Calculate slopes by groups

1	get_slope_by_group(d, group, x, y)

`d`	wide,dataframe containing the
`group`	name of column
`x, y`	names of column in `d` containing the dependent and independent variables

a dataframe with two columns, one containing the group id and one containing the estimated slope for that group

get_slope(), cross_threshold()

sub02 |>
  tidyr::pivot_wider(names_from = contrast, values_from = y) |>
  get_slope_by_group(voxel, low, high)

# create group with intersection of variables
sub02 |>
  tidyr::pivot_wider(names_from = contrast, values_from = y) |>
  get_slope_by_group(c(voxel, sub), low, high)
