[R] Separating lines in ts.plot()?

I'm using ts.plot() to plot a matrix of time series (each column is a ts). What I noticed is that ts.plot() creates a lot of overlapping lines which makes it difficult to distinguish different series. What options exist for making the series more easily read?

[R] Converting a matrix to an mcmc object

Dear List, I am using R2jags and post process some mcmc objects to produce a new object, which is currently a matrix, which replicates the shape of the objects from which it is derived. I want to produce a Gelman-Rubin graph from its (implied) three chains, but I need to coerce the matrix into

Re: [R] Extracing Unique Rows based on 2 Column

A logical expression applied to a vector (such as a dataframe column) gives you a logical vector that you can use for selection. You can combine several of these with the & (AND) and | (OR) operator. In your case, you apparently want a range of possible values. Use the %in% operator. Consider

Providing a reproducible example and the results of `sessionInfo` will help get your question answered. My only guess is that one or more of your predictors are factors and that the in-sample data (used to build the model during resampling) have different levels than the holdout samples. Max On
