create_alias_mapping {atable} | R Documentation |
Get Aliases of column names
Description
Column names of data.frame in atable must have syntactically valid colnames,
see is_syntactically_valid_name
.
So no blanks or special characters allowed.
But Reporting in human readable language needs special characters.
These functions here allow atable to handle arbitrary character for pretty printing.
Usage
create_alias_mapping(DD, ...)
Arguments
DD |
A data.frame |
... |
Passed from and to other methods. |
Details
We use attributes
here, to assign alternative names to columns.
Also class labelled
created by Hmisc's label
is supported.
See create_alias_mapping
for the function that does the actual work.
If no aliases are found, then underscores in the column names of DD
will be replaced by blanks.
See Examples in ?atable
.
Value
create_alias_mapping
returns a data.frame with two columns old
and new
and
as many rows as DD
has columns. Column old
contains the original column names of
DD
and column new
their aliases.
