Export Overlap Groups to Excel

This function exports the output of extractOverlaps() to an Excel file, creating one sheet per overlap group. Genomic overlaps (GRanges) are converted to data frames before export.

Usage

exportOverlaps(
  grouped,
  output_dir = ".",
  output_file = "overlap_groups",
  with_date = TRUE,
  verbose = TRUE
)

Arguments

grouped

Overlap groups from extractOverlaps().

output_dir

A string specifying the output directory. Defaults to ".".

output_file

A string specifying the base filename (without extension). Defaults to "overlap_groups".

with_date

Logical (default TRUE). Whether to prepend the current date (from today) to the filename.

verbose

Logical. If TRUE, print a message with the saved path. Default TRUE.

Value

Overlap groups are saved to a Excel file on disk. Invisibly returns the full path to the saved file.

Examples

res <- computeOverlaps(list(A = letters[1:3], B = letters[2:4]))
grouped <- extractOverlaps(res)
exportOverlaps(grouped, output_dir = tempdir(), output_file = "overlap_groups.xlsx")
#>  > Overlap groups saved in /tmp/RtmpM1wcpl/20250926_overlap_groups.xlsx.xlsx
