during fitting of successive datasets, stall crashes iterations
...plot(y ~ x, xlab = "Time (h)", ylab = Lumi, pch = 15)
# fitting algorithm looks like this:
sine<- nls (y ~ baseline + trend*x + amplitude*(sin(2*pi*(x+phase)/period)),
start=list(baseline=4000, amplitude=4000, phase=0, period=24, trend=0),
trace=TRUE)

I am exploring the alternative of making an immense dataframe, and I'm
trying to get through the R language definition documentation to build
these functions--any expert advice would be tremendously helpful.
Thanks for your time.
