Hi,
how can I look for the ISO code for Namibia 'NA' in a list of ISO codes
which looks something like
# A tibble: 10 × 1
location_code
<chr>
1 NC
[...]
10 NZ
but should look like
# A tibble: 10 × 1
location_code
<chr>
1 NA
2 NC
[...]
11 NZ
In other words 'NA' is taken for the missing value NA.
greetings, el
