## loop

 Dear All, I have to use loop over an array  so I am using following procedure   count<-1  repeat{  count<-count + 1  c(g[count],1:i[count]) ->qw  if(count>5)break  } as  a result qw is [1]  0.9643836  1.0000000  2.0000000  3.0000000  4.0000000  5.0000000  [7]  6.0000000  7.0000000  8.0000000  9.0000000 10.0000000 11.0000000 [13] 12.0000000 13.0000000 14.0000000 15.0000000 16.0000000 17.0000000 [19] 18.0000000 19.0000000 20.0000000 21.0000000 22.0000000 23.0000000 [25] 24.0000000 25.0000000 26.0000000 27.0000000 28.0000000 29.0000000 [31] 30.0000000 31.0000000 32.0000000 33.0000000 34.0000000 35.0000000 [37] 36.0000000 37.0000000 38.0000000 39.0000000 which is according to the last value of  count i.e 6.

I suspect your problem is in initializing count improperly, or in putting the test in the wrong place.

## Re: loop

 In reply to this post by gynmeerut Your loop will store results of count =6 because every time the loop executes the results are put in qw so you replace the previous results.  On the other hand the results of count=1 is not extracted you basicaly start at 2. My advice is you initialize qw before the loop and stack the results one after the other e.g.  qw <-NULL  count<-1   repeat{  qw<-c(qw,  c(g[count],1:i[count]) )   count<-count + 1   if(count>5) break  } Kind regards Anthony Gichangi ----- Original Message ----- From: "gynmeerut" <[hidden email]> To: <[hidden email]> Sent: Thursday, December 29, 2005 1:41 PM Subject: [R] loop > > Dear All, > > I have to use loop over an array  so I am using following procedure > > count<-1 > repeat{ > count<-count + 1 > c(g[count],1:i[count]) ->qw > if(count>5)break > } > > as  a result qw is > [1]  0.9643836  1.0000000  2.0000000  3.0000000  4.0000000  5.0000000 > [7]  6.0000000  7.0000000  8.0000000  9.0000000 10.0000000 11.0000000 > [13] 12.0000000 13.0000000 14.0000000 15.0000000 16.0000000 17.0000000 > [19] 18.0000000 19.0000000 20.0000000 21.0000000 22.0000000 23.0000000 > [25] 24.0000000 25.0000000 26.0000000 27.0000000 28.0000000 29.0000000 > [31] 30.0000000 31.0000000 32.0000000 33.0000000 34.0000000 35.0000000 > [37] 36.0000000 37.0000000 38.0000000 39.0000000 > > which is according to the last value of  count i.e 6.
