Working example:
----------------------
library("emdbook")
fn <- function()
{
browser()
y <- 2
print(deltavar(y*b2, meanval=c(b2=3), Sigma=1) )
}
x <- 2
print(deltavar(x*b1, meanval=c(b1=3), Sigma=1) )
y<-3
fn()
------------------------
running this returns 4 for the first function call, which is fine.
For the call of deltavar in fn(), I get 9, i.e. the function uses y<-3
instead of the local y<-2. If y<- is commented, deltavar returns an error.
So why is the function not using the local variable and how do I make it
use it?
