Re: [R] Error running lda example from Help File (MASS library )

[Greg Riddick]

The actual code for the lda example is below.  If anyone can reproduce the
error,
let me know.  Thanks.


library(MASS)

Iris <- data.frame(rbind(iris3[,,1], iris3[,,2], iris3[,,3]),
   Sp = rep(c("s","c","v"), rep(50,3)))
train <- sample(1:150, 75)
table(Iris$Sp[train])
z <- lda(Sp ~ ., Iris, prior = c(1,1,1)/3, subset = train)

[R] Problem with package SNOW on MacOS X 10.5.5

[Greg Riddick]

Hello All,

I can run the "lower level" functions OK, but many of the higher level
(eg. parSApply) functions are generating errors.

When running the example (from the snow help docs) for parApply on
MacOSX 10.5.5, I get the
following error:


cl <- makeSOCKcluster(c("localhost","localhost"))
sum(parApply(cl, matrix(1:100,10), 1, sum))

Error in do.call("fun", lapply(args, enquote)) :
  could not find function "fun"



Any ideas? Do I possibly need MPI or PVM to run the "Apply" functions?

Thanks,
