A function to generate a line plot from tracklike genomic data. This pulls data from the Trace object trace_data slot. Check what numeric and categorical variables are available for plotting using Trace.data.
Usage
bb_plot_trace_data(
trace,
yvar = "coverage",
yvar_label = "Coverage",
facet_var = "group",
color_var = "group",
pal = NULL,
legend_pos = "none",
group_filter = NULL,
group_variable = "group"
)Arguments
- trace
A Trace object
- yvar
The trace_data metadata variable that will become the y axis. Defaults to "coverage". Must be numeric.
- yvar_label
The y-axis label for the coverage track. Defaults to "Coverage".
- facet_var
The trace_data metadata variable describing data facets. Each will be placed as a separate horizontal track with the value printed to the left. Optional but recommended. Defaults to "group".
- color_var
The variable to color groups of traces by. Optional but recommended. Defaults to "group".
- pal
A color palette. Can also be added after the fact.
- legend_pos
Color legend position. Can also be added after the fact. Defaults to "none".
- group_filter
Optional metadatavariable to filter trace data by. When imported from signac/seurat objects, this value defaults to "group", so that is the default here. However if constructed manually, you may wish to apply filtering to another variable. If so, apply it to this parameter.
