Counting things
I've completed an experiment and want to summarize the results.
There are two things I like to create.
1) A simple count of things from the data.frame with predictions
1a) Number of predictions with probability greater than x
1b) Number of predictions with probability greater than x that are
really true
In SQL, this would be,

[PATCH 0/3] Allow environment variables to have boolean values.
https://bugzilla.redhat.com/show_bug.cgi?id=1175196
Currently if you write something like LIBGUESTFS_DEBUG=0 or
LIBGUESTFS_DEBUG=true then it doesn't do what you probably expect.
This patch series fixes that.

Vary an equation using values from a sequence
Hi All,
I have a vector of data on which I am operating. The equation with which I want to operate on the vector has a value k. I want to run the equation and output a new vector, each time replacing k with each value from the sequence I defined. I have thought about using for loops and such, but this seems like overkill. I am wondering if there is a simple solution that would allow me to

[PATCH v2 API PROPOSAL 0/5] inspection Add network interfaces to inspection data.
The proposed API is the same as v1, but this includes an
implementation (for /etc/sysconfig/network-scripts/ifcfg-*) and
modifications to virt-inspector. This compiles and works.
If you look in patch 5 you can see proposed output as virt-inspector
XML for a guest (although this guest has not been booted, so a real
guest would hopefully have a hwaddr="MAC" attribute too).

CLI and DNIS presented to Analog extension
My company is based in Australia and we have a need to be able to
present CLI (ANI) and DNIS to an analog extension. Currently our PABX
vendor is saying they can only deliver CLI between the first and second
cadence.
The system will collect calls via an aggregate of ISDN PRI services from
the PSTN and then direct them to the analog extensions in a hunt group
configuration. It is important that

Vary an equation using values from a sequence
I thnk what you want is ?outer. e.g.:
outer(Data -min(Data),value,FUN = "+")
Whether this works for your real task, however, may depend on details and
complexities that you have omitted.
Cheers,

memory usage grows too fast
Hi All,
I have a 1000x1000000 matrix.
The calculation I would like to do is actually very simple: for each row, calculate the frequency of a given pattern. For example, a toy dataset is as follows.
Col1 Col2 Col3 Col4
01 02 02 00 => Freq of ?02? is 0.5
02 02 02 01 => Freq of ?02? is 0.75
00 02 01 01 ?
My code is quite simple as the following to find the pattern ?02?.

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
Hello Everyone,
I have three variables: Waist circumference (WC), serum triglyceride (TG)
level and gender. Waist circumference and serum triglyceride is numeric and
gender (male and female) is categorical. From these three variables, I want
to calculate the "Lipid Accumulation Product (LAP) Index". The equation to
calculate LAP is different for male and females. I am giving both

anyone know how to combine two vector with some # overlaped?
Hi, there,
Suppose I have two vector say x=c(1 2 3 4 5) and y=(2
3 6 7). Then I want to combine these two vector
together and get z=c(1 2 3 4 5 6 7) with 2 and 3 only
appear once. I want to extend this one to a general
case(say more than 100 elements in x and y and each
time I don't know which elements are the same). Do you
happen to know how to do this and which command should
use?
Thank

Well, something like:
LAP <- ifelse(gender =='male', (WC-65)*TG, (WC-58)*TG)
The exact code depends on whether your variables are in a data frame or
list or whatever, which you failed to specify. If so, ?with may be useful.
Cheers,

source definition for R_NilValue/return from TYPEOF(R_NilValue)
Hello,
for reasons I want to know the return value of TYPEOF(R_NilValue), I
expect it to be NILSXP, but I can't find this documented anywhere.
Ideally, I'd like to see the source definition of R_NilValue, but after
fair bit of searching I cannot find an obviously location for this.
Would someone please point me in the right direction?
thanks

Is there any design based two proportions z test?
Hello Everyone,
I was analysing big survey data using survey packages on RStudio. Survey
package allows survey data analysis with the design effect.The survey
package included functions for all other statistical analysis except
two-proportion z tests.
I was trying to calculate the difference in prevalence of Diabetes and
Prediabetes between the year 2011 and 2017 (with 95%CI). I was able to

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG))
That will do both calculations and merge the two vectors appropriately. It will use extra memory, but it should be much faster than a 'for' loop.

Jorgen Harmse.

The error message in package Mix
Hi all,
When using package MIX, I often get the error: NA/NaN/Inf in foreign
function call (arg 1).
For example,

or when I ran:

Numbers as symbols
I want to use question numbers from my survey data
(fake data below) as markers in a scatterplot. I'm
using "as.character" to convert question numbers to
characters. However, plot truncates the 0 (zero) off

add questions 11 - 20?

Reset trellis plot backgroud color
Hello,
I run R on Windows 2000. When I load lattice library and plot some lme class
objects, the graphic window displays a dark-green color. Graphics look ok on
the screen, but lines and points become invisible whem I send the plot to a
printer because of the background color. Are there ways to reset the
background color? Both par(bg=) and windows() do not work. Any ideas?
