Scatter plots for very dens datasets — gg

gg_dens Scatter plots with 2D density as color and alpha scale to beter visualise very dens data.

Usage

gg_dens(
  IC,
  x,
  y,
  xlab = ggplot2::waiver(),
  ylab = ggplot2::waiver(),
  ttl = "",
  gr = NULL,
  downsample = 1,
  x_lim = NULL,
  y_lim = NULL,
  unit = "dim",
  sds = 22,
  geom = "point",
  facet_sc = "fixed",
  labels = "standard",
  flag = NULL,
  save = FALSE
)

Arguments

IC: Ion count data.
x: Variable for the x axis.
y: Variable for the y axis.
xlab: Character string or expression for x axis label.
ylab: Character string or expression for x axis label.
ttl: Character string or expression for plot title.
gr: A grouping variable.
downsample: A numeric supplying the fraction for down-sampling of the original data frame.
x_lim: Numeric range for x axis (default = NULL).
y_lim: Numeric range for y axis (default = NULL).
unit: A character string for the units of the grouping variable. The string "um" is used for the grid cell size comparison plots. The string "dim" is used for all other plots, and defaults to the grouping variable name.
sds: Numeric settings the seeds for down-sampling via `set.seed()`.
geom: A character string for the geometry mapped on the aesthetics. Options are "point" for normal scatter plots, and "dens2d" for density contour lines.
facet_sc: The scales parameter of `ggplot2::facet_grid`
labels: Either "scientific" or "standard".
flag: A variable representing a flag for outliers.
save: Boolean whether to save the plot as an png.
