Re: [R] forecasting

Hi DM, I'm currently dealing with very similar issues. To date I've been exporting regression outputs in mass quantities (updated every 5 days) to excel, and manually linking to data to get my predictions. I've been doing a ton of research on forecast, caret, and SEM packages and am still empty

Re: [R] Consistent size dashes...

If you rename two or more levels with the same string, R collapses them. Using gsub like you suggest works well. If there are more than the two characters causing problems you may need to expand the pattern that's being matched. With the example you sent, this works: df <- structure(c(6L, 4L,

Hi, a reproducible example would help us to help you. In any case, you might want to consider a for-loop in combination with par(mfrow = c(?, ?)). The lattice or ggplot2 package might also provide a solution to your problem. Cheers, Jannes -- View this message in context: http://r.789695.n4.

This is a question about statistics theory, not about R, so it is off topic here... you might try discussing this at the CrossValidated forum. In general, the amount of lag that is relevant depends on how you intend to use the data. This is not unlike the application of linear models to nonlinea
