This function provides a number of descriptives about your data, similar to what SPSS's DESCRIPTIVES (often called with DESCR) does.

1 2 3 4 5 6 |

`x` |
The vector for which to return descriptives. |

`digits` |
The number of digits to round the results to when showing them. |

`errorOnFactor` |
Whether to show an error when the vector is a factor, or just show the frequencies instead. |

`include` |
Which elements to include when showing the results. |

`maxModes` |
Maximum number of modes to display: displays "multi" if more than this number of modes if found. |

`t` |
Whether to transpose the dataframes when printing them to the screen (this is easier for users relying on screen readers). |

`conf.level` |
Confidence of confidence interval around the mean in the central tendency measures. |

`quantileType` |
The type of quantiles to be used to compute the interquartile range (IQR). See |

Note that R (of course) has many similar functions, such as `summary`

,
`describe`

in the excellent `psych`

package.

The Hartigans' Dip Test may be unfamiliar to users; it is a measure of uni- vs. multidimensionality, computed by `dip.test`

from the `dip.test`

package. Depending on the sample size, values over .025 can be seen as mildly indicative of multimodality, while values over .05 probably warrant closer inspection (the p-value can be obtained using `dip.test`

; also see Table 1 of Hartigan & Hartigan (1985) for an indication as to critical values).

A list of dataframes with the requested values.
