Hi Everyone ,
I am having an issue with the following code and would need kind assistant.
For a specific reason , I would need to create a new environment for
variables within the function and use them and I am having issue with it on
the project I am doing.
The issue is that no matter what I do , I am getting the following error on
"Error in eval(expr, envir, enclos) : object 'x3' not found"
and it is the x3 that is within the groupedData(y~-1 + x3 | g
and not in the data.frame
fun1 <- function()
{
ee <- new.env()
t <- 10
x <- 5
g<- 8
assign("x2",x,envir = as.environment(ee))
x3 <- get("x2" , envir = as.environment(ee))
if(t == 10)
{
if(g == 8)
{
data.fr <- groupedData(y~-1 + x3 | g,
data=data.frame(y,x3,h, dummy))
}
}
}
Thanks and Regards
Billy

It's a good idea to post "minimal" examples; distractions are distracting.> > data.fr <- groupedData(y~-1 + x3 | g, > data=data.frame(y,x3,h, dummy))What is groupedData? We also ask for self-contained examples, and that isn't in the default packages. Are you talking about the function in nlme? If so, do you expect it to make use of ee? It never sees ee. And where does y come from?
