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?
