Plot pairwise correlations between samples — get_pairwise_corr

Uses GGally::ggpairs on normalized expression to display correlations among samples from selected groups/genes.

Usage

get_pairwise_corr_plot(
  x,
  sample_group = NULL,
  group_column = NULL,
  genes = NULL,
  sample_order = c("input", "group"),
  value_transform = c("log2", "none"),
  title = "Pairwise Sample Correlations"
)

Arguments

x: A VISTA object.
sample_group: Optional character vector of groups (from the column specified by group_column) used to subset samples.
group_column: Optional column name in sample_info defining the grouping used for filtering.
genes: Optional character vector of gene IDs to include; defaults to all genes.
sample_order: Ordering for selected samples: "input" keeps the current order, while "group" sorts by group_column.
value_transform: Value transformation: "log2" (default) or "none".
title: Plot title.

Value

An object returned by this function.

Examples

v <- example_vista()
p <- get_pairwise_corr_plot(v)
print(p)
