Y-axis scale for strand tracks — scale_y

Provides y-axis labels for strand tracks produced by geom_gene. Now uses discrete scale to match the factor levels created by geom_gene. The default labels are "- strand" and "+ strand" as created by geom_gene.

Usage

scale_y_strand(labels = NULL, ...)

Arguments

labels: Character vector of labels to display. If NULL, uses the factor levels from geom_gene.
...: Additional arguments passed to ggplot2::scale_y_discrete.

Value

A ggplot2 scale object for the y-axis.

Examples

if (FALSE) { # \dontrun{
library(ggplot2)
p <- ggplot(df) + geom_gene(...) + scale_y_strand()
# Or customize labels:
p <- ggplot(df) + geom_gene(...) + scale_y_strand(labels = c("-", "+", "?"))
} # }
