stat_slice {ggbio} | R Documentation

## Slice Rle/RleList to view them as bar or heatmap.

### Description

Slice Rle/RleList to different view by set lower or other parameters, then view summary for all those viewed region.

### Usage

    ## S4 method for signature 'Rle'
    stat_slice(data, ...,
              xlab, ylab, main,
              na.rm = FALSE,
              geom = NULL,
              lower=-Inf, upper=Inf,
              includeLower=TRUE, includeUpper=TRUE,
              rangesOnly = FALSE,
              type = c("viewSums","viewMins",
              "viewMaxs", "viewMeans"))

    ## S4 method for signature 'RleList'
    stat_slice(data, ...,
              xlab, ylab, main,
              indName = "sample",
              na.rm = FALSE,
              geom = NULL,
              lower=-Inf, upper=Inf,
              includeLower=TRUE, includeUpper=TRUE,
              rangesOnly = FALSE,
              type = c("viewSums","viewMins",
                       "viewMaxs", "viewMeans"))

### Arguments

`data` | a `data.frame` or `Rle` or `RleList` object.
`...` | arguments passed to aesthetics mapping.
`xlab` | x label.
`ylab` | y label.
`main` | title.
`indName` | when faceted by a `RleList`, name used for labeling faceted factor. Default is 'sample'.
`geom` | geometric types.
`type` | statistical summary method used within bins, shown as bar height or heatmap colors.
`na.rm` | logical value, default `FALSE`, passed to function like `viewMaxs` for statistical summary computation.
`lower` | passed to `slice`.
`upper` | passed to `slice`.
`includeLower` | passed to `slice`.
`includeUpper` | passed to `slice`.
`rangesOnly` | passed to `slice`.

### Value

    ## y scale are different.
