Hi: The essential problem is that after you append items, the result is a list with possibly unequal lengths. Trying to convert that into a data frame by the 'usual' methods (do.call(rbind, ...) or ldply() in plyr) didn't work (as anticipated). One approach is to initialize a maximum size matrix w

Thanks Dennis. One more thing if you don't mind. How to I abstract the individual H and T “arrays” from f(m,o,l) so as I can combine them with a date/time array and write to a file? Sorry if it’s a simple question but I’m completely new to R. Cheers, Doug -- View this message i

Dennis, Thanks for that. The problem now is that I am trying to use it in a for loop. Based on the example before, 2 entries are required after H[3] as specified by O. The problem is that when inserting values the length of the array changes so I don't know how to tell the loop that. This is

R community, I am trying to write a code that fills in data gaps in a time series. I have no R or statistics background at all but the use of R is proving to be a large portion of my PhD research. So far my code identifies where and the number of new entries required but I do not know how to ad
