Displays density of assets returns as a histogram and/or as log density plot.

1 2 3 4 | ```
assetsHistPlot(x, col = "steelblue", skipZeros = FALSE, ...)
assetsLogDensityPlot(x, estimator = c("hubers", "sample", "both"),
labels = TRUE, ...)
``` |

`x` |
any rectangular time series object which can be converted by the
function |

`skipZeros` |
a logical, should zeros be skipped in the histogram plot of the return series ? |

`col` |
a character string, defining the color to fill the boxes. |

`estimator` |
a character string naming the type of estimator to fit the mean
and variance of the normal density. This may be either |

`labels` |
a logical flag, if |

`...` |
optional arguments to be passed. |
