Hi Listers Using mvpart to run a MV regression tree with PCA= TRUE to get a PCA plotted with sites coloured according to the tree output. Unfortunately it wont produce the PCA, instead giving the error message.. Error in cor(xall, xx[order(tree$where), ]) : incompatible dimensions. However, whe

Re: [R] Export R outputs to SAS dataset

It is still not clear to me (1) if you just want the printed output in your SAS list file, or (2) if you want the actual numerical results returned to SAS so that you can do more manipulation with the numbers. If (1) you can precede your R code with sink() to output to your SAS list file  #-

Re: [R] Classification Tree Prediction Error

Purely statistical questions -- as opposed to R programming queries -- are generally off topic here. Here is where they are on topic: https://stats.stackexchange.com/ Suggestion: when you post, do include the package name where you get tree() from, as there might be more than one with this functi

[R] Classification Tree Prediction Error

Dear all R experts, I have a question about using cross-validation to assess results estimated from a classification tree model. I annotated what each line does in the R code chunk below. Basically, I split the data, named usedta, into 70% vs. 30%, with the training set having 70% and the test set

Hi Luis, As so often happens, the image didn't make it. Try PNG or PDF format. Without seeing what you want, it's only guessing. Jim On Mon, Aug 24, 2020 at 6:34 PM Luis Fernando García wrote: > > I am wanting to make a flow diagram like the one attached as an example for > the given dataset. >

[R] Help on plot from transition matrix

I am wanting to make a flow diagram like the one attached as an example for the given dataset. The idea is to plot a flow diagramm using the probabilities given by a transition matrix like the displayed in the example below. I have found some tools like DiagrammeR which might work for this purpose
