I'm learning so ignore anything amusing.
I was computing a quad equation using A, B, C variables with assigned values.
When I gained the answer, that being, when it calculate the value of X successfully, I then stupidly assigned this value to X itself.. like this 'X <- 0.6289' .
My problem is, now every time I alter the variable values (a, b, c) X does not change in relation.
I have managed to remove X from the list of variables present in the environment section. However I still unsure how to turn X back into it's former, vacant, self.
Even if I'm being daft I would like to know.
All thoughts welcome.
