should `data` respect default.stringsAsFactors()?
Hi Peter,
Sorry if I was not clear. Perhaps an example will make my point:
> data(iris)
> class(iris$Species)
[1] "factor"
> write.table(iris,'data/myiris.tab')
> data(myiris)
> class(myiris$Species)
[1] "factor"
> rm(myiris)
> options(stringsAsFactors = FALSE)
> data(myiris)
> class(myiris$Species)
[1] "factor"
> myiris<-read.table("data/myiris.tab",header=TRUE)
> class(myiris$Species)

Hiya,
Probably been debated elsewhere....
I note that R's `data` function does not respect default.stringsAsFactors
By my lights, it should, especially as it is documented to call read.table, which DOES respect.
Oh, but: http://r.789695.n4.nabble.com/stringsAsFactors-FALSE-tp921891p921893.html
Compelling. I have to agree.
So, I change my mind.
By my lights, `data` should then be

...hich seems correct ...
but not for loading:

> load(con)
Error in load(con) : loading from connections not compatible with magic number
even though when I try it with real files then it works both ways:

> rm(iris)
> load("myiris.rda")
> ls()
... iris is back ...

save(iris,file="clipboard",ascii=TRUE)
...ve(iris,ascii=TRUE,file="clipboard")
Error in file(file, "wb") : `mode' for the clipboard must be `r' or `w'
Also this (where gclip is a utility found at unxutils.sourceforge.net
that copies its standard input to the clipboard):

In addition: Warning message:

context of runif()
Greetings,
I am exploring some random forest analysis methods and have come upon one
aspect I don't fully understand from any manual. The code of interest is
as follows from the randomForest package:
myiris=cbind(iris[1:4], matrix(runif(508*nrow(iris)),nrow(iris),508))
This would be following by the rfcv() function for cross-validation but I
am confused about the former syntax.
My question is why 508? Is this some arbitrary number that one just
chooses are is there some logic to the choice? I have...
