Patients code to text for table

Hi All. Cannot get to read numbers from a matrix and make them into a text to be inserted in a table. The latter to be used in a ranova test. For example.

Injection = [1;1;2;2;3]
Table (1:5,x) = ['Upper_limb', 'Upper_limb','Lower_limb','Lower_limb','Back'];

cheers

Is Table intended to be a table() object? Is x intended to be a column number in the table object?

Are you trying to do something like

Injection = [1;1;2;2;3]
Table = table(Injection);
Table(1:5,2) = {'Upper_limb', 'Upper_limb','Lower_limb','Lower_limb','Back'} .';

"Lets say that somewhere in a 630x38 matrix there is a "1". I need a table with the same dimensions but where (place) there is a "1" it will now say "Upper_limb" (text)..... same location as in the matrix."

Where X is your matrix:

C = {'Upper_limb', 'Lower_limb', 'Back'};
X = [1,2,1,3,1]
C(X)

Thanks Walter, actually more like (probably this is wrong):

for i = 1:5
if Injection (i)  == 1
Table (i) == 'Upper_Limb'
elseif Injection (i)  == 2
Table (i) == 'Lower_Limb'
end

[Walter Roberson]

Injection = [1;1;2;2;3]

limbs = {'Upper_limb', 'Upper_limb','Lower_limb','Lower_limb','Back'} .';

Table = limbs(Injection);

just re-format before calling it

    %lets say 
      Injection = [1;1;2;2;3]

        %Sort into names that you want
        Upper_limb1 = Injection(1);
        Upper_limb2 = Injection(2);
        Lower_limb1 = Injection(3);
        Lower_limb2 = Injection(4);
        Back = Injection(5);

      injTable = table(Upper_limb1, Upper_limb2,Lower_limb1,Lower_limb2,Back)

    %now just call your table as "injTable" when you need it
%--------------------------------------------------------------

    %now lets say its a row of data...
      Injection = [1,1;1,1;2,2;2,2;3,3]

      Injection = transpose(Injection);

        %Sort into names that you want
        Upper_limb1 = Injection(:,1);
        Upper_limb2 = Injection(:,2);
        Lower_limb1 = Injection(:,3);
        Lower_limb2 = Injection(:,4);
        Back = Injection(:,5);

Table = table(Upper_limb1, Upper_limb2,Lower_limb1,Lower_limb2,Back   

    %now just call "Table" for your column table

just saw walters... that works too

Answer 4

[Luis Eduardo Cofré Lizama]

Thanks again, however, I think I am not asking in the right way. The output I need is a column in a table that reads. Also considering I have more than 200 1,2 and 3s to replace, I thought in using a loop.

Column title: Injection site
'Upper_limb';
'Upper_limb';
'Lower_limb';
'Lower_limb';
'Back';

I'll append next to it all the values for all the rest of the variables

[Walter Roberson]

Injection = [1;1;2;2;3]

limbs = {'Upper_limb', 'Upper_limb','Lower_limb','Lower_limb','Back'} .';
Injection_site = limbs(Injection);

Table = table(Injection_site);

Answer 5

[Luis Eduardo Cofré Lizama]

Maybe I am still not expressing well what I need. Lets say that somewhere in a 630x38 matrix there is a "1". I need a table with the same dimensions but where (place) there is a "1" it will now say "Upper_limb" (text)..... same location as in the matrix.

Cheeeeers

I already gave the code for that, such as https://www.mathworks.com/matlabcentral/answers/415580-patients-code-to-text-for-table#comment_601756
