rPobably a simple question but I can't find the correct instruction to do it easily.
I have 2 dataframes with the following structure.
Dataframe 1Name1 Name2 Col1 Col2 Col3 Col4aaa bbb 1 3 5 7ccc ddd 9 8 6 4eee fff 2 10 11 12ggg hhh 13 15 17 19aaa jjj 25 35 23 41...Dataframe 2Name ColA ColBaaa 100 200ggg 300 400eee 500 600ccc 700 800...I need to add 2 columns to Dataframe 1 that contain the values in ColA and ColB in Dataframe 2 where Name1 in dataframe1 is equal to name in dataframe2.
To obtain the following:
Dataframe 1Name1 Name2 Col1 Col2 Col3 Col4 ColA ColBaaa bbb 1 3 5 7 100 200ccc ddd 9 8 6 4 700 800eee fff 2 10 11 12 500 600ggg hhh 13 15 17 19 300 400aaa bbb 25 35 23 41 100 200...Note that Dataframe1 can have several times aaa, bbb, ccc but dataframe2 have onlu one time this value
