[Bioc-devel] Use set.seed inside function

[James W. MacDonald]

It appears that you don't actually want random colors, but instead you want the same colors each time. Why not just generate the vector of 'random distinct colors' one time and save the vector of colors?

Subject: [Bioc-devel] Use set.seed inside function

Dear BioC team and developers,

I am using BiocCheck to check my package, it returns a warning:
" Remove set.seed usage in R code"

I am using "set.seed" inside my functions, before calling function distinctColorPalette (randomcoloR package) in order to generate reproducible "random distinct colors". So what would be the best practice to solve this warning? I think 1. use set.seed and don't change anything.
2. use the set.seed function, but include something like below inside the function *gl.seed <- .Random.seed* *on.exit(assign(".Random.seed", gl.seed, envir = .GlobalEnv))* 3. use some other functions for the purpose

Any suggestions will be appreciated. Thanks.
