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