Not all of us read LaTeX, so this is my initial guess at what you are
requesting.  The "*" after the '1' is a non-space plotmath separator.

plot(0,0,main=expression(italic(X[""*1])))

If you wanted the tick after the 1, then think of 'minute' as a
constant rather than as a function:

plot(0,0,main=expression(italic(X[1*minute])))

Or:

plot(0,0,main=expression(italic(X[minute*1])))

Greater effort at explanation that does not depend on intuiting your
goal from erroneous code.
