We haven't seen the actual call to the function, singleCosinor(), in your code so we can't say for sure what the problem is. However, the confusion may be that while there is a formal parameter named y, it does not refer to any variable named y in the global environment. If you have a variables t and y in the global environment, then the call would need to be singleCosinor(t=t, y=y) hope this is helpful, Dan Daniel J.
