Description Usage Arguments Value See Also Examples
Finds the projection index for a matrix of points x
, when
projected onto a curve s
. The curve need not be of the same
length as the number of points.
1 | project_to_curve(x, s, stretch = 2)
|
x |
a matrix of data points. |
s |
a parametrized curve, represented by a polygon. |
stretch |
A stretch factor for the endpoints of the curve, allowing the curve to grow to avoid bunching at the end. Must be a numeric value between 0 and 2. |
A structure is returned which represents a fitted curve. It has components
s |
The fitted points on the curve corresponding to each point |
ord |
the order of the fitted points |
lambda |
The projection index for each point |
dist |
The total squared distance from the curve |
dist_ind |
The squared distances from the curve to each of the respective points |
