Re: [R] How to convert array dim names to expressions for plotting?

It is not clear to me what you mean by "expressions" in this context. Dimension names but be character strings -- see ?dimnames, which says: "The dimnames of a matrix or array can be NULL or a list of the same length as dim(x). If a list, its components are either NULL or a character vector with p

[R] How to convert array dim names to expressions for plotting?

Hi, I would like to use the dim names of an array as labels in a plot. In the case of character labels, this is no problem. However, if I would like to pass expressions through array dim names, they only appear as character labels in the plot and are not evaluated as expressions (see the minima

Re: [R] Text to Speech In R

Please don't shout. Speech synthesis is associated in my mind with sound generation, which is rather platform-specific. R is a platform agnostic research tool. R can be interfaced with many kinds of external libraries, so many things are possible. However, they aren't necessarily simple, and hi

[R] Is there any package for Vector Auto-regressive with exogenous variable other than fastVAR?

Package dse also does vector auto-regression with exogenous variables (and also vector ARMA and state-space models with exogenous variables). But I don't understand what you mean by "not taking the base in the model" so I don't know if it will solve your problem. Paul On 12-10-04 06:00 AM, r
