average X value of specific Y
Hello
I have a table describing butterfly range traits.
It is composed of three columns as below
Species name range size (X) latitude of range midpoint (Y)
There are 11 kinds of butterflies.
Each has its range size, and the latitude of each range midpoint ranges
from 9 to 19.
I would like to have the average range size of every degree of latitude.
For example, the average range

repeatedly crashing smbd when printing: broken pipe
for months, we keep fighting issues with smbd

Independent variables omitted in lm and glm
Dear List,
Some independent variable were missing in calculation using lm and glm
(gaussian).
(X= Y1+Y2+…..+Y16, Independent number: 16 variable)
However, those variables did work well in cor(X, Y) respectively.
str(dataframe) was also run to ensure that the variables were all numbers.
Moreover, the missing variables were different in lm and glm.
In lm, 3 factors were not taken into

cca in vegan (formula instead of community matrix data)
Dear List,
I tried to do cca based on species data and environmental variables (formula
instead of community data).
However, there was an error saying row sums must be >0.
I searched the previous related messages but found few solutions.
Please kindly help and thank you in advance.

Butterflies in mdct.c
In mdct.c there's some functions including some-point butterfly. In 32-point and 16-point there are calling of smaller-point function everytime twice on each half of data. When I looked on it I found that's just linear algebra. So it can be rewritten to matrix multiplication. Some one can say: there's optimization on in register working. But imagine there's one calling 32-point,

AIC in MuMIn
Hello,
I am using package MuMIn to calculate AIC for a full model with 10
explanatory variables.
Thanks in advance in sharing your experience.
Q1
In the AIC list of all models, each model is differentiated by model number.
Please kindly advise if it is possible to
find the corresponding explanatory variable(s) for the model number.

matrix operations
In R, I'm imported a data frame of 2,321,123 by 4 called "dataF".
I converted the data frame "dataF" to a matrix
dataM <- as.matrix(dataF)
Does R have an efficient routine to treat the special elements that
contain "inf" in them. For example, can you separate the rows that have
"inf" elements from the matrix into a separate matrix without

defining "id" argument in geeglm
Hi all,
I am trying to do a generalized estimating equation (GEE) with the "geepack"
package and I am not 100% sure what exactly the "id" argument means. It
seems to be an important argument because results differ considerably
defining different clusters.
I have a data set of counts (poisson distribution): numbers of butterfly
species counted every month during a period of

R-2.6.0 package check problems
Hello
One of my packages, untb_1.3-2, passes R CMD check under
MacOSX (and apparently the systems used in the package check
summary page on CRAN) but fails with the following message on
R-2.6.0.tgz compiled last night on my (home) linux box. I hasten
to add that I have never seen this error before on home-compiled
pre-releases of R-2.6.0.
Can anyone help me understand what is going on?

reinstalling R
Hi,
My question is: if I want to recompile and reinstall a newer version of R
under linux, must I remove the old binaries previously installed ?
If yes where are located them?
Thanks!

[RFC PATCH v1 0/3] Introducing ARM SIMD Support
libvorbis does not currently have any simd/vectorization.
Following patches add generic framework for simd/vectorization
and on top, add ARM-NEON simd vectorization using intrinsics.

Saving heatmaps as PDFs

mdct.c optimization
I took function mdct_butterfly_8 and write out transformation matrix. Then I rewrote this matrix into sequence of additions and substractions (see attachement). As I suspected I got the same as in the original code but I swaped some rows to get little higher speed. I hope I'll do the same with 16 point butterfly function combined with 8 point butterflies in a month. Who still believe that this
