substitute, eval, quote and functions
Hi,
i am working with large data frames with many dependend variables. I
want to write some functions that will allow me to quickly select
variables from the frame and plot them in various colors depending on
factor columns, possibly selecting rows according to factor conditions.
In order to do this in a nice function, i need to understand how to work
with a column name in the body of a

Systemd and VirtualBox
The continuing challenges of getting a workable server continue.
The latest spins of VirtualBox seem to have solved the issues of DKMS
auto compiles of the driver being aborted. The yum updates work as
expected, provided one stops the running vms manually first.
However, trying to get systemd to start the vms is proving to be a PITA.
I have extensively googled and found that there are no

Caret train with glmnet give me Error "arguments imply differing number of rows"
Hello,
I'm training a set of data with Caret package using an elastic net (glmnet).
Most of the time train works ok, but when the data set grows in size I get
the following error:
Error en { :
task 1 failed - "arguments imply differing number of rows: 9, 10"
and several warnings like this one:
1: In eval(expr, envir, enclos) :
model fit failed for Resample01

matrix correlations with different packages
Dear all,
I'm calculating matrix correlations with permutation tests and I got this
funny result. All correlation coefficients are the same with mantel.test
{ncf} and pcol {simba} but the two functions yield dramatically different
p-values (using the same number of permutations). Could anyone please
enlighten me what is causing the difference and which result I can trust?

Problem with colors in contour plot
Dear R users,
I have a 51 by 51 matrix of p-values (named as pvalue_MA). I want to
present graphically this matrix in a plot (filled contour plot) where both
axes represent probabilities. I have also added a grid in this plot. I want
to highlight in white the cells of the grid that represent p-values smaller
than the (common) significance threshold, 0.05. The code from this plot is
colored in

survreg 3-way interaction

You have given us no data to diagnose your problem. What do you mean
by "cannot handle" -- does the package print a message "no 3 way
interactions", gives wrong answers, your laptop catches on fire when you
run it, ....?
Also, make sure you read
