`dataframe`	data.frame. Data with adverse events.
`subjectVar`	character. Variable classified to major and minor category (subject ID).
`minorVar`	character. Name of minor category variable within dataset. (i.e. specific adverse event)
`majorVar`	character. Name of major category variable within dataset. (i.e. body system adverse event belongs to)
`occurrenceVar`	character. Name of occurrence variable within dataset. It indicates the different occurrences of a minor category for a given `subjectVar` (date or order in which event happened). This variable is assumed to be unique for given subject and given `minorVar`.
`stratVar`	character. Name of stratification variable within dataset. (i.e. treatment)
`denomSub`	numeric vector. Contains the number of unique subjects in each `stratVar` level. It should have the same names and length as `levels(stratVar)`. Defaults to ‘NULL’, where values will be calculated accordingly from the dataset.
`fileName`	character. Name of output file, defaults to ‘NULL’.
`labelLen`	numeric. Maximum length of grid labels.
`pvalue`	numeric. If for a given major and minor category, the proportion test gives a p-value less than `pvalue`, then this category will be highlighted. Defaults to ‘0.5’.
`keepPvalue`	numeric. Only categories with a p-value (according to the proportion test) less than `keepPvalue` will be displayed.
`minDisplayNum`	numeric. Only categories with a total frequency more than `minDisplayNum` will be displayed. Defaults to ‘2’.
`majorGrid`	numeric vector. Grid of major category.
`minorGrid`	numeric vector. Grid of minor category.
`plotGrid`	logical. Set to ‘TRUE’ to plot grid lines.
`gridDig`	numeric. Set the number of digits used to round the grid digits.
`titleOffsetKoef`	numeric. The vertical distance the title should stay from the graph.
`titleOffsetX`	numeric. The horizontal distance the title should stay from the graph.
`minorToMajorKoef`	numeric. The distance the bars for the minor category should be longer than the bars for the major category.
`sparseKoef`	numeric. How farther away the graphs for different `stratVar` values should be located on the diagram.
`graphWidth`	numeric. Width of plot, the default is ‘8’.
`graphHeight`	numeric. Height of plot, the default is ‘11’.
`gridCex`	numeric. Relative size of the grid digits.
`labelCex`	numeric. Relative size of the labels.
`titles`	named character vector. Titles for each frequency display. It's names should be levels of treatment.
