normally that works,
BUT <<- is BAD and not accepted in some repositories as Bioconductor.
one<-function(){
a<-"variable passed"
return(a)
}
x <- one()
two<-function(x){
print(x)
}

Please don't. Function arguments are good... global variables are bad.
one <- function(){
result <- list( a="variable passed" )
result
}
two <- function( v ){
print( v$a )
}
x <- one()
two( x )

So you have to execute one() first?

If I execute dos(), then the error message is:

How would one do that?

Well, what would be really helpful is to restrict the scope of all
non-function variables, but keep a global for scope of all function
variables. Then, you still have access to all loaded functions, but you
don't mix up variables.
How would one do that?

Thanks,
I will have a look at it.

Hi Sebastian,

the scope of variables. It provides a more intuitive (at least to me)
way of packaging variables and functions up into environments that can
be related in a hierarchy.

Thank Gabor and Duncan,
That will be helpful.

Yes, but you probably shouldn't. You would do it by setting the
environment of the function to something that doesn't have the global

Dear R-users,
Is there a way I can prevent global variables to be visible within my
functions?

Hi Keith,
A more specific example of what you're looking for might be
helpful--ie do you want to read global variables or set them? You
probably want to look at environments and closures; ?"<<-" and ?assign
are good starting points (the latter has an example of "Global
Assignment within a function
I think you are looking for a macro facility. See defmacro in gtools
which is based on Thomas Lumley's function of the same name whose
article you can find in back issues of R News.

Y'all,
I would like to have most of the variables in my function to be global
instead of local. I have not found any references that tell me now to
do that. If I have missed a reference please excuse me and tell me
what I have missed.
Thanks,
Keith Jones
