compact.gene.list: Make a compact version of gene annotation
In humarray: Simplify Analysis and Annotation of Human Microarray Datasets

Description Usage Arguments Value Examples

When adding gene annotation to genomic ranges, sometimes there are many genes associated with a single feature, so that compiling a table becomes awkward, if some rows contain hundreds of genes. This function takes a character vector of gene lists delimited by some separator and provides a compact representation of the gene labels

1	compact.gene.list(x, n = 3, sep = ";", others = FALSE)

`x`	is a character vector of gene label listings, where multiple hits are delimited by 'sep'
`n`	number of genes to list before abbreviating
`sep`	character, separator used to delimit genes in elements of x
`others`	logical, TRUE to abbreviate with '+ # others' or FALSE to append just the number of genes not listed.

a character vector with the form: gene-1, gene-2, ..., gene-n, + length(gene-n) - n [others]
