R script for Gene ID Mapping?

Question

[shrgur]

Hey everyone,

I have two files;

I want to create a new file with two columns ie. reaction ID and its corresponding Gene ID.

Is there a command similar to grep in R? if so, how can I use it in this scenario?

I would really appreciate any input/suggestions regarding this. Thank you!!

Please search StackOverflow or any forum online for the merge or dplyr::join functions. R does have a grep but it won't be of much use here.

You'll need to use tidyr::separate_rows on the second column of the first dataset, then dplyr::inner_join on the datasets to get your results.
