It's always good to start a new session when you don't understand what's
wrong, because sometimes your code is correct, but you use old data
without knowing it :)

Dear All: good morning
I am trying to graph the function y=f(x)=1/x over the interval (-5,5). But
I am getting an error message. Please see below.
I am getting the error message: *Error in xy.coords(x, y, xlabel, ylabel,
log) : *
* 'x' and 'y' lengths differ*
You have "y < 1/x" rather than "y <- 1/x"! So "y" is not assigned and
presumably you have some old "y" variable in your global environment that
is used and does not match the length of "x".
x
x <- seq(-5, 5, 0.01)
y < 1/x
plot(x,y, type='l', xlim=c(-5, 5), ylim=c(-5, 5), xlab = "x", ylab = "f(x)
= 1/x", lwd = 2, col ="red")
abline(h=0, lty=2, col = "blue")
abline(v=0, lty=2, col = "blue")
axis(1)
axis(2)
title(main="The Graph of f(x) = 1/x")
any help will be highly appreciated.
with thanks
abou
