Closed:How to find commonly differentially expressed genes between two conditions

Question

[koushikayaluri]

I have two different data frame with the list of differentially expressed genes. How do I find common genes between those two different data frames? I was thinking of matching the row names and extracting the common row names between the two data frames. But can anyone please guide me on how I can proceed to tackle this problem? Thank you in advance. This is an example dataframes.

df_1                                        df_2
