plotBases: Plot Bases by Position
In vsbuffalo/qrqc: Quick Read Quality Control

Description Usage Arguments Author(s) See Also Examples

plotBases plots the frequency or proportion of bases by position in the read.

plotBases uses the Sanger base color scheme: blue is Cytosine, green is Adenine, black is Guanine, red is Thymine, and purple in N (any base). Other IUPAC nucleotides are colored using RColorBrewer.

1	plotBases(obj, type="freq", bases=NULL, legend=TRUE)

`obj`	an S4 object of class that inherits from `SequenceSummary` (either `FASTASummary` or `FASTQSummary`) from `readSeqFile`.
`type`	a character string that is either "freq" or "prop" indicating whether to plot frequencies or proportions on the y-axis.
`bases`	a vector of characters indicating which bases to include. The default value `NULL` indicates to plot _all_ bases.
`legend`	a logical value indicating whether to include a legend on the top right.
