Gene expression line plot — get_expression

Plots normalized expression for selected genes across samples or summarized groups with optional transformations and group faceting.

Usage

get_expression_lineplot(
  x,
  genes,
  sample_group = NULL,
  group_column = NULL,
  value_transform = c("log2", "zscore", "none"),
  summarise_groups = FALSE,
  facet_by_group = FALSE,
  color_palette = "Dark 3"
)

Arguments

x: A VISTA object.
genes: Character vector of gene identifiers to plot.
sample_group: Optional character vector specifying which groups (values taken from group_column) to include.
group_column: Optional column name in sample_info defining the grouping/faceting variable.
value_transform: Transformation applied to expression values; one of "log2", "zscore", or "none".
summarise_groups: Logical; if TRUE, averages replicates per group before plotting.
facet_by_group: Logical; facet the plot by the grouping column when TRUE.
color_palette: Qualitative palette name used for gene colors.
