Description Usage Arguments Details Value Examples
This function is similar to purrr::map()
except that instead of stopping at
the first error it captures them and continues. If there are any errors it
collects them together and displays them at the end. You have the option to
specify a prefix to the error message using the msg_prefix
argument.

x |
(vector or list) The vector or list to map the function to. |
f |
(function) The function to map to the elements of |
... |
(optional) Extra arguments to supply to f. |
msg_prefix |
(string, optional) A message to prefix any resulting error message. |
warn_level |
(integer, optional) The level of any warnings about errors encountered. If 0 then no warnings are shown. Default: 2. |
error_level |
(integer, optional) The level of any resulting errors. Default: 1. |
on_error |
(string) The kind of message to produce if there is an error. Either "info", "warn", or "error". Default: "error". |
simplify |
(boolean, optional) Whether to try to simplify the result of the mapping into an atomic vector. Default: FALSE. |
use_names |
(boolean, optional) Whether to use 'x' as names in the resulting list. 'x' must be a character vector for this to work. Default: TRUE. |
If the mapped function is a long running process try_map()
can output a
warning at the time an error occurs, but specifying the warn_level
argument
to be greater than 0 (see warn()
for more details about message levels.
Similarly error_level
argument specifies the level of any reported error,
as detailed in error()
.
If you do not want the function to stop with an error, you can instead return
a warning or info message using the on_error
argument.
Finally, simplify
and use_names
allow the user to specify whether to
simplify the output to an atomic vector, if possible, and whether to use the
vector input x
as names to the resulting list.
If simplify = FALSE
a list is returned. Otherwise, the function
attempts to simplify the result to an atomic vector or array.
