passing function parameters into a 'with' statement to dynamically pick out columns
Hi,
I've built a function to generate plots and would like to be able pass in column names as a parameter. Here's a boiled down version of what I have right now:
pmts <- data.frame(date=c(1,2,3), all=c(5,6,7),maj=c(4,5,6),ind=c(3,4,5))
perc.mktshare <- function(df){
range1 <- floor(min(with(df, 100*ind/all)))
range2 <- ceiling(max(with(df, 100*ind/all)))

using color coded colorbars for bar plots
Hello R Fundi,
The poetic title of this post is a request for help in regard to a
"simple" plotting question.
I have displayed the mean observations of a series variables using
barplot(). On the same figure I have colored the bars to represent the
Standard deviation of each variable using color.scale(). Now I wish to
add a graduated colorbar (legend) that corresponds to the colors

R sequence function (was: Re: [R] Recursive decreasing sequences)
This seems a lot faster than using the R sequence function. Suggest
that sequence be rewritten.

Recursive decreasing sequences
Hello fellow R's,
I'm sure there must be an easy way to do this. But after digging in the
documentation and thinking about it for a while I couldn't figure it
out. I need to get a decreasing recursive vector in. I mean something
like this: if starting at 2, and ending at 6, the vector should be
2 3 4 5 6 3 4 5 6 4 5 6 5 6 6
An easy way would be to do this

Multiple Serial Port Passthrough in HVM domU
So, I made a mistake a bought four systems with the Intel Core i3 processors, without doing my homework to make sure that these systems actually supported VTd. Turns out there''s plenty of information out there indicating that the Core i3 processors do *not* support VTd. I was counting on VTd for two applications: Graphics Passthrough and passing through a PCIe 4-port serial card. Of

Kolmogorov-Smirnov-Test on binned data, I guess gumbel-distributed data
Hi R-Users,
I read some texts related to KS-tests. Most of those authors stated, that
KS-Tests are not suitable for binned data, but some of them refer to 'other'
authors who are claiming that KS-Tests are okay for binned data.
I searched for sources and can't find examples which approve that it is okay
to use KS-Tests for binned data - do you have any links to articles or

Does Xapian support query string like "(age: 1..25) OR (age: 35..50)"? or "(age: 1..25) - (age: 35..50)"?
Hi, All
Does Xapian support query string like "(age: 1..25) OR (age: 35..50)"? or "(age: 1..25) - (age: 35..50)"?

I?tested,?"(age: 1..25) OR (age: 35..50)"? or "(age: 1..25) - (age: 35..50)" doesn't work.

nls number of explantory variables
Hi..
is there a limit on the number of explanatory variables in nls ?
i have a dataframe with the columns names x1,x2..,x300
when i run nls it gives the error: " x181 not found"
thought it does run when i have x1,x2,...,x170 variables.
Thanks

Some questions about Letor project
Hi all,
Thank you for giving me the opportunity to work with Xapian :) I am Jiarong

GSoC 2014, I will work on Letor module with Hanxiao Sun.
Here are some questions I encountered these days,

the ranking part. I?ll use SVMRanker as an example. The

Questions on letor module
Hi,
I have several questions regarding the letor module,I looked at the
framework of learning to rank in xapian
http://rishabhmehrotra.com/gsoc/17.png, I am a little confused. Why using
deep learning to find unsupervised features in test data? Since in my
understanding, learning to rank model usually learn features from the
training data then apply the model to the test data? Why test set and

Letor: Post Mid-Term plan
Hello Rishabh,
As per our previous discussion, we will talk each week now about the
project. Please update the timeline/todo/journal accordingly so that we can
check the status on this saturday for this week.
Please remember that this half of the programme is smaller and hence we
would need to be very punctual about the goals.
Regards,
Parth.

Contributing to Xapian
I use Ubuntu12.04, GNU Make 3.81 and I am not sure if I use some special
configure options. The commands I use after clone the repo are as follows:
cd xapian
./bootstarp
./configure
make
cd xapian-letor
aclocal -I ../xapian-core/m4
libtoolize --force
autoconf
autoheader
automake --add-missing
./configure
make
Is this normal?

[LLVMdev] Keyword documenation for target, deplibs ...
Hello,
My goal is to create a language which can compile itself, therefore I
feel I need to understand the Assembler/Byte code format.
Starting with a C hello world program there are statements at the
beginning of the disassembled bc file that I couldn't find any
documentation:

target pointersize = 32
target triple = "i686-pc-linux-gnu"

Is the project learning to rank need to be improved?
As Olly has already pointed out the 2012 branch is not merged.
I think there are some compilation errors in the branch.
The code in branch is better refactored. The Ranker and FeatureManager
classes are well defined and implemented.
Parth.

Strange Estimates from lmer and glmmPQL
I'm trying to fit a generalized mixed effects model to a data set where
each subject has paired categorical responses y (so I'm trying to use a
binomial logit link). There are about 183 observations and one
explanatory factor x. I'm trying to fit something like:
(lmer(y~x+(1|subject)))
I also tried fitting the same type of model using glmmPQL from MASS. In
both cases, I get a

Categorical Response Query
Hi all,
I have a queston about Categorical response.
i have a data frame containing age, sex, class, success(1=success,
0=non sucess).
age, sex,class are the explantory variables, and sucess is the
response variable. and i can get n (the nunber of times each age
occurs) and r (the number of sucess of that age).
when I try to creat the regression relationship for these variables, I
have seen
