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:

Thanks

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,
A
Perfect!
Thanks,
Ariel

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

Hypothesis regarding the thought process: integer is a perfect subset of
numeric, so why split hairs?

Hi Milu,
I just realized that by "the bottom of the map" you may mean "beneath
the map", in which case you should use:
par(xpd=TRUE)
arrows(...)
par(xpd=FALSE)

Indeed!
Slightly simplified to emphasize your point:
> class(as(1:2,"numeric"))
[1] "integer"
> class(as.numeric(1:2))
[1] "numeric"
whereas in ?as it says:
"Methods are pre-defined for coercing any object to one of the basic
datatypes. For example, as(x, "numeric") uses the existing as.numeri
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

Hello
I'm currently using the dbFD function of the FD package and i'm having some

Is there any way to check the relations between dbFD indexes?

Thank you very much for your replies! I didn't know about par('usr').
I get different coordinates though:

But the arrow is not at the bottom of the map. I will keep playing with
this. Thanks again!

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:
Dear R-list users,
I need to use strptime because I have to deal with date with hours and minutes.
I read the manual for strptime and I also looked at many examples, but when I
try to apply it to my code, I always encounter some problems.
I try to change the default format, with no success. Why? H
