Greetings. The following code produces a segmentation fault in my installation of R 3.2.1 under Windows 7 (64-bit). Since rpart is "recommended" I figured I should report this here.
x <- rnorm (100)
rpart (x ~ x)
Perhaps these are a clue?
1: In model.matrix.default(attr(frame, "terms"), frame) :
the response appeared on the right-hand side and was dropped
2: In model.matrix.default(attr(frame, "terms"), frame) :
problem with term 1 in model.matrix: no columns are assigned
The segfault occurs in a C routine in the contributes rpart package.
Please report to the package maintiner.
Isn't this a "Core-supported package" ?
It is not. Look at the result of
or the CRAN web page for rpart.
Specifically, it ia a _recommended_ package, which is not quite the same thing as a core-maintained package. In particular, it is the maintainer who builds the package and submits to CRAN. Of course, anyone is welcome to help with debugging.
Thanks. So then I take it that for bugzilla reports, the maintainer really does need to be "R Core Team" rather than an individual member of said team? In that case, should other such reports be closed as well, for example:
