This is a basic implementation of the tidyr package from R.
gather transforms a wide dataset into a long dataset (i.e. reshape long). The command takes a list of variables as argument. This list corresponds to variables to gather.
Use the option
label to save the variable labels as a new variable
spread transforms a long dataset into a wide dataset (i.e. reshape wide). The command takes two variable names as argument. The first variable contains the new variable names. The second variable contains the new variable values.
