Hello gRoup, A while back I was advised that overallocating an object and filling it up is better than rbind.
I am trying to optimize some code. I have the following object (empty which I know in advance). Is there an easy to create an empty data frame with 100,000 empty rows based on the structure below? > dput(d) structure(list(A = character(0), B = character(0), C = numeric(0), D = character(0), E = character(0), F = character(0), G = character(0), H = structure(numeric(0), class = "Date"), I = numeric(0), J = integer(0)), .Names = c("A", "B", "C", "D", "E", "F", "G", "H", "I", "J"), row.names = integer(0), class = "data.frame") I can use dataFrame in R.utils and do it explicitly but wondering if there an easier way since I have the structure with me. Thank you. ______________________________________________ R-help@r-project.org 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.
