Hi, I'm trying to use R's DBI interface but it appears to be broken. I am
using R 1.8.0 on Linux, and have just installed DBI 0.1-6 through the command
'install.packages("DBI")'.
Installation went fine, but now when I try to do a simple dbConnect(), it
won't do anything besides
I am running the following code (testing the use of the simplex function to
determine if a point is in the convex hull of another set of points or not):
>a <- c(0, 0)
>A3 <-matrix(c(1,2,3,4,1,1), ncol = 2, byrow = T)
>b3 <-c(1.5, 3.5, 1)
>simplex(a = a, A3 = A3, b3 = b3)
and the following error
Thank Andy Liaw for his response to my enquiry. He suggested creating the
tar.gz source package at the parent directory of the fixed code using
R CMD build GLMMGibbs
and then R CMD INSTALL GLMMGibbs to install the package. The package is now
installed and works fine.
Thanks Andy,

Look at ?points. And you can set col = for most plotting functions.

How about

Hi,
we have some code that does variable selection with a genetic
algorithm or simulated annealing, using a linear regression routine or
neural network as the objective function. This code is a mixture of
fortran and C.
The code is more than 15 years old and I am planning to rework it.

Hi Guys
This is a combined Perl/R question, hopefully there are enough people out there who
use both to help me. I am using the latest versions of both on a SUSE Linux 8.2
machine.
I am wrapping up R in some very simple perl scripts. My problem is that when I run a
series of commands from wi
Hello everyone,
I am trying to calculate predicted values for a fit from rq (quantreg; see
my earlier post), but I am having trouble understanding how to interpret the
coefficents in the summary.rq table generated by contr.poly. This probably
applies equally to lm objects as well.

Dear statistics and R experts,
I am a new R-user and my statistics is probably more than a bit rusty. So
forgive me if the following question is relatively simple.
I would like to plot the predicted values from a quantile regression

You have a POSIXlt object, a list of length 9.

Hi,
I am trying to parse a date (that is read in as a factor) and add it
to a dataframe. The length of the parsed date is shorter than the
length of unparsed date and I therefore cannot add it to the dataframe:

Dear all,
I don't know what was the actual remedy, but after installing readline and
ncurses and then re-installing R, everything works fine (=calling the
commands history with the cursor keys).
I would like to thank for the help provided by Jason Turner, Philippe

R can use up to 2Gb, but Windows is unlikely to give you that much --
1.7Gb has been achieved (see the CHANGES file, I believe).

Asking the RWinEdt maintainer directly seems to be more appropriate than
asking on R-help.
There is no patch for the package RWinEdt available. Just the release
1.5-0 of that package.
