plotSubstitutions: Barplot visualization of the number of genomic positions...

In wavClusteR: Sensitive and highly resolved identification of RNA-protein interaction sites in PAR-CLIP data

Description

Graphical representation of the total number of genomic positions exhibiting one or more substitutions of a given type. This information is used to estimate the mixing coefficients of the non-parametric mixture model. If the mixture model fit is provided, returns additional diagnostic plots such as the total number of reads exhibiting a given substitution and relative substitution frequency-dependent representations of the total number of genomic positions with substitutions of a given type.

Usage

plotSubstitutions(countTable, highlight = "TC", model)

Arguments

countTable	A GRanges object, corresponding to a count table as returned by the getAllSub function
highlight	A character indicating which substitution should be highlighted in the barplot. A standard PAR-CLIP experiment employing 4-SU treatment induces T to C transitions, encoded as "TC". Default is "TC".
model	A list containing the model as returned by the function fitMixtureModel

Value

called for its effect
