With rw2010dev I get a strange protect(): protection stack overflow
error with a small data frame which otherwise is usable:
If anybody wants to have a look I can provide an RData file
with the problematic data frame.
Doesn't seem to be necessary, the following simulated example
generates the error:
> testmat <- matrix(1:80, 20,4)
> dim(testmat)
[1] 20 4
> str(testmat)
int [1:20, 1:4] 1 2 3 4 5 6 7 8 9 10 ...
> testframe <- data.frame(testmat=I(testmat),
x=rnorm(20), y=rnorm(20), z=sample(1:20))
> str(testframe)
`data.frame': 20 obs. of 4 variables:
$ testmat: int [1:20, 1:4] 1 2 3 4 5 6 7 8 9 10 ...
..- attr(*, "class")= chr "AsIs"
$ x : num 0.768 -0.462 0.450 0.476 -1.077 ...
$ y : num 0.453 1.227 -1.514 -0.904 -0.129 ...
$ z : int 10 4 15 19 14 3 9 17 18 5 ...
> summary(testframe)
