Bug #2281: need to escape stuff!
1: \label{Spreadsheet_Functions}
2: The following special functions are available in the spreadsheet.
3: Please see \textbf{Referencing Cells} (\ref{Spreadsheet_Referencing_Cells})
4: for information on specifying cells and ranges.
5:
6: \begin{itemize}
7:
8: \item \texttt{\&NUM(range)} - number of non-empty cells in range
9: \index{NUM}
10:
11: \item \texttt{\&BIN(low, high, range)} - number of non-empty cells in
12: range with values between low and high
13: \index{BIN}
14:
15: \item \texttt{\&SUM(range)} - sum of the non-empty cells in range
16: \index{SUM}
17:
18: \item \texttt{\&MEAN(range)} - mean value of non-empty cells in range
19: \index{MEAN}
20:
21: \item \texttt{\&STDDEV(range)} - standard deviation of non-empty cells
22: in range
23: \index{STDDEV}
24:
25: \item \texttt{\&PROD(range)} - product of non-empty cells in range
26: \index{PROD}
27:
28: \item \texttt{\&MAX(range)} - maximum value of non-empty cell in range
29: \index{MAX}
30:
31: \item \texttt{\&MIN(range)} - minimum value of non-empty cells in
32: range
33: \index{MIN}
34:
35: \item \texttt{\&SUMMAX(n ,range)} - sum of the maximum n non-empty
36: cells in range
37: \index{SUMMAX}
38:
39: \item \texttt{\&SUMMIN(n, range)} - sum of the minimum n non-empty
40: cells in range
41: \index{SUMMIN}
42:
43: \item \texttt{\&EXT(expression)} - access to EXT function in lonnet.
44: Use \&EXT(``system.time'') to retrieve the current time.
45: \index{EXT}
46:
47: \item \texttt{\&SUMSEQ(column,sequence1,sequence2,sequence3,...)} -
48: sum the given column across the folders or sequences listed.
49:
50: When specifying a sequence use the full title. Instead of a sequence title
51: the word ``all'' can be used to sum over all sequences. Regular expressions
52: can be entered as well, if prefixed by ``regexp:''. See below for examples.
53:
54: \begin{itemize}
55:
56: \item \texttt{\&SUMSEQ(``Z'',''Chapter 1'');}
57:
58: \item \texttt{\&SUMSEQ(``Z'',''Chapter 1'',''Chapter 2'',''Chapter 3'');}
59:
60: \item \texttt{\&SUMSEQ(``Z'',''all'');} - sum over all sequences.
61:
62: \item \texttt{\&SUMSEQ(``Z'',''regexp:Large Biomolecules'');} -
63: sum over all sequences which match the regular expression
64: /Large Biomolecules/.
65:
66: \end{itemize}
67:
68: \end{itemize}
69:
70: In addition, most non-IO Perl functions work in cells.
