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)
Value
An fm_list object, potentially with fm_{class_stub}_list
added.
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
Methods (by generic)
c(fm_list): The ... arguments should be coercible to fm_list
objects.
