Arguments

dx_obj

An object of class dx

curve_color

Color of ROC curve

fill_color

Color to be filled in under the ROC curve. Use "transparent" if you do not want a color to show.

text_color

Color of text on ROC curve

add_text

(Logical) Include stats on ROC curve?

add_ref_lines

(Logical) Include reference lines on ROC curve?

add_fractions

(Logical) Include fractions on ROC curve?

axis_color

Color of x and y axis

add_ref_circle

(Logical) Include a circle around specificity and sensitivity at the specified threshold?

ref_lines_color

Color for reference lines

circle_ref_color

Color of reference circle

summary_stats

Statistics to include on ROC curve

filename

File name to create on disk using ggplot2::ggsave. If left NA, no file will be created.
