R help - Mar 2010 - If else statements

Hi everyone! 
May I request again for your help? 
I need to make some codes using if else statements...
Can I do an "if-else statement" inside an "if-else
statement"? Is this the
correct form of writing it? 
Thank you.=)

Example:

for (v in 1:6) {
for (i in 2:200) {
if (v==1)
(if max(x*v-y*v)>1 break())

if (v==2)
(if max(x*v-y*v)>1.8 break())

if (v==3)
(if max(x*v-y*v)>2 break())
}
}

The short answer is yes, you can, but your syntax is wrong.  You need
to make sure you wrap your conditions inside brackets, and use {, not
(, to delineate your if statements.
> for (v in 1:6) {
> for (i in 2:200) {
> if (v==1){
   if (max(x*v-y*v)>1)
     break()
  }
  }
  }
 et cetera
