R+knitr. Is it possible to form a list of itemize by condition from the list?

Question

R

Greetings!
Through transformations and filtering, I got:

Category                                 n
  <fct>                                <int>
1 Ошибки при вводе данных                121
2 Отсутсвие предварительной обрабоки      17
3 Прочее                                  14
4 Программные ошибки                       1

> str(low_risk)
Classes ‘grouped_df’, ‘tbl_df’, ‘tbl’ and 'data.frame':	4 obs. of  2 variables:
 $ Category : Factor w/ 9 levels "Ошибки при вводе данных ",..: 4 9 7 3
 $ n                  : int  121 17 14 1
 - attr(*, "groups")=Classes ‘tbl_df’, ‘tbl’ and 'data.frame':	4 obs. of  2 variables:
  ..$ Category : Factor w/ 9 levels "Ошибки при вводе данных ",..: 3 4 7 9
  ..$ .rows              :List of 4
  .. ..$ : int 4
  .. ..$ : int 1
  .. ..$ : int 3
  .. ..$ : int 2
  ..- attr(*, ".drop")= logi TRUE

It is necessary in Rnw to form a line of the form:
Data entry errors - 121 (80% of the total), Lack of preprocessing - 17 (14% of the total)

(i.e. 1 row of the 1st column of the dataframe is taken from the table -- 1 row 2nd column of the dataframe,)) and so on. to the end length(low_risk$n) )

That's just how to form and insert data and it doesn't work. It is clear that everything revolves around the for loop, but there is very little experience with R.
