Subject: [Rd] Gnome causes different behaviour of some R functions (PR#1321)

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

 <         dist <- 0 * dist - matrix(log(prior), n, ng, byrow = TRUE)
 ---
>         dist <- 0.5 * dist - matrix(log(prior), n, ng, byrow = TRUE)


While lda.default works fine within R --gui="none", it produces the following
error
from within R --gui="gnome" for the same data:

> a
<-lda.default(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F,method="moment")
Error in lda.default(x = mod23puriflda[, 2:5], grouping = mod23puriflda[,
: 
        length of dimnames[2] not equal to array extent
In addition: Warning message: 
variables are collinear in: lda.default(x = mod23puriflda[, 2:5], grouping
= mod23puriflda[, 

This problem is not particular to lda.default. The following code, which works
fine from within R --gui="none", fails from within within R --gui="gnome":

> x1<-rnorm(20)
> x2<-rnorm(20)
> boxplot(list(x1=x1,x2=x2))
Error in if (any(out[nna])) stats[c(1, 5)] <- range(x[!out], na.rm = TRUE) : 
	missing value where logical needed
