Help needed wtih these codes!

[AnnieRuser]

I can't make this function right
proportion <- function(v,i,j) for(v in i:j){proportion<-return(proportion for(v in i:j)}
I'm trying to make function proportion, wich would return from v values between i:j

Thank you, hadn't noticed that!

For part one i've tried to make these codes, but have i done it too complicated or where i've gone wrong?

proportion <-funktion(v=1,i=0,j=1)[values <-runif(v=V,min=i, max=j)int_values <-round(values),return(int_values)]

proportion= random_integers <-funktion(v,i,j)[values <-runif(v=v,min=i, max=j)int_values <-round(values),return(int_values)]

@AnnieRuser

funktion

This seems like a german spelling, if we assume that you have a localised version of R, this may work, otherwise not. However, its a mistake to use square brackets to enclose the function body, where curly braces are required.
Here is a good intro document for you to review

Iäm unsure how to make this on work: how to get it return values from v between i:j
proportion <- function(v) for(v in i:j){proportion<-return(v, i;j)

[nirgrahamuk]

@AnnieRuser

proportion <- function(v) for(v in i:j){proportion<-return(proportion)}

your function doesnt take v , i and j, it only takes v. .
...and it does nothing with it...proportion <- return(proportion) doesnt relate to v in anyway, its sort of a strange function that returns itself.

[AnnieRuser]

Oh yes, that's it. Now i have to manage make it return values between i and j.

I progressed a bit with sekond part:
proportion <- function(100000) rbinom(n=100000, size=64, prob=1/2)

[nirgrahamuk]

do you have questions about that ?

[AnnieRuser]

Yes, i tried to make my funtion based on it.

proportion <- function(v) for(v in i:j){proportion<-return(proportion)}

Thanks to you i see now that it doesen't return anything. Still can't make it work
proportion <- function(v, i, j) {proportion<-return(proportion for(v in i:j)}

[AnnieRuser]

Does this look better?
proportion <- function(v) {proportion (rep(i:j))<-return(v, i:j)}

[nirgrahamuk]

ok, lets step back from your attempt at function making and see if we can straightforwardly answer some questions relating to the requirements. I expect the first one will be easy , and the second one might require more thought.

1 ) What are the desired parameters for your function 'proportion' ? list them.
2) in R how would one check whether numbers are between other numbers ?
what would you type on the console to check that 4 was between 3 and 5 ?
what would you type to check that 0 was (or wasnt) between 3 and 5 ?

[nirgrahamuk]

It seems that rather than reply to me, you are reposting the verbatim homework...
This is not advisable.

[AnnieRuser]

I don't know other way to describe it and this was not copy of my homework, i was describing with my own words what i need to do
Thank you anyway!

Luckily i still have whole weekend to figure this out.
