prep_velocity

Description

prep_velocity

Usage

prep_velocity(
  tsne_dt,
  tall_var_a,
  tall_var_b,
  id_to_plot = NULL,
  max_plotted = 500,
  delta.min = 0,
  delta.max = Inf,
  angle.min = 0,
  angle.max = 360,
  drop_backgroud = FALSE
)

Arguments

tsne_dt	tidy data.table of tsne results. variables names must include: tx, ty, id, and tall_var
tall_var_a	an item in tsne_dt$tall_var. the origin for calculating angle/distance.
tall_var_b	an item in tsne_dt$tall_var. the destination for calculating angle/distance.
id_to_plot	character. ids in tsne_dt$id. Default of NULL causes all ids to be used.
max_plotted	the maximum number of ids to plot.
delta.min	numeric. ids below this delta marked as background.
delta.max	numeric. ids above this delta marked as background.
angle.min	numeric. ids with angle below this marked as background.
angle.max	numeric. ids with angle above this marked as background.
drop_backgroud	if TRUE, all background velocities are dropped. Default is FALSE.

Value

a tidy data.table of velocity measurements from tall_var_a to tall_var_b

Examples

data("tsne_dt")
vel_dt = prep_velocity(tsne_dt,
    unique(tsne_dt$tall_var)[2], unique(tsne_dt$tall_var)[3])
vel_dt
