You haven't even told us your OS, but it sounds like it might be
Windows.
In any case, RPostgreSQL is (like RMySQL) not distributed in binary
form, and you need to compile it from the sources against your
PostgreSQL version (which does matter, including the compiler used to
build it).

There is no doubt that you are right, but Anna's question only shows that

Dear Mark,
I'm cc'ing this to the mixed models list to get some input from other experts.
For them a link to the entire thread:

My comment was based on what I have read in Zuur et al. (2009).

Brian,
Thanks for the insights, i did manage to play around with the sample sizes and
I have got some better results with both ROCR and pROC
Thanks also to Andrija for providing the main code and insights.
Thanks alot

The following search:
library(sos)
findFn('confirmatory factor analysis')
finds several potential matches, the most direct of which appears to be the
cfa() function in package lavaan.

Hi:
Is this what you're after?
fout <- function(x) {
lim <- median(x) + c(-2, 2) * mad(x)
x[x < lim[1] | x > lim[2]]
}

Hi all,
I need to test the significnce of difference between slopes of two regression
lines and regression line with theoretical line. I try to use Slope.test
function from emu package,
but an error occured...
library(emu)
d1<-data.frame(P1=c(1,2,3,5,7,8,9,13,14,15),
P2=c(1,2,5,8,11,13,15,15,1
Hi all,
I need to test the significnce of difference between slopes of two regression
lines and regression line with theoretical line. Is it correct to use t-test in
this situation? Here is my script:
library(car)
d1<-data.frame(P1=c(1,2,3,5,7,8,9,13,14,15),
P2=c(1,2,5,8,11,13,1
Hi R-team,
While using R 2.12.2, I came across a problem that it doesn't have RPostgreSQL
package in the list of "install packages".
As my original code was written in R 2.11.1, I could use the RPostgreSQL
package.
I am moving to R 2.12.2 to use the newly added package "xtable" in newer
version
