Viewing specific data from a dataframe
Dear R users,
Simple question. Can anyone help with the code that would allow me to view only the variables who's correlation output is >0.8?
This is the code I'm using to date

Kind regards

extension to nlme self start SSmicmen?
Dear list,
Has anyone created a version of SSmicmen that allows testing for group
differences? The basic Michaelis-Menten equation is:
(Bmax * X) / (Kd + X).
The nlme package allows modeling of random effects for Bmax and Kd as
needed, but I curious how I can build in group differences? I have
receptor binding data for strains of mice, and following Pinheiro and

logrotate, mongrel cluster and monit
While I could figure this out, I''m asking here first to see if anyone
has already dealt with/created this. I''m running a mongrel cluster,
running 4 mongrels on ports 8001-4. I''m using capistrano to deploy.
And I''d like to use monit to check to make sure everything is running
nice.
I''d like to have monit restart only single mongrels if they fail, and

Dear Kornad,
I think I have started to understand what you try to achieve. The problem is to fit a NLE and compute the parameters of the NL-Eq. I have included the R Help-list back in the loop, as I am not an expert in optimization.

Interaction term in multiple regression
Hello All, Thank you for taking my question. I am looking for
information on how R handles interaction terms in a multiple regression
using the ?lm? command. I originally noticed something was unusual
when my R output did not match the output from JMP for an identical
test run previously. Both programs give identical results for the main
test and if the models do not contain the interaction

Fw: Calling a LAPACK subroutine from R
Sorry for cross-posting, but I realized my question might be more appropriate for r-devel...

Fw: Calling a LAPACK subroutine from R
Berend,
I do not think this works with gfortran 7+. I am calling the BLAS
subroutine dgemv from Fortran code in my package eha, and the check

mutual information for two time series
Hi I hope this is going to the right place. I am trying to write a program
which uses KernSmooth library to estimate mutual information between two
time series at various different lags. At the moment it’s producing negative
values, which is supposed to be impossible (something is fishy). I am
summing across one row of the matrix to get p(value is in bin x) and summing
across the columns to get

WinDbg?
Hello,
I have been struggling with WinDbg/Kd for the last week, but to no avail... So I finally decided to ask here.
Basically, I am using a Windows XP virtual machine (thanks to VMWare6) and wanted to do some kernel debugging using Windbg. So, I did configure everything from the virtual machine side (using this guide: http://silverstr.ufies.org/lotr0/windbg-vmware.html), and then tried my hands

one-site competition data // curve fitting
Hello everyone,
I have biological data from a competition experiment where a free ligand is titrated against the binding of a protein.
Now, I would like to fit a standard on-site binding curve to this data in order to obtain the IC50 and Kd values.
Unfortunately I have not been able to find a package/function which allows such a fitting and calculates the results.
Does anyone know if there is

truly object oriented programming in R
Good morning! I recently implemented a KD tree in JAVA for faster
kernel density estimation (part of the code follows). It went well. To
hook it with R, however, has proved more difficult. My question is: is
it possible to implement the algorithm in R? My impression seems to
indicate no as the code requires a complete class-object framework that
R does not support. But is there an R package or

Calling a LAPACK subroutine from R
Followup:
I have checked my package nleqslv which uses dgemv only from Fortran, on Kubuntu 18.04 with the development version of R.
No errors or problems.

Yes, I know how to do that, but I find it somewhat bizarre that it is
impossible to call a Fortran subroutine from Fortran. And rewriting
'dgemv' was simple:

Need help
Hello,
I am brand new in this site as well as in R. Please accept my early apology if it's not the right place to ask such a question.
I have the following equation:
b=[2(1-a)(1+2a)^0.5]/(1+3a)
How can I solve the above equation for 'a' using R?
Thanks in advance.

predict.loess() segfaults for large n?
Hi,
I am segfaulting when using predict.loess() (checked with r62092).
I've traced the source with the help of valgrind (output pasted
below) and it appears that this is due to int overflow when
allocating an int work array in loess_workspace():
liv = 50 + ((int)pow((double)2, (double)D) + 4) * nvmax + 2 * N;
where liv is an (global) int. For D=1 (one x variable), this
overflows at
