plot_signatures {musicatk} | R Documentation

## Plots the mutational signatures

### Description

After mutational signature discovery has been performed, this function can be used to display the distribution of each mutational signature. The `color_variable` and `color_mapping` parameters can be used to change the default color scheme of the bars.

### Usage

    plot_signatures(
      result,
      legend = TRUE,
      plotly = FALSE,
      color_variable = NULL,
      color_mapping = NULL,
      text_size = 10,
      facet_size = 10,
      show_x_labels = TRUE,
      same_scale = TRUE
    )

### Arguments

`result` | A `musica_result` object generated by a mutational discovery or prediction tool.
`legend` | If `TRUE`, the legend for mutation types will be included in the plot. Default `TRUE`.
`plotly` | If `TRUE`, the the plot will be made interactive using `plotly`. Default `FALSE`.
`color_variable` | Name of the column in the variant annotation data.frame to use for coloring the mutation type bars. The variant annotation data.frame can be found within the count table of the `musica` object. If `NULL`, then the default column specified in the count table will be used. Default `NULL`.
`color_mapping` | A character vector used to map items in the `color_variable` to a color. The items in `color_mapping` correspond to the colors. The names of the items in `color_mapping` should correspond to the uniqeu items in `color_variable`. If `NULL`, then the default `color_mapping` specified in the count table will be used. Default `NULL`.
`text_size` | Size of axis text. Default `10`.
`facet_size` | Size of facet text. Default `10`.
`show_x_labels` | If `TRUE`, the labels for the mutation types on the x-axis will be shown. Default `TRUE`.
`same_scale` | If `TRUE`, the scale of the probability for each signature will be the same. If `FALSE`, then the scale of the y-axis will be adjusted for each signature. Default `TRUE`.

### Value

Generates a ggplot or plotly object
