Updating columns of list based on match
Purpose The main purpose is to be able to compute the share of resources used by node i in relation to its neighbors: r_i / sum_j^i{r_j} where r_i are node i resources and sum_j^i{r_j} is the sum of i’s neighbors’ resources. I am open to any R, python or eventually stata solutions, that are able to achieve this task on
How to merge multiple columns of a dataframe using regex？
I have a df which as following Here what I want to do is combine those columns and we have two rules: If a column removes _C{0~9} or _C{0~9}{0~9} or _C{0~9}{0~9}{0~9} is equal to another column, these two columns can be combined. Let’s take number_C1_E1 number_C2_E2 number_C3_E1 as an example, here number_C1_E1 and number_C3_E1 can be combined because they are
