Thank you for your reply.
Yes, there is a problem according to you suggestion.
What if the value are not numerical, e.g. I want to use the variable to
store the results of linear regression.
can I use
myvec <- vector( "numeric", 10 )
for ( i in 1:10 ) {
myvec[ i ] <- summary(lm(y~x)) # y and x are different values in each
loop.
}
?
you advice seems only to be available when the function left allocates a
numerical value to the variable, what if the function return other type of
objects?
