[R] Assigning entries to category

I have the following problem:
I have a large dataframe where each row is specified by two numerical value (one 1:25 and the other one large specific number (e.g. 203043)). I have a list of 60 categories which are also assigned to one of the first numerical value (1:25) but have a range for the second numerical value (e.g. 200020 - 208040) in two different columns.

I want now to assign a category to each row in a new variable by testing for accordance to the first numerical value and overlap of the second numerical value with the range.

For example:
entry1 has numerical value 1 = 15 and numerical value 2 = 200050. This would be assigned to category3, which has a numerical value 1 = 15 and a range for numerical value 2 = 200000 - 201000.

It would be great if any one could help me out with this.
