segMerge


    A <code>data.frame</code> of segments, with at least &quot;chrom&quot;, &quot;start&quot; and &quot;end&quot; columns. Standard behavior (default <code>fun</code> value) assumes &quot;start&quot; and &quot;end&quot; to be at least <code>numeric</code>, preferably <code>integer</code>.


segTable


    Character vector, <code>segTable</code> columns that must all be identical for the consecutive rows to be merged. For convenience, &quot;chrom&quot; is forced in and &quot;start&quot; / &quot;end&quot; are forced out.



    A <code>list</code> of <code>function</code>s, defining how to merge values when merging rows. It should contain an unamed element for the default function, and named elements to deal with specific columns.


Given a set of segments defined by &quot;chrom&quot;, &quot;start&quot;, &quot;end&quot; and various data, it merges consecutive rows (sorted by &quot;chrom&quot; then &quot;start&quot;) that share same data. As an example, it is useful to merge consecutive regions of the genome sharing same copy numbers after modelization, or filling small gaps.

Classes and methods to efficiently handle (slice, annotate, draw ...) genomic features (such as genes or transcripts), and an interactive interface to browse them.
