I'm new with R, so not sure how to program with R I have 2 data frames, the first one (tst_dp) I have assigned numeric values depending on the string value of the Ac1CodSinDuplicados column

   Ac1CodSinDuplicados valor
                  ESP     1
               FRAOPP     2
                  BUS     3
                  USA     4
                  DEU     5
               ESPGOV     6
                  GOV     7
               ESPCVL     8

...

And I have a second data frame

> ds2
   Actor1Code Actor2Code
     ESP     BUS

I want to search in the first data frame and assign the numeric value in the second,for example, for every ESP, assign value 1, etc..

The final result will be a dataframe of only numeric values Actor1Code Actor2Code 1 3
