Formatting Vectors using fprintf

How would one print on the command window a 3x1 vector labeled "R" such that the output line matches the format as shown below? Currently I am using a bunch of fprintf functions and manually spacing out the outputs to make it look right, but I want to know if there's a more compact method of outputting and formatting text into command line.

R = [6640.441; 0; 0];
C = compose('%7s[%10.3f km]',["";"R = ";""],R);
fprintf('%s\n','A) Position with respect to the earth in PQW coordinates:',C{:})

A) Position with respect to the earth in PQW coordinates:
       [  6640.441 km]
   R = [     0.000 km]
       [     0.000 km]

Thank you! This works the most compactly.

R = [6640.441; 0; 0];

C = compose('    [ %8.3f km]',R);
C{2}([1 3]) = 'R=';
fprintf('%s\n',C{:});

    [ 6640.441 km]
R = [    0.000 km]
    [    0.000 km]
