- x
data frame as returned `predict.model_list`
- caption
Put model performance in plot caption? TRUE (default) prints
all available metrics, FALSE prints nothing. Can also provide metric name
(e.g. "RMSE"), in which case the caption will include only that metric.
- title
Character: Plot title, default NULL produces no title.
- font_size
Number: Relative size of all font in plot, default = 11
- outcomes
Vector of outcomes if not present in x
- fixed_aspect
Logical: If TRUE (default for regression only), units of
the x- and y-axis will have the same spacing.
- print
Logical, if TRUE (default) the plot is printed on the current
graphics device. The plot is always (silently) returned.
- ...
Parameters specific to plot_regression_predictions or
plot_classification_predictions; listed below. These must be named.
- point_size
Number: Point size, relative to 1
- point_alpha
Number in [0, 1] giving point opacity
- target
Not meant to be set by user. outcome column name
- fill_colors
Length-2 character vector: colors to fill density curves.
Default is c("firebrick", "steelblue"). If named, names must match
unique(x[[target]])
, in any order.
- fill_alpha
Number in [0, 1] giving opacity of fill colors.
- curve_flex
Numeric. Kernal adjustment for density curves. Default is
1. Less than 1 makes curves more flexible, analogous to smaller bins in a
histogram; greater than 1 makes curves more rigid.
- add_labels
If TRUE (default) and a predicted_group column was added to
predictions by specifying risk_groups
or outcome_groups
in
link{predict.model_list}
, labels specifying groups are added to the
plot.
- conf_colors
Length-2 character vector: colors to fill density curves.
Default is c("black", "steelblue").
- text_color
Character: color to write percent correct.
Default is "yellow".
- text_size
Numeric or logical: size of percent correct text. Defaults to
3, a readable size. Greater than 20 classes might need smaller text. Text can be
turned off by setting to FALSE.
- text_angle
Numeric or logical: angle to rotate x axis text. Defaults to
60 degrees. Setting to FALSE will turn text horizontal.
- diag_color
Character: color to highlight main diagonal. These are
correct predictions. Default is "red".
