get_granger_interactions function

Get Granger Causality interactions

get_granger_interactions(
  sv,
  columns,
  cond_column = "",
  sig_level = 0.05,
  lag = 1,
  granger_fn = ms_grangertest2
)

Arguments

• sv: SplicedView object
• columns: vector of column names
• cond_column: name of conditioning column
• sig_level: significance level
• lag: in seconds (rounded to nearest frame)
• granger_fn: function to perform Granger test (defaults to ms_grangertest2)

Returns

GrangerInteraction object

Examples

r <- get_sample_recording()
fv_list <- get_filtered_views(r, "Nose", n = 41, p = 3)
jv_sub <- get_joined_view(fv_list)
l <- list(a = c(0, 300), b = c(300, 600), c = c(600, 900))
splicing_df <- splice_time(l)
sv <- get_spliced_view(jv_sub, splicing_df)
g <- get_granger_interactions(sv, c("Nose_x_Central_Sitar", "Nose_x_Central_Tabla"), lag = 1/25)
print(g)
