was trying to match different matrices of different lengths with in the first collumn date and time info (yearmonthdayhourminute). the routine needs to return NA´s where data of either of the matrices is non existent.
have been trying the following: #### x <- c(200112030003, 200112030004, 200112030005, 200112030006) y <- c(0.1, 1, 1.1, 1.5) a <- c(200112030004, 200112030005, 200112030007, 200112030008, 200112030009) b <- c(1.2, 1.9, 2.0, 2.5, 2.1) xx <- cbind(x, y) aa <- cbind(a, b) xxnew <- ts(xx) aanew <- ts(aa) cc <- ts.union(xxnew, aanew) cc #### this does however not give the wished for result as it simply cbinds the two matrices and filles up empty spots that are created due to the one matrix being shorter then the other at the bottom end of the shortest matrix. i realy want the routine to match matrix xx and aa to time in the first collumn of both matrices. any help towards this end would be much appreciated, th. ______________________________________________ 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.
