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))
* 109c109
< 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
