[R] Fw: PROBLEM - - COMPARING AND COMBINING two DATASETS
Dear Sirs, ? At the outset I sincerely apologize for reproducing my query to you. I also thank all of you for the solution you had provided. It has worked on the actual data I am working with. ? However, there is this peculiar problem which I had realized only after I had obtained my results. ? e.g. in the example I had attached ? A?<-?c(2, 2, 1, 3, 7, 3, 3, 1,?14, 7, 31) B?<- c(0.0728,0.9538,4.0140,0.0020,2.5593,0.1620,2.513,0.3798, .0033,0..2282, 0.1614) ? tapply( B, A, sum) ? I get R output as ? ? ?1????????? 2????? ??? 3????? ???? ?7???? ?????? 14???? ???? 31 4.3938?? 1.0266?? 2.6770??? 2.7875??? 0.0033??? 0.1614 ? However, my requirement is I should get the output as ? 1 ?????????2????? ????3 ????? ??4 ?5 ?6 ?7?? ??????8 ?9 ?. 14 ???..31 4.3938 1.0266 ?2.6770 ??0 ?0 ?0 ?2.7875 ?0 ?0 ..0.0033 .. 0.161 ? i.e. my output should include the values 4, 5, 6, etc. which are not part of dataset A and the corresponding totals in B (which are anyways 0?s). I need this for my further analysis. Its possible for me to add these 0?s manually, however when the dataset is large, its not practical. ? I am attaching herewith an excel file. I will be grateful if you can guide me. ? Thanks in advance ? Maithili start: 2009-08-18 end: 0000-00-00 Thinking of ordering food? Find restaurant numbers on Yahoo! India Local Love Cricket?

Try this: tapply(B, factor(A, levels = seq(max(A))), sum) On Thu, Aug 27, 2009 at 9:26 AM, Maithili Shiva <maithili_shiva@yahoo.com>wrote:> > > > > > > > Dear Sirs, > > At the outset I sincerely apologize for reproducing my query to you.
