| 3 | 1 | h2. The problem |
|
| 4 | 1 | ||
| 5 | 1 | The @verbatim@ environment interferes with AMC LaTeX package, so that it is impossible to use it inside @question@ or @questionmult@ environments... As an example, the following code won't compile: |
|
| 6 | 1 | <pre> |
|
| 7 | 1 | \begin{question}{program} |
|
| 8 | 1 | What is the return value of the following R code? |
|
| 9 | 1 | \begin{verbatim} |
|
| 10 | 1 | sum(sapply(1:2^2,function(x) { x/2 })) |
|
| 11 | 1 | \end{verbatim} |
|
| 12 | 1 | \begin{choices}[o] |
|
| 13 | 1 | \wrongchoice{2.5} |
|
| 14 | 1 | \correctchoice{5} |
|
| 15 | 1 | \wrongchoice{NaN} |
|
| 16 | 1 | \end{choices} |
|
| 17 | 1 | \end{question} |

| 22 | 1 | h3. Escaping |
|
| 23 | 1 | ||
| 24 | 1 | For very small texts, it is possible to escape all characters that have a special meaning for LaTeX. However, this can become quickly tedious... |
|
| 25 | 1 | <pre> |
|
| 26 | 1 | \begin{question}{program} |
|
| 27 | 1 | What is the return value of the following R code? |
|
| 28 | 1 | \begin{center} |
|
| 29 | 1 | \texttt{sum(sapply(1:2\textasciicircum 2,function(x) \{ x/2 \}))} |
|
| 30 | 1 | \end{center} |
|
| 31 | 1 | \begin{choices}[o] |
|
| 32 | 1 | \wrongchoice{2.5} |
|
| 33 | 1 | \correctchoice{5} |
|
| 34 | 1 | \wrongchoice{NaN} |
|
| 35 | 1 | \end{choices} |

| 39 | 1 | h3. UseVerb |
|
| 40 | 1 | ||
| 41 | 1 | You can also record some one-line verbatims with the @fancyvrb@ package (define your verbatim outside â before â @\onecopy@): |
|
| 42 | 1 | <pre> |
|
| 43 | 1 | \SaveVerb{theRcode}'sum(sapply(1:2^2,function(x) { x/2 }))' |
|

| 45 | 1 | ... |
|
| 46 | 1 | ||
| 47 | 1 | \begin{question}{program} |
|
| 48 | 1 | What is the return value of the following R code? |
|
| 49 | 1 | \begin{center} |
|
| 50 | 1 | \UseVerb{theRcode} |
|
| 51 | 1 | \end{center} |
|
| 52 | 1 | \begin{choices}[o] |
|
| 53 | 1 | \wrongchoice{2.5} |
|
| 54 | 1 | \correctchoice{5} |
|
| 55 | 1 | \wrongchoice{NaN} |
|

| 60 | 1 | h3. Verbatim boxes |
|
| 61 | 1 | ||
| 62 | 1 | For larger verbatims, the @verbatimbox@ package can help you: |
|
| 63 | 1 | <pre> |
|
| 64 | 1 | \begin{myverbbox}{\Rcode} |
|
| 65 | 1 | sum(sapply(1:2^2,function(x) { x/2 })) |
|
| 66 | 1 | \end{myverbbox} |
|

| 68 | 1 | ||
| 69 | 1 | ... |
|
| 70 | 1 | ||
| 71 | 1 | \begin{question}{program} |
|
| 72 | 1 | What is the return value of the following R code? |
|
| 73 | 1 | \begin{center} |
|
| 74 | 1 | \Rcode |
|
| 75 | 1 | \end{center} |
|
| 76 | 1 | \begin{choices}[o] |
|
| 77 | 1 | \wrongchoice{2.5} |
|

|
| 79 | 1 | \wrongchoice{NaN} |
