Hi - I'm having a really hard time w/understanding R's get function, and would appreciate any help with this.
Specifically, I'm using a for loop to call a function. I'd like the function to have access to the variable being incremented in the for-loop, i.e. t.fn <- function() return( get( "i" ) ) t.fn2 <- function() { for ( i in 1:5 ) cat( t.fn(), "\n" ) } However, I keep getting err msg's from the 'get' function about how it can't find the 'i' variable. I've tried various combinations w/in the get fn, i.e. passing inherits=T (should be the default val according to R's help) and envir=sys.frame(). As I understand it, 'get' should search the enclosing environments, which I assume would be the call-stack of the functions. If not, could someone clarify? Thanks, Peter p.s. when I define t.fn to be: t.fn<- function() { for ( j in sys.nframe():0 ) cat( j,":",ls( sys.frame( j ) ), "\n" ) } and call that in t.fn2(), I do eventually see the 'i' variable, i.e. > t.fn2() 2 : j 1 : i 0 : test t.fn t.fn2 t.fn3 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
