tsoutliers软件包中的tso函数语法问题

Question

I have a data frame (3575 observations long) with two columns, Date and Oxygen Concentration. Date is in YYYY-MM-DD format for 25 years and oxygen values are numbers running anywhere from 0.05 to 7.5. I'm trying to locate outliers in my dataset using the tsoutliers package and my problem is with the syntax and not the values of the data themselves.

I first used the auto.arima function with this code:

auto.arima(Site7$Oxygen, seasonal = TRUE, stepwise = FALSE)

I'm sorry about not being able to give a minimum reproducible example but given the scale of the data and tests, it would be quite difficult to put it all in here.

For the results I got:

Series: Date$Oxygen  
ARIMA(3,1,2) 

Coefficients:
         ar1     ar2     ar3      ma1      ma2
      0.2988  0.2439  0.1431  -0.4348  -0.5259 
s.e.  0.0947  0.0686  0.0316   0.0948   0.0772

sigma^2 estimated as 0.5999:  log likelihood=-4145.53 
AIC=8303.06   AICc=8303.09   BIC=8340.15

Now, as I'm trying to visualize Additive Outliers I used the tso() command with this code:

AOoutliers <- tso(Date$Oxygen,types = "AO", maxit = 10, tsmethod = c("arima"), args.tsmethod = list(order =c(3,1,2)))

I now have this error which I can't seem to figure out:

Error in tso0(x = y, xreg = xreg, cval = cval, delta = delta, n.start = n.start, : trying to get slot "y" from an object of a basic class ("numeric") with no slots

Any help would be greatly appreciated. Thank you.
