I have an ascii data set of monthly observation starting in Jan 1946 with a
header.
hstarts
57
65
95
103
103
97
94
.
.
.
Which I read with the following code
tab6.1<-ts(read.table(fname, header=TRUE),frequency=12,start=c(1946,1))
I would like to run a time series model with dummy variables for each month.
If I had a variable which take values from 1 to 12 indicating the month I
could use the factor() function to model the series.
reg1<-lm(hstarts~ -1 + factor(months))
Is there a function that will extract the year and month from a ts data set?
Thanks,
Richard Saba
