Common sequences scatter plot

Creates a scatter plot of just the sequences in common between two samples.

Usage

commonSeqsPlot(sample1, sample2, amino_table, show = "common")

Arguments

sample1

A name of a repertoire_id in a list of data frames generated by the LymphoSeq2 function productiveSeq().

sample2

A name of a repertoire_id in a list of data frames generated by the LymphoSeq function productiveSeq().

amino_table

A tibble of productive amino acid sequences produced by the function productiveSeq() containing the samples to be compared.

show

A character vector specifying whether only the common sequences should be shown or all sequences. Available options are "common" or "all".

Value

Returns a frequency scatter plot of two samples showing only the shared sequences.

Details

The plot is made using the package ggplot2 and can be reformatted using ggplot2 functions. See examples below.
