Rattle

This is very basic. Have you gone through any R tutorials? There are
many good ones on the web. e.g., see here:
https://www.rstudio.com/online-learning/#R

In any case, you should not expect this list to teach you basic R. You
*should* expect it to help you learn and improve your own efforts. I
realize that there is a gray area where these things may overlap.

Also see inline below.

Dear all,

I`ve got to calculate the ratio of methanogens to bacteria, but I

wouldn`t

like to divide the total copy numbers of methanogens ( on average 10^8)

by

bacteria (10^10) because they have different exponents and bases. So, my
idea is to standardize both microorganisms counts to 10^3.

Why can't you use scientific notation? What form are your data in?

e.g.

a <- 6.2E8; b <- 5.4E10
a/b

[1] 0.01148148

Hypothetical example of what I`d like to do:

Total Methanogens: 28 x 10^3
Total bacteria: 710 x 10^3


Total: 710 + 28= 738 x 10^3

Met/bac Ratio : (28/738)*100 = 3.79%

How could I perform this calculation in R?

Thanks,
