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.

Value

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)
