Get list of values to provide to lines
argument of dataMapping
objects.
The lines
are internally used as argument of geom_hline
and geom_abline
from ggplot2
Arguments
- foldDistance
Numeric values Caution: this argument is meant for log scaled plots and since fold distance is a ratio it is expected positive. In particular, line of identity corresponds to a
foldDistance
of1
.
Examples
# Get lines for identity and 2-fold distance
getLinesFromFoldDistance(c(1, 2))
#> [[1]]
#> [1] 1
#>
#> [[2]]
#> [1] 2.0 0.5
#>
# Create dataMapping with lines identity and 2-fold distance
dataMapping <- ObsVsPredDataMapping$new(
x = "predicted",
y = "observed",
lines = getLinesFromFoldDistance(c(1, 2))
)
