I've got something that might be a clue to understand
the strange behaviour of lda in R --gui="gnome":
in R --vanilla:
library(MASS)
load("mod23puriflda.rda")
a <- lda.default(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F)
works fine. I save lda.default as a local rda file:
Then in R --vanilla --gui="gnome"
library(MASS)
load("mod23puriflda.rda")
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[,
Does not work, BUT:
load("milda.nognome.rda")
a <-
milda.nognome(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F,method="moment")
WORKS!!
and, still in R --vanilla --gui="gnome", I save lda.default to another
rda file:
load("milda.gnome.rda")
a <- milda.gnome(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F)
Error in milda.gnome(x = mod23puriflda[, 2:5], grouping = mod23puriflda[,
:
length of dimnames[2] not equal to array extent
In addition: Warning message:
variables are collinear in: milda.gnome(x = mod23puriflda[, 2:5], grouping
= mod23puriflda[,
Does not work !!
Therefore, gnome is really changing something, but what?
