I'm puzzled by the discourse in this thread. Briefly, dput() and dget() seem to work just fine for me.
I tried
> junk <- list(x=rnorm(20),y=sample(1:100,12,TRUE)) > dput(junk,"junk.dat")
in Splus (Version 6.1.2 Release 2 for Sun SPARC, SunOS 5.6 : 2002)
and then in R
> junk <- dget("junk.dat")
R version:
platform sparc-sun-solaris2.9 arch sparc os solaris2.9 system sparc, solaris2.9 status major 1 minor 9.1 year 2004 month 06 day 21 language R
There were no complaints, and typing ``junk'' in the R window and in the Splus window appeared to produce indentical results.
So what's the problem?
