Hello! I have a question regarding the cumsum function that I do not know how to solve. Would appreciate help from someone. I have imported data from a txtfile with 2 columns. I am interested in the seconds column, which contains numbers from i=0 to 40. I would like to count the number of instances of the numbers 0 to 40 in the seconds column. My problem is that if there are no observations of one number i in the second column cumsum skips this in the output.
Below is an example of the output of the argument Y=cumsum(table(x[,2])) 0 1 2 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 3 5 6 10 13 14 16 18 21 25 27 30 32 35 38 40 42 54 105 233 306 341 383 417 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 441 468 487 502 518 532 542 546 552 564 566 574 578 584 591 594 As you can see from the output there are no observations of i=4 in this column. Are there any way I could return the following result instead 0 1 2 3 4 5 6 7 8 and so on 3 5 6 10 10 13 14 16 18 When i=4 cumsum is the same as when i=3 (10) I would really appreciate if anyone could help me with this one:) Jan Moberg ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
