R: Histogram and Density Plots

HistogramPlot {fBasics} | R Documentation

## Histogram and Density Plots

### Description

Returns a histogram, a density, or a logarithmic density plot.

List of Functions:

`histPlot` | Returns a tailored histogram plot,
`densityPlot` | Returns a tailored kernel density estimate plot,
`logDensityPlot` | Returns a tailored log kernel density estimate plot.

### Usage

    histPlot(x, labels = TRUE, col = "steelblue", fit = TRUE,
        title = TRUE, grid = TRUE, rug = TRUE, skip = FALSE, ...)
    densityPlot(x, labels = TRUE, col = "steelblue", fit = TRUE, hist = TRUE,
        title = TRUE, grid = TRUE, rug = TRUE, skip = FALSE, ...)
    logDensityPlot(x, labels = TRUE, col = "steelblue", robust = TRUE,
        title = TRUE, grid = TRUE, rug = TRUE, skip = FALSE, ...)

### Arguments

`col` | the color for the series. In the univariate case use just a color name like the default, `col="steelblue"`, in the multivariate case we recommend to select the colors from a color palette, e.g. `col=heat.colors(ncol(x))`.
`fit` | a logical flag, should a fit added to the Plot?
`grid` | a logical flag, should a grid be added to the plot? By default `TRUE`. To plot a horizontal lines only use `grid="h"` and for vertical lines use `grid="h"`, respectively.
`hist` | a logical flag, by default TRUE. Should a histogram to be underlaid to the plot?
`labels` | a logical flag, should the plot be returned with default labels and decorated in an automated way? By default `TRUE`.
`rug` | a logical flag, by default TRUE. Should a rug representation of the data added to the plot?
`skip` | a logical flag, should zeros be skipped in the return Series?
`robust` | a logical flag, by default TRUE. Should a robust fit added to the plot?
`title` | a logical flag, by default TRUE. Should a default title added to the plot?
`x` | an object of class `"timeSeries"` or any other object which can be transformed by the function `as.timeSeries` into an object of class `timeSeries`. The latter case, other then `timeSeries` objects, is more or less untested.
`...` | optional arguments to be passed.

### Value

displays a time series plot.

### Examples

    ## data -
       SPI <- LPP2005REC[, "SPI"]
       plot(SPI, type = "l", col = "steelblue", main = "SP500")
       abline(h = 0, col = "grey")

    ## histPlot -
       histPlot(SPI)

    ## densityPlot -
       densityPlot(SPI)
