How do I take a "for loop" answer and put it to an "if" statement command?

TNY =[31, 26, 30, 33, 33, 39, 41, 41, 34, 33, 45, 42, 36, 39, 37, 45,43, 36, 41, 37, 32, 32, 35, 42, 38, 33, 40, 37, 36, 51, 50];

TAN =[37, 24, 28, 25, 21, 28, 46, 37, 36, 20, 24, 31, 34, 40, 43, 36, 34, 41, 42, 35, 38, 36, 35, 33, 42, 42, 37, 26, 20, 25, 31];

X = mean(TNY)< TNY;
Y= mean(TAN)< TAN;

sum(X);
sum(Y);

R = zeros(size(TNY));

for i = 1:length(TAN)

      R = R + (TNY==TAN(1,i));

end

R

%%R= 2 1 0 1 1 0 1 1......... 

% I want to add 1 to any number that is not 0.

% I've tried 

if R>0

R+1

end

That doesn't work.

Help!

mask = R ~= 0;
R(mask) = R(mask) + 1;

Thank you!

Could I have use the "if" statement on this at all?

[Walter Roberson]

for K = 1 : length(R)
  if R(K) > 0; R(K) = R(K) + 1; end
end

Thanks again!
