Look over proposal?

[sckott]

@evaristor I'm submitting a proposal to the R Consortium https://www.r-consortium.org/projects/call-for-proposals to fund work on mutant. Would you have time to look over the proposal?

You can see it at https://sckott.github.io/mutant-proposal/ and pdf here https://sckott.github.io/mutant-proposal/index.pdf

You can open an issue or send a PR, whatever you like

I'll gladly look over the proposal within the next few days.

[sckott]

thanks!

The proposal looks great! I'll leave my comments here if that is OK with you.

In lines 46-53:

Create two mutants:

less_than_ten <- function(x) {
  z <- x - 5 # changed + to -
  z < 7 # 10 changed to 7
}

I would separete the mutants in two blocks of code:

Create two mutants. The first mutant changes an operator:

less_than_ten <- function(x) {
  z <- x - 5 # changed + to -
  z < 10
}

The second mutant changes a constant:

less_than_ten <- function(x) {
  z <- x + 5
  z < 7 # 10 changed to 7
}

Even though this is true,

Mutation testing in the R community will not be used as widely as unit testing - not every one that uses unit testing will use mutation testing,

I wouldn't put such an emphasis on it. Maybe you could just start the paragraph with the second sentence. Something like this:

Members of the R community that will find mutation testing most useful will likely be: (...)

Thanks very much! This is very helpful

In line 24,

Mutant should be easily extended to the other two testing packages.

consider using lowercase:

mutant should be easily extended to the other two testing packages.

Sometimes you use plural (We'll) and some time you use singular (I'll)

We’ll address the (...). I’ll leverage the (...)

Probably the plural form sounds better

That's all my feedback. Good luck!
