Create a table with interpolated signals of an eeg_lst object.

Source: R/plot_helpers.R

Create a default topographic plot based on the segments of the eeg_lst object.

eeg_interpolate_tbl(.data, ...)

# S3 method for eeg_lst
eeg_interpolate_tbl(
  .data,
  .radius = 1.2,
  .diam_points = 100,
  .method = "MBA",
  ...
)

# S3 method for data.frame
eeg_interpolate_tbl(
  .data,
  .radius = 1.2,
  .x = .x,
  .y = .y,
  .value = .value,
  .label = .key,
  .diam_points = 100,
  .method = "MBA",
  ...
)

Arguments

.data

An eeg_lst object or a long table with amplitudes..

...

Various arguments passed to the interpolation method.

.radius

Indicates the radius of the extrapolation, for standard locations of electrodes, 1 indicates no extrapolation beyond the position of the electrodes, 1.2 is the default

.diam_points

Density of the interpolation (number of points that are interpolated in the diameter of the scalp).

.method

Method of interpolation ("MBA" Multilevel B-splines using the function mba.surf of the package MBA or ("akima" bicubic spline Akima interpolation algorithm using the function interp of the package akima.)..).

.x

Variable storing the x coordinate, generally .x (default).

.y

Variable storing the y coordinate, generally .y (default).

.value

Values used for the interpolation, generally .value (default).

.label

Label of the points that are used for the interpolation, generally .key (default).
