Hello,
thank you for your reply.
Actually, the whole rows would have to be averaged anyways - my mistake :-)
Besides the first column name there is one other string (chr) variable

So what do you want to do with the test variable when averaging?

I need to merge two data sets but I need them to match two columns, not just
one. For example:

Thanks a lot for your input.

This is a warning and in your case would not be a problem, but it is
good to think about and the reason why it is suggested that you avoid
using attach and be very careful when you do use attach. What is
happening is that you first created a vector named 'x' in your global
workspace, you then

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.

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
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:

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

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 =
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

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
