[R] save(iris,file=

[Gabor Grothendieck]

I tried it using file and it seems to work for saving:

> data(iris)
> con <- file("clipboard","w")
> save(iris,ascii=T,file=con)
> close(con)
> readLines("clipboard")
... lengthy output follows which seems correct ...

but not for loading:

> con <- file("clipboard","r")
> 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:

> save(iris,ascii=T,file="myiris.rda")
> rm(iris)
> load("myiris.rda")
> ls()
... iris is back ...

As should be evident , you thought wrong (and you are thinking in the
blinkered Windows way, too).

On Windows, file() can take a filename "clipboard" in text mode only.
load() and save() are not using file(), but you could probably use it
explicitly in ASCII mode.

Don't assume your own errors are bugs in other peoples' work: it is 
discourteous.
