I have a function that gets two parameters, one is used as a subscript for
the column names and another is used as an index into the chosen column.
For example:
my_func - function(subscr,

I'm still working on functions to make it easier for students to
interpret regression predictions. I am working out a scheme to
more easily create newdata objects (for use in predict functions).
This has been done before in packages like Zelig, Effects,
rms, and others. Nothing is

Why does this need to be in base? Implement it in a package.

Sometimes I have hundreds of CSV files scattered in a directory tree,
resulting from experiments' executions. For instance, giving an example

several design parameters such as cache size (possible values: 2, 4, 8

Victor,
I understand you as follows
The first two columns of the desired combined dataframe are the last two
levels of the pathname to the csv file.
The columns in all the data.csv files are the same, namely, there is

one column, and it is named PERF.
If so, the following

I am running into a wall getting my system to work with rcpp and inline.
Following Dirk's advice on stackoverflow, I hope someone is able to help
me.
My steps were to install MinGW 32 bit first, then installing Rtools, I
disabled MinGW's entry in the PATH.

There is a dedicated mailing list for Rcpp: rcpp-devel.

A bit late and possibly tangential.
The mmap package has something called struct() which is really a row-wise array
of heterogenous columns.
As Simon and others have pointed out, R has no way to handle this natively, but
mmap does provide a very measurable performance gain by orienting rows
