Description Usage Arguments Details See Also Examples

Produce complete table of nine-numbers grouped by a given column in the data plus a total row.

1 2	KH.nineNumbers.table(DT, x, groupBy, titles = NULL, rowname = NULL, decimal = "default", order = "default")

`DT`	data.table. data.table of at least one column of numbers and at least one column of factoring element to calculate statistics.
`x`	string. Name of vector containing the data to extract statistics for.
`groupBy`	string. Vector containig name of grouping factors columns.
`titles`	string. Vector of strings with 9 member as col.names of the results.
`rowname`	string. A title for the row. This is handy for attaching the output to the table from `Stats.nineNumbers.by`.
`decimal`	integer. Set precision for vectors in resultant quantile. Default is `decimal` in package.
`order`	string. Not implemented yet. Sort order of columns.

For an appropriate insight into the data 9 numbers are consulted usually. These nine numbers consist of length, minimum, lower-hinge, median, upper-hinge, maximum, mean, sd of a data vector. This function creates both a table and a row for total data.

Other Stats: KH.IQR, KH.max, KH.mean, KH.median, KH.min, KH.nineNumbers.by, KH.nineNumbers.total, KH.quant.10, KH.quant.25, KH.quant.75, KH.quant.n, KH.sd
