[R] can lm() automatically take in the independent variableswithout knowing the names in advance

[Leeds, Mark (IED)]

someone may know how to do what you asked but a get around is to not
read the header in the file and assign
your own variable names to each column.  This way you have control and
you don't worry about doing anything dynamically.

This is pretty easy if you are using read.table and probably also
possible with other types of in "read in file" functions.

Subject: [R] can lm() automatically take in the independent

Hello!

I am trying to use lm to do a simple regression but on a batch of
different files.

Each file has different column names.

I know the first column is the dependent variable and all the rest are
explanatory variables.

The column names are in the first line of the file.

But it seems lm() requires I know the variable names in advance?

Is there a way to dynamically read in variable names and send to lm()?

Many many thanks!!!
