I'm trying to convert a column of a table into a ts object. The data is
monthly, so I want the ts frequency to be 12.
I did this ...
filings.ts = as.ts(Filings.100K, frequency=12)
Use the constructor function ts(), not the coercion function as.ts(). The
latter does not have a frequency argument. See ?ts.
filings.ts
Time Series:
Start = 1
End = 311
Frequency = 1
[1] 246.9336 305.6789 ... ...
tsp(filings.ts)
[1] 1 311 1
tsp(filings.ts) <- c(1,311,12)
Error in attr(x, "tsp") <- value :
invalid time series parameters specified
What am I doing wrong here?
Not reading the documentation?
c(1, 311, 12) are not valid time series properties because it would imply
that your series as length 311 * 12 + 1, which is not the case.

I can't seem to be able to change the frequency
from 1 to 12. Thanks!
