[R] R gnome and lda: found the difference

[Agustin Lobo]

Saving lda.default as text files from within gui="none" and from within
gui="gnome" 
and comparing afterwards with diff, I get:

alobo at humboldt:> diff lda.default.gnome.txt lda.default.nognome.txt
1c1
< function (x, grouping, prior = proportions, tol = 1, method =
c("moment",
---
> function (x, grouping, prior = proportions, tol = 1e-04, method =
c("moment",
61c61
<             if (all(abs(w - w0) < 0,01))
---
>             if (all(abs(w - w0) < 0.01))
109c109
<         dist <- 0 * dist - matrix(log(prior), n, ng, byrow = TRUE)
---
>         dist <- 0.5 * dist - matrix(log(prior), n, ng, byrow = TRUE)

It's clear then that R with the gnome gui uses a different copy
of lda.default, 
but the output of .path.package is identical:
> .path.package()
[1] "/usr/local/lib/R/library/MASS"  "/usr/local/lib/R/library/ctest"
[3] "/usr/local/lib/R/library/base" 

I don't think I can go further on my own, is this something that I should
submit as a bug?
