Fixes up local mobile phone numbers to a uniform text format.
Arguments
- x
A character vector of numerical strings.
Value
The updated vector, usually the column of a data frame.
Details
This format is specific to that used in a given location - for
now the function is useful only for Nigeria mobile numbers, which come in
the format expressed by the regex pattern "^0[7-9][0-1][0-9]{8}$".
Note
There is an option for producing warnings on any mobile number entries
that may have been removed from the vector, by setting the option
verbose to TRUE.
Examples
fix_mobile("803-123-4567") # Adds leading '0" and removes separators
#> [1] "08031234567"
