[R] Random Forest classification

Hi, To evaluate the partial influence of a factor with a random Forest, wich response is OK/NOK I�m using partialPlot, being the x axis the factor axis and the Y axis is between -1 and 1. What this -1 and 1 means? An example: https://www.dropbox.com/s/4b92lqxi3592r0d/Captura.JPG?dl=0

Buenas, Cuando estoy haciendo un random Forest para clasificaci�n y hago el gr�fico partialPlot, siendo mi respuesta OK/NOK, me sale en el eje X el valor de la variable, pero en el eje Y me salen valores de entre -1 y 1. �Qu� significado tiene? Adjunto un ejemplo:

Re: [R] [FORGED] Re: identical() versus sapply()

Hi Duncan, That explains it, thanks! I rarely use as(), but had thought in this case, replacing identical(x, y) with identical(x, as(y,class(x))) could be an sapply-friendly way to iron out class differences -- then noticed the inexplicable result. But now I know about all.equal(). Thanks,

Use all.equal instead of identical if you want to gloss over integer/numeric class differences and minor floating point differences (and a host of others). Bill Dunlap TIBCO Software wdunlap tibco.com On Mon, Apr 11, 2016 at 5:25 PM, Paulson, Ariel wrote: > Hi Jeff, > > > We

Hi Jeff, We are splitting hairs because R is splitting hairs, and causing us problems. Integer and numeric are different R classes with different properties, mathematical relationships notwithstanding. For instance, the counterintuitive result: > identical(as.integer(1), as.numeric(1))

Ok, I see the difference between 1 and 1:2, I'll just leave it as one of those "only in R" things. But it seems then, that as.numeric() should guarantee a FALSE outcome, yet it does not. To build on what Rolf pointed out, I would really love for someone to explain this one: > str(1) num 1

Hi Stefano, As the help page says: "The default for the format methods is "%Y-%m-%d %H:%M:%S" if any element has a time component which is not midnight, and "%Y-%m-%d" otherwise. This is because when the result is printed, it uses the default format. If you want a specified output representation:
