compositional analysis?

Hi,

I have data on the bacterial compositions of skin swabs of 900 patients. I want to know if there is a difference in bacterial composition between males and females. I have stumbled upon compositional analysis but I don't know if it is the right way to do it and I don't know how to do it. Can any of you help me?

I have data that look like this:

female data set

sex sample count percent

1 CNS 511 63%

1 Gram-negative rods 63 8%

1 Gram-positive rods 63 8%

1 Micrococcus 127 16%

1 Other Gram-postive cocci 37 5%

1 Staphylococci 8 1%

male data set

2 CNS 447 68%

2 Gram-negative rods 33 5%

2 Gram-positive rods 54 8%

2 Micrococcus 98 15%

2 Other Gram-positive cocci 18 3%

2 Staphylococci 5 1%

Hi,

just to maybe get things going: Can you specify what your desired outcome would be?

I have no idea of compositional analysis. My data-management-based approach would be to merge the datasets and just compare the male vs, female values with simple if statements or something.

Let me know if you need a code example for that should you need one.

Best,

Nico
