[R] Hysteresis modeling and simulation

Can anyone suggest a package or code for modeling a hysteresis process in R? I'm currently modeling a certain dataset with a GAM using mgcv, something like gam(y~ s(x, by=z) + z, family = Gamma(link=log),data=data) and getting fits with about 9 estimated degrees of freedom in the smooth for eac

Re: [R] tzone and DST

x27;m not yet sure what happens in the fall. Is there a best practice for dealing with periodic (hourly, quarter-hourly, etc.) data that spans the DST change such that graphs of time series, etc., are easily understood? Thanks, Bill -- Bill Harris http://makingsense.facilitateds

[R] tzone and DST

I'm reading in ~3 years worth of data that includes hourly timestamps. Presumably to avoid DST confusion, all the data is in PST time zone -- no discontinuities in the spring or fall. The data comes in a csv file, which I'm reading with myvariable <- read.csv("my_data_file.csv",header=FALSE, col

auto example was made up; my real raw data is about a different subject and has far more columns, but I think I can abstract it down. Thanks again. I'll try those ideas out when I get the data in the correct format, and then I'll let you know if I have more questions. Bill -- B
