Some information regarding the ~ symbol...

Some information regarding the ~ symbol...

Some points:

1. The symbol ~ is called tilde so searching with the word is useful. 
2. It's use in v~Vmax*S/(Km+S) is to create the non-linear formula. 
3. It's special R syntax rather than general bioinformatics syntax. 
4. It's specific meaning in this context is to create a formula object in R which can be used later. 
5. The ~ symbol (tilde) separates one side of the formula from the other.
6. The symbol means that R doesn't try to evaluate the formula but creates an object - sometimes a "formula" object

By way of an example, here is some R code:

my_formula <- y ~ bot+(top-bot)/(1+( x / LD50)^slope)

class(my_formula)

The tilda means that the equation won't be run but just the object created. 

The object in this case is my_formula and the class of the object is "formula". The tilda sets y on the left hand side and x, bot, top, LD50 and slope on the right hand side. 

That's enough for a start but questions are welcome. 

Some resources:

• This repeats much of what I have said and is the source of some of my knowledge:    https://stackoverflow.com/questions/14976331/use-of-tilde-in-r-programming-language
• This is a more detailed comment on what the tilde does in a variety of situations. It's quite detailed R written by one of the senior developers in the field. https://cran.r-project.org/web/packages/lazyeval/vignettes/lazyeval.html
  

END of info for now...
