get_trace: Tracing the index over an interpolated planned tour path.

Description

Tracing is used to test if the index value varies smoothly over an interpolated tour path. The index value is calculated for the data d in each projection in the interpolated sequence. Note that all index functions must take the data in 2-d matrix format and return the index value.

Usage

get_trace(d, m, index_list, index_labels)

Value

index values for each interpolation step

Arguments

d

data

m

list of projection matrices for the planned tour

index_list

list of index functions to calculate for each entry

index_labels

labels used in the output

Examples

d <- spiral_data(100, 4)
m <- list(basis_matrix(1,2,4), basis_matrix(3,4,4))
index_list <- list(tourr::holes(), tourr::cmass())
index_labels <- c("holes", "cmass")
trace <- get_trace(d, m, index_list, index_labels)
plot_trace(trace)
