Dear R forum I have two datafarmes with category and cat_val forming one dataframe and cust and cust_category forming another dataframe.
category = c("C", "D", "B", "A") cat_val = c(0.10, 0.25, 0.40, 0.54) cust = c("cust_1", "cust_2", "cust_3", "cust_4", "cust_5", "cust_6", "cust_7", "cust_8", "cust_9", "cust_10") cust_category = c("C", "A", "A", "A", "A", "C", "D", "B", "B", "D") Thus, I have > category [1] "C" "D" "B" "A" > cat_val [1] 0.10 0.25 0.40 0.54 > cust [1] "cust_1" "cust_2" "cust_3" "cust_4" "cust_5" [6] "cust_6" "cust_7" "cust_8" "cust_9" "cust_10" > cust_category [1] "C" "A" "A" "A" "A" "C" "D" "B" "B" "D" My problem is to match 'cust_category' with 'category' and accordingly selct the value assigned to this category value. In other words, 1st element of cust_category is "C", so it should select the value 0.10, the second element is "A", so it should assign value 0.54 against this. So effectively I should get cust cust_category cat_val cust_1 C 0.10 cust_2 A 0.54 cust_3 A 0.54 ............................................ cust_10 D 0.25 Kindly guide Regards Vincy [[alternative HTML version deleted]]
