|
|
|
27 This tool expects input datasets consisting of tab-delimited columns (blank or comment lines beginning with a # character are automatically skipped).
|
|
|
28
|
|
|
29 .. class:: infomark
|
|
|
30
|
|
|
31 **TIP:** If your data is not TAB delimited, use *Text Manipulation->Convert delimiters to TAB*
|
|
|

|
33 .. class:: infomark
|
|
|
34
|
|
|
35 **TIP:** Computing summary statistics may throw exceptions if the data value in every line of the columns being summarized is not numerical. If a line is missing a value or contains a non-numerical value in the column being summarized, that line is skipped and the value is not included in the statistical computation. The number of invalid skipped lines is documented in the resulting history item.

39 **USING R FUNCTIONS:** Most functions (like *abs*) take only a single expression. *log* can take one or two parameters, like *log(expression,base)*
|
|
|
40
|
|
|
41 Currently, these R functions are supported: *abs, sign, sqrt, floor, ceiling, trunc, round, signif, exp, log, cos, sin, tan, acos, asin, atan, cosh, sinh, tanh, acosh, asinh, atanh, lgamma, gamma, gammaCody, digamma, trigamma, cumsum, cumprod, cummax, cummin*

45 **Syntax**
|
|
|
46
|
|
|
47 This tool computes basic summary statistics on a given column, or on a valid expression containing one or more columns.
|
|
|
48
|
|
|
49 - Columns are referenced with **c** and a **number**. For example, **c1** refers to the first column of a tab-delimited file.
|
|
|
50
|
|
|
51 - For example:
|
|
|
52
|
|
|
53 - **log(c5)** calculates the summary statistics for the natural log of column 5
|
|
|
54 - **(c5 + c6 + c7) / 3** calculates the summary statistics on the average of columns 5-7
|
|
|
55 - **log(c5,10)** summary statistics of the base 10 log of column 5
|
|
|
56 - **sqrt(c5+c9)** summary statistics of the square root of column 5 + column 9
|
