tseries to csv or xls
thx for the help. write.zoo may help me a lot with some other beginner issues i have, but I need to convert it into a data.frame though. I`d like to write stata files or .xls files and both functions need data.frames as a basis. best matt Am 17.11.2009 um 11:49 schrieb Gabor Grothendieck:
Using the built in AirPassengers data that comes with R this works:
AP12 <- ts(matrix(AirPassengers[], nc = 12, byrow = TRUE), start(AirPassengers)[1]) colnames(AP12) <- month.abb library(zoo) write.zoo(as.zoo(AP12), sep = ",")

Hi all,
is there a common way to write time series objects generated by ts() to some .csv or .xls.
write.table does not work by default since it expects a data.frame which a ts object is not.
Therefore write.table creates a data.frame which basically ignores the rows and columns of ts objects and just saves one big vector.
What I want to do is export it, the same way as a ts object is printed on console, like this:
Qtr1 Qtr2 Qtr3 Qtr4
1990 1.80926644 1.57801902 -0.06466631 -0.89682263
1991 0.38314894 0.58986441 0.61502833 1.55998143
1992 1.34689938 -0.61304408 2.17411932 0.13529151
1993 -0.07747732 1.76763799 0.37560837 0.36530430
1994 -1.03461000 0.88674850 1.71258524 0.79961787
I hope email transmission does not blow the formatting :) Thx for any help in advance
