Hello, I hope you are well. I'm starting in R and I have a big question, I hope you can help me.
I have a database that contains a column (column k) with cells containing comma separated values. I need to create a new row for each value in the cell associated with the column that contains it (column k). Then, for each new row, I need to copy all the observations from the source row of the comma-separated values (a - j). And so on for each cell containing comma-separated values, from column k.
