Description Usage Arguments Value See Also Examples

Plots calibration data from generateCalibrationData.

1 2	plotCalibration(obj, smooth = FALSE, reference = TRUE, rag = TRUE, facet.wrap.nrow = NULL, facet.wrap.ncol = NULL)

`obj`	[`CalibrationData`] Result of `generateCalibrationData`.
`smooth`	[`logical(1)`] Whether to use a loess smoother. Default is `FALSE`.
`reference`	[`logical(1)`] Whether to plot a reference line showing perfect calibration. Default is `TRUE`.
`rag`	[`logical(1)`] Whether to include a rag plot which shows a rug plot on the top which pertains to positive cases and on the bottom which pertains to negative cases. Default is `TRUE`.
`facet.wrap.nrow, facet.wrap.ncol`	[`integer()`] Number of rows and columns for facetting. Default for both is `NULL`. In this case ggplot's `facet_wrap` will choose the layout itself.
