Replace columns of tables in obj$data in taxmap() objects. See
dplyr::transmute() for the inspiration for this function and more
information. Calling the function using the obj$transmute_obs(...) style
edits "obj" in place, unlike most R functions. However, calling the function
using the transmute_obs(obj, ...) imitates R's traditional copy-on-modify
semantics, so "obj" would not be changed; instead a changed version would be
returned, like most R functions.
obj$transmute_obs(data, ...) transmute_obs(obj, data, ...)
Arguments
| obj | An object of type |
|---|---|
| data | Dataset name, index, or a logical vector that indicates which dataset in
|
| ... | One or more named columns to add. Newly created columns can be
referenced in the same function call. Any variable name that appears in
|
| target | DEPRECIATED. use "data" instead. |
Value
An object of type taxmap()
