Formula variable help
Seems like it could work---can you save your script as a .txt file and send it as an attachment, upload it online, or make a reproducible example? Cheers, Josh

I have an R script with the following applicable lines:
? ? ? ? ? ? ? ?xshort <- window(s, start=st, end=ed)

? ? ? ? ? ? ? ?xshort <- ts(xshort, frequency=1, start=1)
. . .
? ? ? ? ? ? ? ?m1 <- m2 <- m3 <- m4 <- m5 <- m6 <- NULL
? ? ? ? ? ? ? ?m1 <- tslm(xshort ~ trend)
I get an error:
Error in get(dataname) : object 'xshort' not found
When I do traceback() I get:
3: get(dataname)
2: tslm(xshort ~ trend) at #19
1: model.cross.validation(l[["MEN"]]$series)
Which points to the call to tslm above. ?Since I am not supply 'data' to
the tslm call (in the forecast package),, I am assuming that the code is
dying here (in tslm):
? ? if (missing(data)) {
? ? ? ? dataname <- as.character(formula)[2]
? ? ? ? x <- get(dataname)
? ? ? ? data <- data.frame(x)
? ? ? ? colnames(data) <- dataname
? ? }
Any ideas what is failing?
