theme_kodom: Clean theme for ggkodom linear and heatmap plots

In ggkodom: Visualize Individual Longitudinal Trajectories

Clean theme for ggkodom linear and heatmap plots

Description

Based on ggplot2::theme_minimal(): vertical x-axis grid lines mark time positions, horizontal y-axis grid lines are suppressed (they would bisect subject lanes and add clutter). Restrained axis text, wide horizontal color-bar legend. Suitable for geom_kodom_line() and geom_kodom_heatmap().

Usage

theme_kodom(base_size = 12, legend_position = "top")

Arguments

base_size	Base font size (default 12).
legend_position	One of "top", "bottom", "left", "right", "none".

Details

The vertical grid lines can be suppressed or restyled via the usual ggplot2 theme() override:

+ theme(panel.grid.major.x = element_blank())

Value

A ggplot2::theme() object.

Examples

library(ggplot2)
df <- data.frame(
  subject_id = rep(1:5, each = 4),
  time = rep(1:4, 5),
  visit_month = rep(1:4, 5),
  value = rep(1:4, 5),
  hba1c = rep(1:4, 5),
  arm = rep(c("Treatment", "Control"), c(12, 8))
)
ggplot(df, aes(x = time, id = subject_id, colour = value)) +
  geom_kodom_line() +
  scale_colour_kodom() +
  theme_kodom()
