In R version 2.15.2 (2012-10-26) i386-apple-darwin9.8.0/i386 (32-bit) I get
the following:
> a <- list(1)
> (a[[1]] <- a)
[[1]]
[[1]][[1]]
[1] 1
but
> a <- list(1)
> b <- a
> (a[[1]] <- a)
[[1]]
[1] 1
And similarly:
> a <- list(x=1)
> (a$x <- a)
$x
$x$x
[1] 1
but
> a <- list(x=1)
> b <- a
>
Okay, thanks for the input, All. I'd settled on the explicit coercion
as.data.frame as well as the myObject[] syntax which makes a lot of sense. I'd
also like to implement an as.double() method. However, I'm having trouble
embedding this into my package. In the R file I have:
setMethod("as.
Dear R-developers,
since R 2.15.2 Im getting an error with my RNetLogo package.
The package uses rJava and connects to the Java program NetLogo

When starting it in so-called GUI-mode, i.e.:
library(RNetLogo)
NLStart("C:/Program Files/NetLogo 5.0.3", g
To respond a little more directly to what you seem to be asking for:
You would like an "automatic" conversion from your class (you don't give us its
name, let's call it frameHDF for now) and "data.frame".
In R (and in OOP generally) this sounds like inheritance: you want a frameHDF
to be valid
