rduckhts_bigwig: Create a BigWig Signal Table

In Rduckhts: 'DuckDB' High Throughput Sequencing File Formats Reader Extension

Create a BigWig Signal Table

Description

Materializes stored zero-based, half-open BigWig intervals through the DuckHTS extension. Region filters use htslib's one-based inclusive syntax; a character vector is combined into one multi-region request and overlapping requests emit each stored interval once.

Usage

rduckhts_bigwig(
  con,
  table_name,
  path,
  region = NULL,
  blocks_per_iteration = 64L,
  overwrite = FALSE
)

Arguments

con	A DuckDB connection with DuckHTS loaded.
table_name	Name for the created table, or NULL to create the bigwig_data view.
path	Local path or URL to a BigWig file.
region	Optional character vector of genomic regions such as c("chr1:1000-2000", "chr2:1-500"). A single comma-separated string is also accepted.
blocks_per_iteration	Positive integer number of indexed BigWig data blocks decoded per iterator batch.
overwrite	Logical. If TRUE, replace an existing table.

Value

Invisibly returns TRUE.
