This is what I wanted to do

so I am trying to merge these dataframe, therefore as a table with name / proportion / degree_length

but the condition is that I will only use the rows which they share same name.

How should I code this? Thank you

  • Your use of images to display what you are hoping for is very clear and demonstrative, so I think my previous comment will be enough. If not, though, however clear your images are, they are just images, and you may find a negative reaction by many (for good reasons, https://meta.stackoverflow.com/a/285557). A better strategy is to include a sample of both frames and the expected output, all via an unambiguous data sample such as the output from `dput`; see https://stackoverflow.com/q/5963269, [mcve], and https://stackoverflow.com/tags/r/info. Thanks! – r2evans Feb 24 '21 at 05:53
