bwplot questions: box order, axis breaks, and multiple y-axis labels
Hi all,
I used bwplot in lattice to create a 6-panel boxplot grouped by a
conditioning variable (param) that displays concentration (conc) in
response to treatment (trtmnt). Here is the functional part of my
code followed by my three questions:
library(lattice);
ww<-read.csv(file="c:/Rdata/lattice_boxplot_prep.csv",header=TRUE,sep=",");
attach(ww);

bug found in predict.locfit in locfit package ( PR#8057)
Apologies for the coming to this late...
1. By now I hope Somkiat has realized that R-bugs is not the place to
report problems in contributed packages. Please direct such reports to
the package maintainer.
2. This is really user error. predict() expect the newdata to be a data
frame containing variables with the same names as those used in the
fitting process. E.g., you fitted the model with

L2ARC & Workingset Size
Hi all
I ran a workload that reads & writes within 10 files each file is 256M, ie,
(10 * 256M = 2.5GB total Dataset Size).
I have set the ARC max size to 1 GB on etc/system file
In the worse case, let us assume that the whole dataset is hot, meaning my
workingset size= 2.5GB
My SSD flash size = 8GB and being used for L2ARC
No slog is used in the pool

Discriminant Analysis- Apparent error rate
R-help,
I'm trying to evaluate the misclasification rate

Perl516 SCL modules
Hi,
I'm trying to build several SCL perl516 modules for using assp spamfilter.
Some modules have dependencies which spend a lot of errors or can not be
build on a x86_64 system.
perl-Email-Valid-0.184 for example needs Win32::IPHelper and
Win32::TieRegistry.
If I build this rpm for standard perl510, the Win32 modules are not
required.
Why are theses dependencies only for perl516?

Check for is.object
Hello,
I am trying to recursively append some data from multiple files into a
common object
For this, I am using in a loop
NewObject <- rbind(NewObject,tempObject)
For the first loop, obviously there is no NewObject ... so I wanted to do
NewObject <- tempObject[0,]
Now when it loops again I want to put the statement do "NewObject <-
tempObject[0,]" inside a if statement

Systematically biased count data regression model
Dear all,
I am attempting to explain patterns of arthropod family richness
(count data) using a regression model. It seems to be able to do a
pretty good job as an explanatory model (i.e. demonstrating
relationships between dependent and independent variables), but it has
systematic problems as a predictive model: It is biased high at low
observed values of family richness and biased low at

write.table problem
