hello,
This rbindlist(list(list(a=NA,b=NA),list(a=20,b=FALSE))) returns a b 1: NA NA 2: TRUE FALSE as per the documentation ?rbindlist is there a way to specify the column class of 'a' to be numeric? In actual usage, i wont be able to re-order the 2nd list entry to be the first. I did try rbindlist(list(list(a=numeric(0),b=logical(0),list(a=NA,b=NA),list(a=20,b=FALSE))) but got a b 1: NA NA 2: TRUE FALSE This worked mu = rbindlist(list(list(a=numeric(1),b=logical(1),list(a=NA,b=NA),list(a=20,b=FALSE))) mu = mu[-1,] Is there a way to specify up front the classes rather than the last approach Regards Saptarshi [[alternative HTML version deleted]] ______________________________________________ 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.
