## tidy a TukeyHSD object

### Description

Returns a data.frame with one row for each pairwise comparison

### Usage

    ## S3 method for class 'TukeyHSD'
    tidy(x, separate.levels = FALSE, ...)

### Arguments

`x` | object of class "TukeyHSD"
`separate.levels` | Whether to separate comparison into `level1` and `level2` columns
`...` | additional arguments (not used)

### Value

A data.frame with one row per comparison, containing columns

`term` | Term for which levels are being compared
`comparison` | Levels being compared, separated by -
`estimate` | Estimate of difference
`conf.low` | Low end of confidence interval of difference
`conf.high` | High end of confidence interval of difference
`adj.p.value` | P-value adjusted for multiple comparisons
