trim: trim and resize methods: trim_left, trim_right, resize_left,...

In wokai/spliceSites: A bioconductor package for exploration of alignment gap positions from RNA-seq data

Description

The trim and resize functions change number of nucleotides contained in align-gap features (exonic). Trim functions cut feature sizes down to maxlen. Resize functions reset all sizes to a fixed value. The functions operate directly on the passed objects. There is no return value.

Usage

trim_left(x,maxlen)

Arguments

x	gapSites. Object from which the lJunc values are calculated.
maxlen	Numeric. Maximum number of nucleotides on feature (exon) side of boundary.

Value

None.
