Individual Patient Plot Over Time
For illustration purposes, we will subset the adlb dataset for safety population in treatment arm A and a specific lab parameter (ALT).
Output
The user can select different plotting_choices depending on their preference. To demonstrate, separate plots are produced with a maximum of 3 observations each.
Here, patients’ individual baseline values will be shown for reference. Note that users can provide their own custom theme to the function via the ggtheme argument.
Code
plots <- g_ipp(
df = adlb_f,
xvar = "AVISIT",
yvar = "AVAL",
xlab = "Visit",
ylab = "SGOT/ALT (U/L)",
id_var = "Patient_ID",
title = "Individual Patient Plots",
subtitle = "Treatment Arm A",
add_baseline_hline = TRUE,
yvar_baseline = "BASE",
ggtheme = theme_minimal(),
plotting_choices = "split_by_max_obs",
max_obs_per_plot = 3
