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,
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
Creo que el problema se podría simplificar y aún obtener un resultado
aceptable si simplemente haces un ajuste lineal en un entorno del punto.
Como ya tienes los valores de los puntos de cada curva como dices
Carlos, creo que con esa información podrías identificar un entorno
adecuado en el
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

Hola Manuel,
Resolver el punto de corte de forma analítica implicaría el tener ajustada
cada densidad también de forma analítica.
Una alternativa que se me ocurre es la siguiente:
- Con la función "density()" ajustar la densidad de las presencias y las
ausencias.
- Con esta función
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
Add the arguments type="source" and repos=NULL to your call to
install.packages(). repos=NULL means that this is a local file, not
something to download from a repository.

I am struggling to install a fix for the rNOMADS package which reads National
Weather Service data. I copied the fix (rNOMADS_2.5.0.tar.gz) from an email to
a local drive and then tried to install it with the command below. I also
tried installing it without the .tar.gz extension and without
Buenas tardes, tengo una variable bimodal (*var)*, de presencias y
ausencias (1s y 0s) y otra variable, *prob*, con las probabilidades que le
asigna un modelo (entre 0 y 1).
Con: *ggplot(Preds, aes(x=prob, fill= var )) + geom_density(alpha=.3)*
obtengo la distribución de las presencias y de las
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.

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
Thank you so much!
