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?

The comma in "if (all(abs(w - w0) < 0,01))" strongly suggests that we have a locale problem (something is messing with LC_ALL and/or LC_NUMERIC). We have seen some of these unexpected locale changes on Microsoft platforms earlier -- as I keep saying: Gnome sometimes tries too hard to be like Windows... -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

It's a locale problem. I can reproduce this bug by relaunching my GNOME session with the Spanish locale. Numerical values are getting mangled because, in Spanish, decimals are represented with "," and (I'm guessing after a quick look at gnumeric) scientific notation requires a "+" or "-" prefix. Please submit a bug report. Thank you for your patience.
