Handle lists of fmesher objects — fm

Methods for constructing and manipulating fm_list objects.

Usage

fm_list(x, ..., .class_stub = NULL)

fm_as_list(x, ..., .class_stub = NULL)

# S3 method for fm_list
c(...)

# S3 method for fm_list
[(x, i)

Arguments

x: fm_list object from which to extract element(s)
...: Arguments passed to each individual conversion call.
.class_stub: character; class stub name of class to convert each list element to. If NULL, uses fm_as_fm and auto-detects if the resulting list has consistent class, and then adds that to the class list. If non-null, uses paste0("fm_as_", .class_stub) for conversion, and verifies that the resulting list has elements consistent with that class.
i: indices specifying elements to extract

Value

An fm_list object, potentially with fm_{class_stub}_list

added.

Methods (by generic)

c(fm_list): The ... arguments should be coercible to fm_list objects.
[: Extract sub-list

Functions

fm_list(): Convert each element of a list, or convert a single non-list object and return in a list
fm_as_list(): Convert each element of a list, or convert a single non-list object and return in a list
