LS-means by visit

Per-visit ANCOVA of value_col on treatment, adjusted for baseline (BASE) when it is available. The baseline visit (lowest AVISITN) is then excluded. This is a per-visit model, not an MMRM.

Usage

fig_lsmeans(
  df,
  ctx = fig_ctx(),
  value_col = "AVAL",
  ci = 0.95,
  point_labels = FALSE,
  show_n = FALSE,
  base_size = NULL,
  config = NULL
)

Arguments

df

Analysis data (BDS).

ctx

A fig_ctx() list.

value_col

"AVAL" or "CHG".

ci

Confidence level.

point_labels

Print the mean above each point?

show_n

Print per-visit N under the panel?

base_size

Font size; NULL uses the configuration.

config

A tlf_config(); NULL resolves through tlf_get_config().

Value

A ggplot.
