Alternative names for miss_var_pct and friends (AKA naming things is hard)

[njtierney]

At the moment there are four functions that calculate the percent or proportion of variables/cases that have missings. The names are:

• naniar::miss_var_pct(airquality)
• naniar::miss_var_prop(airquality)
• naniar::miss_case_pct(airquality)
• naniar::miss_case_prop(airquality)

However, in order to make them consistent with n_miss and prop_miss, I think that it might be worth changing the names:

• naniar::miss_var_pct(airquality)
• naniar::pct_var_miss(airquality)
• naniar::pct_miss_var(airquality)

• naniar::miss_var_prop(airquality)
• naniar::prop_var_miss(airquality)
• naniar::prop_miss_var(airquality)

• naniar::miss_case_pct(airquality)
• naniar::pct_case_miss(airquality)
• naniar::pct_miss_case(airquality)

• naniar::miss_case_prop(airquality)
• naniar::prop_case_miss(airquality)
• naniar::prop_miss_case(airquality)

I am going to suggest the following changes:

current_names	new_names
miss_case_pct	pct_miss_case
miss_case_prop	prop_miss_case
miss_var_pct	pct_miss_var
miss_var_prop	prop_miss_var
complete_case_pct	pct_complete_case
complete_case_prop	prop_complete_case
complete_var_pct	pct_complete_var
complete_var_prop	prop_complete_var

and I will soft-deprecate the old names.
