Hi,

 

I'm a complete beginner to all this so I was hoping someone could help
me!

 

What I'm trying to do is to write a function that returns the
coordinates where a vector x is equal to a.  So say I invent a vector x:


x<-c(,5,8,9,8,3).

If a is a<-8.

 

I want the function to return the coordinates of x where the number 8
appears (i.e. 2 4).

I know I need to set up an if loop but I'm really not sure how to do
this.

 

Any advice or clues will be much appreciated.

 

Thanks,

 

Laura
