Statistic

Statistics pre-processes data prior to plotting. For example, the "box" statistic calculates the quartiles, and the "count" statistics calculates the number of occurrences of each unique value.

List of Statistics

• gg.stats.id - do not apply any statistics
• gg.stats.bin - count the number of objects per bin
• gg.stats.box - calculate quartiles and outliers to be use for a box plot
• gg.stats.count - counts the number of occurrences of each value
• gg.stats.stack - used for stacked bar charts
• gg.stats.sum - calculate the sum for each group
• gg.stats.mean - calculate the mean for each group
• gg.stats.unique - counts the number of unique value in each group
• gg.stats.ratio - normalizes each group to sum to 1, and calculate the proportion of each data point (this is useful for pie chart creation, for example)
