arrays of arrays
Hello Sachin, You have a "ragged array" and you can easily store this as a list of vectors... x <- list(c(0,0,1,1), c(1,3,5), 4, c(7, -1, 8, 9, 10, 6)) The only gotcha with this is that you will then need to use double brackets for the first index when retrieving values (single brackets will return a vector wrapped in a list)... e.g. x[[2]][3] gives 5 You can query vector length with double brackets... e.g. length( x[[2]] ) gives 3 Hope this helps, Michael

Hi Erik, Thanks for replying. Only problem with that is that each row has 5 elements (or 5 columns). I want varying number of columns as shown in my example. x<- ? ? ? ? ? ? ?0 ? ? ? ? ? ? ? 0 ? ? ? ? ? ? ? 1 ? ? ? ? ? ? ? 1 ? ? ? ? ? ? ? ? 1 ? ? ? ? ? ? ? 3 ? ? ? ? ? ? ? 5 ? ? ? ? ? ? ? ? 4 ? ? ? ? ? ? ? ? 7 ? ? ? ? ? ? ? -1 ? ? ? ? ? ? ?8 ? ? ? ? ? ? ? 9 ? ? ? ? ? ? ? 10 ? ? ? ? ? ? ?6 Regards, Sachin p.s. sorry about corporate notice. --- Please consider the environment before printing this email --- Allianz - Best General Insurance Company of the Year 2010* Allianz - General Insurance Company of the Year 2009+ * Australian Banking and Finance Insurance Awards + Australia and New Zealand Insurance Industry Awards This email and any attachments has been sent by Allianz Australia Insurance Limited (ABN 15 000 122 850) and is intended solely for the addressee.
