Hint: MASS is a *package*. You want to view its *source*.
Same with most other R packages.
Consider the following:
library(MASS)
lda
function (x, ...)
UseMethod(lda)
environment: namespace:MASS
methods(lda)
[1] lda.data.frame lda.defaultlda.formulalda.matrix
Now type lda.data.frame or lda.default, etc., at a command prompt to
see the corresponding R code.

Hi Jason, Spencer,
Thanks for the prompt response. The strange thing about MASS is that it's
not in Package Sources as most of other R packages are. It seems to come
with the binary R installation. I checked out the Rxx/library/MASS on my
laptop, there are source code (script) for Venables

least this is true on my Linux setup). The exact location of that file
you'll have to determine by searching the directory/folder
With R 1.7.1 on Windows 2000, I got fine R source code for each of the 4
options. What version of R and what exactly did you do? I can't
reproduce your error.
hope this helps. spencer graves

Try typing lda.default at the prompt. That should get you started. Also see:
methods(lda)
as lda.default isn't the only bit of code used in lda()
Alternatively, grab the source from CRAN and read it at your leisure.

You are using a *beta* version of R 1.8.0 and in that version
lda.default is not visible to the user (hidden in a namespace). You can
access it though by using the ::: (triple colon) operator, as in
library(MASS)
MASS:::lda.default
Actually, the first library() call is not necessary.
