Dear R People:
How are you?
I would like to look at the underlying C code from the program C_ARIMA_Like
in the stats package.
However, since that is a base package, I'm not entirely sure how to access
this.
When I used the .C(C_ARIMA_Like)
it says that the C_ARIMA_Like cannot be found.

Yes and no. There are "lists" that can hold anything, but for normal objects
there are no "pass by reference" semantics. The exception to that is
environments, but that is really a limited scope of usability. That is, you can
receive a changed object in the calling scope and choose to overwrite

Hi,
I'd do it like this, making use of data frames and the data argument to lm.
traindata <- data.frame(price=price, predictor1=predictor1,
predictor2=predictor2)
testdata <- data.frame(predictor1=3, predictor2=5)
predict(lm(price ~ ., data=traindata), testdata)
Note that you don't have to speci
Solved! Here is the solution in case it helps others:
The easiest way to get past the issue of matching up variable names from a
matrix of covariates to newdata data.frame column names is to put your
input data into a data.frame as well. Try this
price = c(10,18,18,11,17)
predictors = cbind(c(5,6

I want to perform a multiple regression in R and make predictions based on
the trained model. Below is an example code I am using:
price = c(10,18,18,11,17)
predictors = cbind(c(5,6,3,4,5),c(2,1,8,5,6))
predict(lm(price ~ predictors), data.frame(predictors=matrix(c(3,5),nrow=1)))
So, based on th
Good afternoon.
The question is: does R support pointer like structures? The specific
problem is:
a function supporting operations on a set of data frames with similar
structures.
I have a set of data frames with similar structures. I wish to perform
similar operations on those data frames. I
This is not a big problem. It just means your system does not have a
default program to open .swf files. If you associate, say, a movie
player, with .swf, this problem will go away.

Yes, this is the good one Arun! Thank you very much.
I tried each solution but yours was the best. It works well.
Thanks anyway for all your replies!

Well, start by using the correct syntax -- you've misplaced your quotes.
Then look at existing code, e.g.

Hi,
I need to merge two data sets but I need them to match two columns, not just
one. For example:
Hi,
If 'dat1` and 'dat2` are the two datasets.
merge(dat1,dat2,by=c("plant.species","insect.species"),all=TRUE)

Hi,
You can try ?merge() or ?join() from library(plyr)
