Dear George,
Perhaps redefining Fn as
Fun2 <- function(x) ifelse(x==0,1,sin(x)/x)
could help. Now, for the symbolic part (I'm not sure if understood
correctly), try ?curve as follows:
curve(Fun2(x),-10,10)
HTH,
Jorge

Hello, R subscribers.
I would like to define a function like this one:
Fun <- function(x)sin(x)/x
with value 1 at x=0. How can I do that?
Is there a way to plot it "symbolically", without using x as a vector?
e.g.
x <- seq(from=-10, to=10, length=100)
plot(x, Fun(x))
Thank you in advance.
