I am new to the TeX Stackexchange, so I want to apologize beforehand if I do not comply with the question-writing customs/rules.
My question is about the graphing program for LaTeX Ipe. I have downloaded it from the webpage, and when using it I am having trouble to insert math-mode text. For example, I click the "insert math" option, and write \mathbb{R}
and it does not print out. Instead an error pops out saying:
***! Undefined control sequence.
<recently read> \mathbb
l.57 $\mathbb
{R}$%
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
Overfull \hbox (170.0pt too wide) in paragraph at lines 61--62

I am also having trouble to print \mathscr{R}
and other symbols.
Furthermore, the math appears to being printed in "inline" mode, instead of in "display mode". Can anyone please help me with this?
Thank you very much, and again, I apologize if the format of my question is not in line with the norms of the site.
\mathbb
is from theamssymb
package, so adding\usepackage{amssymb}
to the preamble of your document should solve the problem.
