I have several data frames (txt files), with the same number of columns (20), but different number of rows.
For instance,
Dimensions 11770×20
enter image description here
Dimensions 11683×20
enter image description here

I want to merge all the TPM columns to create a data frame/matrix, but my question/issue is that each dataframe/txt file has a different number of rows, hence, I need to properly match the rows using Gene_Id.

I thought about using dplyr or tidyverse but I am uncertain on how to make sure that rows are properly matched, so the matrix/data frame, is not messed up.
