[R] R gnome and lda: found the difference

[Martyn Plummer]

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.
