Hi @ninou,

First, please consider to use a reproducible example (reprex) in this question, that way it can be easy to help you: FAQ: What's a reproducible example (`reprex`) and how do I do one?

Besides that, reshape() is a function from base R. Have you tried to use the gather() and spread() functions from the tidyr package (which is part of the tidyverse)?
