Holt Winters Error
That's not an error, but a line of R code. If you could post an example which generates the error and the actual error message, we could try to investigate it.

I have come across with the following error while running HoltWinters(). optim(c(0.3, 0.1, 0.1), error, method = "L-BFGS-B", lower = c(0, 0, 0), upper = c(1, 1, 1)) It only happens to multiplicative seasonality but not additive. I read the program but still couldn't understand it.
