To add bands from factor to factor
geom_pcp_band( mapping = NULL, data = NULL, stat = "pcpband", position = "identity", ..., freespace = 0.1, boxwidth = 0, rugwidth = 0, interwidth = 1, resort = NULL, reverse = FALSE, merge = FALSE, na.rm = FALSE, show.legend = NA, inherit.aes = TRUE )
Arguments
| mapping | Set of aesthetic mappings created by [aes()] or [aes_()]. If specified and `inherit.aes = TRUE` (the default), it is combined with the default mapping at the top level of the plot. You must supply `mapping` if there is no plot mapping. |
|---|---|
| data | The data to be displayed in this layer. There are three options: If `NULL`, the default, the data is inherited from the plot data as specified in the call to [ggplot()]. A `data.frame`, or other object, will override the plot data. All objects will be fortified to produce a data frame. See [fortify()] for which variables will be created. A `function` will be called with a single argument, the plot data. The return value must be a `data.frame`, and will be used as the layer data. |
| stat | The statistical transformation to use on the data for this layer, as a string. |
| position | Position adjustment, either as a string, or the result of a call to a position adjustment function. |
| ... | Other arguments passed on to [layer()]. These are often aesthetics, used to set an aesthetic to a fixed value, like `colour = "red"` or `size = 3`. They may also be parameters to the paired geom/stat. #' |
| freespace | A number in 0 to 1 (excluded). The total gap space among levels within each factor variable |
| boxwidth | A number or a numeric vector (length equal to the number of factor variables) for the widths of the boxes for each factor variable |
| rugwidth | A number or a numeric vector (length equal to the number of numeric variables) for the widths of the rugs for numeric variable |
| interwidth | A number or a numeric vector (length equal to the number of variables minus 1) for the width for the lines between every neighboring variables, either a scalar or a vector. |
| resort | A integer or a integer vector to indicate the positions of vertical axes inside (can't be the boundary of) a sequence of factors. To break three or more factors into sub factor blocks, and conduct resort at the axes. Makes the plot clearer for adjacent factor variables. |
| reverse | reverse the plot, useful especially when you want to reverse the structure in factor blocks, i.e. to become more ordered from right to left |
| merge | To merge the bands or not |
| na.rm | If `FALSE`, the default, missing values are removed with a warning. If `TRUE`, missing values are silently removed. |
| show.legend | logical. Should this layer be included in the legends? `NA`, the default, includes if any aesthetics are mapped. `FALSE` never includes, and `TRUE` always includes. It can also be a named logical vector to finely select the aesthetics to display. |
| inherit.aes | If `FALSE`, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. [borders()]. |
Examples
library(ggplot2) library(dplyr) data(mtcars) mtcars %>% mutate(cyl = factor(cyl), vs = factor(vs), am = factor(am), gear = factor(gear)) %>% ggplot(aes(vars = vars(cyl, vs:gear))) + geom_pcp(aes(color = vs), boxwidth = 0.2, resort = 2:3) + geom_pcp_box(boxwidth = 0.2) + geom_pcp_band(boxwidth = 0.2, resort = 2:3) + geom_pcp_text(boxwidth = 0.2)
