function that load variables

Perhaps you mean to use

load(...., envir = .GlobalEnv)

Currently you load up the variables in the function environment but
then they are thrown away when the function ends.

Dear all,
I have saved few variable names into local files,
I wanted to make a function that load this files and "generates" the

variable names into my working environment. I have tried to do that as
a function but my problem is

that this function does not return the variable names


load_data<-function(path,Reload=FALSE){

??? if (Reload==TRUE){

??? ? print("Loading results")

??? ? # FirstSet
??? ? load(file=paste(path,'first',sep=""))
??? ? first<-Set

??? ? # SecondSet
??? ? load(file=paste(path,'second',sep=""))
??? ? second<-Set

..................(part omittted here)

??? ? save( first, second,....(part omitted here)...,????

file=paste(path,'Results',sep=""))

??? }

??? return (load(file=paste(path,'Results',sep="")))

}

so my idea was the following:
I call the function and it retuns the values first,second,... loaded

into the current working space.

If I want to refresh them, something has changed to the firstDataSet

I set the function's variable Reload=True and thus all the data are
refreshed.

The problem is not that the return statement I ahve at the end of the

function does not return the loaded variable to the working environment
but only the status of the load command.

Do you know how I can change that so my function returns also Loaded

Variable names to the environment?
