Dear Experienced R users, I have a looks-like simple but complicated problem urgently needed to be solved. Below is the detail:
I have two dataframes, df1, df2. df1 contains two column and many thousands rows: column 1 is a "gene_name", column 2 is "value". df2 contains only one column which is "gene_name" with couple hundred rows. I want to change "value" of df2 for those "gene_name" also appear in df2 "gene_name". How to do that? Millions thanks.
