Adam: > Providing a reproducible example would be a first step... That's the problem, I can't. But I str has come to the rescue:
R > str(rw) Time-Series [1:307] from 1690 to 1996: 0.986 1.347 1.502 1.594 1.475 ... R > str(pg) List of 264 $ : num 0.227 $ : num 0.189 $ : num 0.237 $ : num 0.235 . . . . - attr(*, "dim")= int [1:2] 22 12 - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:12] "Series 1" "Series 2" "Series 3" "Series 4" ... - attr(*, "tsp")= num [1:3] 1982 2003 1 - attr(*, "class")= chr [1:2] "mts" "ts" Why is pg a list? pg was created by taking a row out of a much larger data.frame: R > pg <- ts(matrix(monthly.pg[1,-c(1:4)], ncol = 12, byrow = T), start = 1982) R > class(pg) [1] "mts" "ts" R > mode(pg) [1] "list" So, changing the mode to numeric, allowed me to intersect the ts: R > pg <- ts(matrix(as.numeric(monthly.pg[1,-c(1:4)]), ncol = 12, byrow = T), start = 1982) R > tsp(ts.intersect(rw, pg)) [1] 1982 1996 1 Weird. I suppose keeping on top of every object's mode is important. Thanks for the push forward. -Andy ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
