SVTable-class {geva} | R Documentation

## Summary-Variation Table

### Description

The `SVTable` class stores a `matrix` composed by two columns: `S` (for summary) and `V` (for variation).

This class is inherited by `GEVASummary`.

### Value

A `SVTable` object

### Slots

`sv`

  `matrix` composed by two columns: `S` (summary) and `V` (variation)

### Methods

Alternative accessors

`summary(object, ...)`

  Returns the `S` column

`sv.data(object)`

  Equivalent to returning this object itself

`variation(object, ...)`

  Returns the `V` column

Constructor

`svtable(S, V, row.names = NULL)`

  Creates a SVTable from the vectors `S` and `V`

Conversion and coercion

`as.data.frame(x, ...)`

  Converts this object to `data.frame`

`as.matrix(x, ...)`

  Converts this object to `matrix`

`as.SVTable.data.frame(x, row.names = rownames(x), ...)`

  Converts a `data.frame` to a `SVTable`

`as.SVTable.matrix(x, row.names = rownames(x), ...)`

  Converts a `matrix` to a `SVTable`

`as.SVTable(x, ...)`

  Returns the same object

Dimension accessors

`dimnames(x)`

  Gets a `list` with the row and column names from the `sv` slot.
  Individual dimension names can also be accessed through `rownames` and `colnames`

`dim(x)`

  Gets the dimensions from the `sv` slot

`length(x)`

  Returns the number of rows in the `sv` slot

`names(x)`

  Always returns `c('S', 'V')`

Formatting and evaluation

`format(x, ...)`

  Generic `format` implementation for `SVTable`

`with(data, expr, ...)`

  Generic `with` implementation for `SVTable`

Plotting

`plot(x, y, ...)`

  Draws a SV-plot. The horizontal axis is for summary (S) and the vertical axis is for variation (V)

`points(x, ...)`

  Draws the SV points in the plot

Subsetting

`head(x, n = 6L, ...)`

  Returns the first parts of the matrix contents

`tail(x, n = 6L, ...)`

  Returns the last parts of the matrix contents

Validation

`is.na(x)`

  Generic `is.na` implementation for `SVTable`

### Note

The matrix from `sv` slot can be `numeric`, `character`, or any other supported type by `matrix`. The same slot from `GEVASummary`, however, is always a numeric `matrix`.

### Examples

    ## Creates a SV-table where:
    # - S has elements from 1 to 10; and
    # - V has elements from 10 to 1
    svtab <- svtable(seq.int(1, 10), seq.int(10, 1))
