.
Thanks in advance,

Hi,
1) I think vector subscripting is faster than the solution below.
2) I don't understand the question, but it may be an idea to look at
?tableSlice and ?tableMargin in the gRbase package.

Harry,
I you use dummy variables, then you can only use (n-1) dummy variables
if your variable has n levels. Otherwise you introduce
multicollinearity! If you use n dummy variable then you can express one
dummy variable as a linear combination of the others.
Make use of a factor variable. That

Here is one way:

sets - lapply(1:100, function(x){
# create your set of data
runif(100) # test data

# put into matrix for 'matplot'

sets.m - do.call(cbind, sets)
matplot(sets.m, type='l')
Intro to R should tell you. A vector is basically a one-dimensional
object (addressed x[i]) and an array has multiple dimensions
(addressed x.array[i,j,k]). What confusion do you have? Think of a

I asked this as part of a previous message, but never really figured
out a usable solution. So this is a second attempt.

probability that the class is true. That

When I open that link in OpenOffice.org Writer and then save in Text
encoded format with Unicode encoding, the diacriticals (is that the
correct font-ish term?) seem to remain intact wehn re-opended. When I
read that file in, not with scan() but with readLines(), here is what

Thanks Steve,
I'm halfway there with:
foo - cbind(foo, range_group=cut(foo$score, breaks=c(.9, .8, .7, .6,
.5, .4, .3, .2, .1)))
with(foo, tapply(score, list(range_group), mean))
This works, but I only get one of the 3 columns I need, mean(score).
I'm not sure how to get the other two.

Dear Scott (and all),
Thanks for sharing your idea - it helped me solve the problem. The issue
was actually the nmfe6.bat itself - there was plenty of references
such as %dir%, %nmdir%, etc. I replaced them all with full paths.
Additionally, I put all the PATH settings from NMdirectories.bat
You followed only the ones you thought were important, but failed...

of even trying to do so.) and failed ...

contained the answer, and now ...

have sampled sites at a variety of dates. I want to use this data,
and get a running average of the sampled values for the current and
previous date.
I originally thought something like ddply would be ideal for this,
I used the readDOC function in tm.

No, you did not. To show what David, Jim, or I are talking about, consider
this example:
x1=rnorm(100,5,1)
x2=rnorm(100,3,2)
e=rnorm(100)
y1=x1+e
y2=2*x2+e
x=data.frame(x1,x2)
y=data.frame(y1,y2)
results=list
for(i%in%length(x)){
print(summary(lm(y[,i]~x[,i])))
}
