Hello,
I'm trying to learn R (for fun!), and I've tried to find any previous
discussion of this problem (or something like it) and haven't found one.
When I run the following command, R seems to simply stop. I get no error
message, but I also have no ">" or "+" to type after
(although I can
type). The only solution seems to be restarting the program. Here's the
code:
for(i in 1:150)
for(j in 1:150)
(average <-c(
(if(NO[i]==1)
{i*0}
else
{if(HA[i]==HA[j])
{while(G[j]==1)
{mean(PT[j:(i-1)])}}})))
Also, if what I'm trying to do makes any sense and someone sees an
easier way of doing it, that would be great.
Thanks!

But the problem appears to be your while loop: you never change the condition G[j] == 1, so that loop will continue indefinitely.

Hi r-help-bounces at r-project.org napsal dne 03.03.2010 08:27:27:> Hello, > > I'm trying to learn R (for fun!), and I've tried to find any previous > discussion of this problem (or something like it) and haven't found one. > > When I run the following command, R seems to simply stop.

When I used your code I got> for(i in 1:150)+ for(j in 1:150) + (average <-c( + (if(NO[i]==1) + {i*0} + else + {if(HA[i]==HA[j]) + {while(G[j]==1) + {mean(PT[j:(i-1)])}}}))) Error: object 'NO' not found ^^^^^^^^^^^^^^^^^^^^^^^^^^^^> > Also, if what I'm trying to do makes any sense and someone sees an > easier way of doing it, that would be great.And what really you are trying to do? Use R like C+? No way, forget it. R is R C+ is C+.
