Subject: [Rd] strange error with rw2010dev
Message-ID: <4248AC1A.3020104@acelerate.com>

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)
Error: protect(): protection stack overflow
