Hello,

Why can't I compile the \mathbb{R} in LaTeX/MikTeX.
I'm using Win2k and compiling with PdfLaTeX.

The Error: "Undefined control sequence"

Please help me.

What makes you expect this should work? Have you included either the
package amsfonts or amsmath?

Put \usepackage{amssymb} in your preamble, and remember that \mathbb{R} has
to be in maths mode.

\usepackage{amsmath,amssymb}
