I have a time table and want to remove a column that marks true or false, so it can be retimed (retime does not work if there are characters), then add it back once retime is finished.

Suppose the entry at 6.8 has the flag false, and the entry at 7.2 has the flag true, then when retime tries to create the entry for 7.0 should the flag be set to false or to true or to round(interp1([6.8 7.2], [0 1], 7.0)) ?

Selecting only variables of a certain type is easy if you index into the timetable using a vartype. Adding the variables that you didn't retime back into the timetable is likely to be trickier.
dt = datetime('now')+minutes([0; 5]);
T = timetable(dt, [0; 5], [true; false])
V = vartype('double');
R = retime(T(:, V), 'minutely', 'linear')
What should be the values for Var2 in each row of R? If it should be a logical variable, where should the transition from true to false take place? If it should be a double variable, why not just cast it to double in T using double before calling retime?
