## S3 method for class 'fm_bbox'
c(..., .join = FALSE)

Arguments

...

Passed on to sub-methods

x

fm_bbox object from which to extract element(s)

i

indices specifying elements to extract

.join

logical; if TRUE, concatenate the bounding boxes into a single multi-dimensional bounding box. Default is FALSE.

Value

For c.fm_bbox(), a fm_bbox_list object if join = FALSE (the default) or an fm_bbox object if join = TRUE.

Methods (by class)

• fm_bbox(list): Construct a bounding box from precomputed interval information, stored as a list of 2-vector ranges, list(xlim, ylim, ...).

Methods (by generic)

• [: Extract sub-list

• c(fm_bbox): The ... arguments should be fm_bbox objects, or coercible with fm_as_bbox(list(...)).

Examples

fm_bbox(matrix(1:6, 3, 2))
m <- c(A = fm_bbox(cbind(1, 2)), B = fm_bbox(cbind(3, 4)))
str(m)
str(m[2])
