Re: [R] How to make the assignment in a for-loop not affect variables outside the loop?

Try n=10 b=1 local( for(i in 1:n) { n=3 print(n) b - b*i } ) print(n) print(b) or n=10 b=1 local( for(i in 1:n) { n=3 print(n) assign(b, b*i, env=.GlobalEnv)

2009/11/22 Uwe Ligges lig...@statistik.tu-dortmund.de: Either use local as in: n=10 local(for(i in 1:n){     n=3     print(n) }) print(n) 'local()' makes everything inside it unavailable outside of it. Is there a way to make 'n' unavailable outside but still make 'b' available outside

[R] How to make the assignment in a for-loop not affect variables outside the loop?

I know that R is a dynamic programming language. But I'm wondering if there is a way to make the assignment in a for-loop not affect variables outside the loop. n=10 for(i in 1:n){ + n=3 + print(n) + } [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 [1] 3 print(n) [1] 3

Either use local as in: n=10 local(for(i in 1:n){ n=3 print(n) }) print(n) or write a function that is evaluated in its own environment: n=10 MyLoopFoo - function(){ for(i in 1:n){ n - 3 print(n) } } MyLoopFoo() print(n) Uwe Ligges Peng Yu wrote:
