This is some interesting:

So, can anybody explain this?! (Why is x[1]^(1/3)=y[1]=NaN, but
-8^(1/3)=-2?)
Thx!!!

reflecting a PCA biplot
Hi Listers,
I am trying to reflect a PCA biplot in the x-axis (i.e. PC1) but am not
having much success. In theory I believe all I need to do is multiply the
site and species scores for the PC1 by -1, which would effectively flip the
biplot.
I am creating a blank plot using the plot command and accessing the results
from a call to rda. I then use the calls to scores to obtain separate site

The model has inc, mic and spp are independent variables and vial nested within spp. inc and spp are already coded as factors since they were

Can I index a dataframe with a reference from/to a second dataframe?
Hello,
I am unable to figure out how to code a new column in a data frame based
on an existing column that matches a column in a reference data frame,
in a relational-db fashion. I would like this to maintain a minimum set
of reference tables that may be reused over several similar datasets.
Specifically, I have two data frames as listed below, 'Bos' and 'tree.'

PlaceSafepoints, operand bundles, and RewriteStatepointsForGC
[+CC llvm-dev this time]
Hi,
As discussed in the review thread in http://reviews.llvm.org/D16439,
the future plan around statepoints, deopt bundles, PlaceSafepoints
etc. is to "constant fold" -spp-no-statepoints
and -rs4gc-use-deopt-bundles to true.
We (Azul) have moved to a representation of safepoint polls, deopt
state etc. that enables us to do the above; and at this point I'm

logit regression, test among groups
Dear all:
My logistic regression model includes one qualitative and one quantitative
predictor variable,
aes <- glm(p.a ~ spp * log(light), family=binomial(link=logit)),
where spp is abundance of 3 species and light is subcanopy light
availability varying from 0 1.
I want to test differences among levels of the quantitative variable at a
value of x other than the current log(light)=0.

BIO-ENV procedure
I've been unable to find a R package that provides the means of
performing Clarke & Ainsworth's BIO-ENV procedure or something
comparable. Briefly, they describe a method for comparing two separate
sample ordinations, one from species data and the second from
environmental data. The analysis includes selection of the 'best'
subset of environmental variables for explaining
