Hi R users,
 Maybe the question is too simple.
 In a IF ... ELSE ... statement "if(cond) cons.expr else alt.expr", IF and 
ELSE should be at the same line? 
For example,
 if (x1==12)
{
y1 <- 5 
}else
{
y1 <- 3
}
 is right, while
 if (x1==12)
{
y1 <- 5 
}
else # Error: syntax error
{
y1 <- 3
}
 is wrong? 
 Thanks
