radiatR keeps a tidyverse-shaped surface: data flows as plain tibbles addressed by column name, and rich objects are reserved for structure a flat table cannot hold safely.
Tracks — trajectories with coordinate geometry, a
per-trajectory reference frame, and transform history (invariants a bare
tibble cannot enforce).circ_display() — an orientation convention (zero
direction, rotation).circ_regression() — a fitted model (like
lm).Plain tibbles are addressed by a column-name argument
(angle_col = "heading"). The circular
package’s circular objects are an internal implementation
detail — built inside functions, never in a public signature or
return.
headings_frame: a dplyr-durable tibble subclassheadings_frame is a tibble subclass that carries the
display convention durably through dplyr verbs (via the
dplyr_reconstruct contract), so a
mutate()/filter() never silently drops the
orientation. Read its metadata with the hf_* accessors. A
plain data frame with a heading column is always an acceptable
substitute — the class is an enhancement, never a requirement:
data(cpunctatus)
hd <- derive_headings(cpunctatus, rule = "distal")
hd2 <- dplyr::filter(hd, is.finite(heading)) # class + display preserved
class(hd2)
#> [1] "headings_frame" "tbl_df" "tbl" "data.frame"
hf_display(hd2)
#> $zero
#> [1] 1.570796
#>
#> $clockwise
#> [1] TRUE
#>
#> $units
#> [1] "degrees"
#>
#> attr(,"class")
#> [1] "circ_display"These binaries (installable software) and packages are in development.
