 * Support for Addins menu in RStudio to quickly insert `%in%` or `%like%` (and give them keyboard shortcuts), or to view the datasets that come with this package
 * For convience, descriptive statistical functions `kurtosis` and `skewness` that are lacking in base R - they are generic functions and have support for vectors, data.frames and matrices
+* Function `g.test` to perform the Χ<sup>2</sup> distributed [*G*-test](https://en.wikipedia.org/wiki/G-test), which use is the same as `chisq.test`
+* Function `ratio` to transform a vector of values to a preset ratio. For example:
+```r
+ratio(c(772, 1611, 737), ratio = "1:2:1")
+# [1]  780 1560  780

+* Function `p.symbol` to transform p value to their related symbol: `0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1`
 * New for frequency tables (function `freq`):
   * A vignette to explain its usage
   * Support for `table` to use as input: `freq(table(x, y))`

   * Header of frequency tables now also show Mean Absolute Deviaton (MAD) and Interquartile Range (IQR)
   * Possibility to globally set the default for the amount of items to print, with `options(max.print.freq = n)` where *n* is your preset value
 * Functions `clipboard_import` and `clipboard_export` as helper functions to quickly copy and paste from/to software like Excel and SPSS
