checkmate namespace imports with
selective imports to avoid new R-devel warnings from upstream
rlang exports (check_string() and
check_data_frame())tf_register() & co implement registration methods
(SRVF, affine, landmark, continuous-criterion) for aligning functions
and analyzing phase variability. Returns a new
tf_registration class with accessors
tf_aligned(), tf_inv_warps(),
tf_template().tf_depth() now implements five functional depth
methods: MBD (default), MHI, FM (Fraiman-Muniz), FSD (Functional Spatial
Depth), and RPD (Regularized Projection Depth). MHI ranks functions from
lowest (0) to highest (1); all other depths are scaled from 0 (most
extreme) to 1 (most central). MBD is now scaled to [0, 1] instead of [0,
0.5].tf_split() / tf_combine() for splitting
functions into sub-domain fragments and re-combining themtf_rgp() gains a "brownian_bridge"

interpolates to a common gridtf_derive() for tfd objects now uses
second-order accurate finite differences, preserving the original domain
