Getting frequencies from a vector with an optional multiplier

Source: R/mapping.R

getting frequencies for a vector with an optional multiplier.

get_freqs(x, multiplier = NULL)

Arguments

x

`vector` categorical variable to summarize.

multiplier

`numeric` vector how many times to repeat certain value, additional weights.

Value

`data.frame` with two columns `input` `Freq`

Note

without multiplier variable it is a basic `table` function wrapped with the `as.data.frame` function. The `table` function is used with the `useNA = "ifany"` argument.

Examples

data("occup", package = "cat2cat")

head(get_freqs(occup$code[occup$year == "2008"]))
#>   input Freq
#> 1  1112   35
#> 2  1123    2
#> 3  1211  202
#> 4  1212   91
#> 5  1221    9
#> 6  1222   18
head(get_freqs(occup$code[occup$year == "2010"]))
#>    input Freq
#> 1 111102    1
#> 2 111103   10
#> 3 111201    3
#> 4 111301   34
#> 5 111405    5
#> 6 112001   13
