merge_eset: Merge Expression Sets by Row Names

In IOBR: Immune Oncology Biological Research

Merge Expression Sets by Row Names

Description

Merges two or three expression sets (matrices or data frames) by row names (gene symbols), removing duplicates. The function ensures common genes across all input expression sets are retained.

Usage

merge_eset(eset1, eset2, eset3 = NULL)

Arguments

eset1	First expression set (matrix or data frame with row names).
eset2	Second expression set (matrix or data frame with row names).
eset3	Optional third expression set. Default is 'NULL'.

Value

Merged expression set (data frame) with duplicates removed. Row names correspond to gene symbols.

Examples

# Create mock expression sets with common genes
set.seed(123)
common_genes <- c("TP53", "BRCA1", "EGFR", "MYC")
eset1 <- matrix(rnorm(12),
  nrow = 4,
  dimnames = list(common_genes, paste0("S", 1:3))
)
eset2 <- matrix(rnorm(16),
  nrow = 4,
  dimnames = list(common_genes, paste0("S", 4:7))
)
# Merge two expression sets
merged_eset <- merge_eset(eset1, eset2)
print(dim(merged_eset))
