mt_qeffect function

Create quantile-effect plot

Function in beta and currently only for internal purposes.

mt_qeffect(
  data,
  compare,
  use = "measures",
  measure = "MAD",
  direction = "upward",
  n_steps = 100,
  return_data = FALSE,
  ...
)

Arguments

• data: a mousetrap data object created using one of the mt_import functions (see mt_example for details). Alternatively, a trajectory array can be provided directly (in this case use will be ignored).
• compare: either a vector, the label of a variable in , or a mousetrap object.
• use: a character string specifying which trajectory data should be used.
• measure: a character value specifying the variable used to calculate the effect between
• direction: a character value.
• n_steps: an integer.
• return_data: boolean.
• ...: additional arguments passed on to points .

Returns

Nothing, when image is plotted using an external device. Otherwise an object of class mt_object_raw containing in a matrix format the image's pixel information.

Examples

# Plot regular heatmap
#SpiveyEtAl2005 = mt_import_long(SpiveyEtAl2005_raw,'x','y',NULL,'t',
#mt_id_label = c('ptp','trial'))
#heatmap = mt_heatmap_raw(SpiveyEtAl2005,xres = 2000)
#mt_heatmap(heatmap,file = NULL)

# compute measures
#SpiveyEtAl2005 = mt_measures(SpiveyEtAl2005)

# Plot heatmap using velocity
#mt_heatmap(SpiveyEtAl2005)
