df_timebin(df, Δbin; col_y = :erp, fun = mean, grouping = [])

Split or combine DataFrame according to equally spaced time bins.

Arguments:

• df::AbstractTable
  With columns :time and col_y (default :erp), and all columns in grouping;
• Δbin
  Bin size in :time units;
• col_y = :erp
  The column to combine over (with fun);
• fun = mean()
  Function to combine.
• grouping = []
  Vector of symbols or strings, columns to group the data by before aggregation. Values of nothing are ignored.

Return Value: DataFrame.

eeg_matrix_to_dataframe(data::Matrix, label)

Helper function converting a matrix (channel x times) to a tidy DataFrame with columns :estimate, :time and :label.

Return Value: DataFrame.

eeg_topoplot_series(data::DataFrame,
    fig,
    data::DataFrame,

    xlim_topo,
    ylim_topo,
    topoplot_attributes...,
)
eeg_topoplot_series!(fig, data::DataFrame, Δbin; kwargs..)

Plot a series of topoplots. The function automatically takes the combinefun = mean over the :time column of data in Δbin steps.

• fig
  Figure object.
  
• data::DataFrame
  Needs the columns :time and y(=:erp), and label(=:label).
  If data is a matrix, it is automatically cast to a dataframe, time bins are in samples, labels are string.(1:size(data,1)).
• Δbin = :time
  In :time units, specifying the time steps. All other keyword arguments are passed to the EEG_TopoPlot recipe.
  In most cases, the user should specify the electrode positions with positions = pos.
• col, row = :time
  Specify the field to be divided into columns and rows. The default is col=:time to split by the time field and row = nothing.
  Useful to split by a condition, e.g. ...(..., col=:time, row=:condition) would result in multiple (as many as different values in df.condition) rows of topoplot series.
• row_labels, col_labels = false
  Indicate whether there should be labels in the plots in the first column to indicate the row value and in the last row to indicate the time (typically timerange).

Example

df = DataFrame(:erp => repeat(1:63, 100), :time => repeat(1:20, 5 * 63), :label => repeat(1:63, 100)) # simulated data
pos = [(1:63) ./ 63 .* (sin.(range(-2 * pi, 2 * pi, 63))) (1:63) ./ 63 .* cos.(range(-2 * pi, 2 * pi, 63))] .* 0.5 .+ 0.5 # simulated electrode positions
pos = [Point2.(pos[k, 1], pos[k, 2]) for k in 1:size(pos, 1)]
eeg_topoplot_series(df, 5; positions = pos)

Return Value: Tuple{Figure, Vector{Any}}.
