--interactive and -f/-e
I was surprised by this:
R --interactive -e 'interactive()'
bash-3.2$ R -q -e 'interactive()' --interactive
> interactive()
[1] FALSE

as the command options document says that --interactive should force
interactive=TRUE:
" When *R* is run in a terminal (via |Rterm.exe| on Windows), it assumes
that it is interactive if ?stdin? is connected to a (pseudo-)terminal

problem with interaction in lmer even after creating an "interaction variable"
Dear all,
I have a problem with interactions in lmer. I have 2 factors (garden and
gebiet) which interact, plus one other variable (home), dataframe arr. When
I put:
/
lmer (biomass ~ home + garden:gebiet + ( 1|Block), data = arr)/
it writes:
/Error in lme4::lFormula(formula = biomass ~ home + garden:gebiet + (1 | :

R --interactive -e 'browser()'
I would like to have a mode where I can run some R code in an executable script, like with Rscript, but interactively, so that e.g. 'browser()' works.
From the manual page it looks like this should work:
R --interactive -e 'source("script.R")'
or we could shorten it to:
R --interactive -e 'browser()'
However, it seems that --interactive causes -e

main effect & interaction in 2-way ANOVA
Hi,
I am just a little confused of mian effect in the
analysis of variance (ANOVA) when you include or do
not include an interaction term. Let's assume a simple
case of 2-way ANOVA with 2 factors A and B, each with
2 levels. If it shows that main effect for A is
significant when the interaction between A and B is
NOT included, and the main effect for A is NOT
significant when the interaction

Model averaging with (and without) interaction terms
I?ve used logistic regression to create models to assess the effect of
3 variables on the presence or absence of a species, including the
interaction terms between variables and model averaging using MuMI:
model.avg
The top models (delta<4) include several models with interaction terms
and some models without; model weights are quite low for all models
(<0.25). My problem is that the models

Interaction plots (six on one page)
#Dear R users,
#I want six interaction plots to be on one page,

#My seccond question is, how I can reduce the empty space in the y-direction

r code to generate interaction columns
Hi,
is there a way to take a dataset and extract numeric columns and create interaction columns from it automatically?
For e.g. there are 5 columns of data: A,B,C,D,E.
CDE are numeric.
Can someone provide code to automatically create more columns such as:
1) C*D, C*E, C*D*E, (C+E)/(D+.01 (to avoid divide by zero), (D+E)/(C+.01 (to avoid divide by zero), (C+D)/(E+.01 (to avoid

Keyboard Interactive Attack?
I read an article today about keyboard interactive auth allowing bruteforcing.
I'm afraid I have minimal understanding of what keyboard-interactive really does. What does it do, and should I have my clients set it to off in sshd_config?

Bug in model.matrix.default for higher-order interaction encoding when specific model terms are missing
Hi,
I recently ran into an inconsistency in the way model.matrix.default
handles factor encoding for higher level interactions with categorical
variables when the full hierarchy of effects is not present. Depending on
which lower level interactions are specified, the factor encoding changes
for a higher level interaction. Consider the following minimal reproducible

interactions and stall or memory shortage
Hello,
After putting together interaction code that worked for a single pair of
interactions, when I try to evaluate two pairs of interactions(
flowers*gopher, flowers*rockiness) my computer runs out of memory, and the
larger desktop I use just doesn't go anywhere after about 20 minutes.
Is it really that big a calculation?

Command-line arguments and --interactive
Hello,
I am interested in passing a command or two to R on the command
line. The desired behavior is for R to run these commands first, and then
begin an interactive session. For example:
$ R -e 'foo <- read.csv("/tmp/foo.csv")'
...which would launch R and execute that command, so when I return from
getting coffee, foo would be loaded.
I know that if I put this command

Interpretation of high order interaction terms.
I have difficulties in interpreting high order interaction terms in
high-way ANOVA.
According to Introductory Statistics with R by Peter Dalgaard (Section 12.5),
"The exact definition of the interaction terms and the interpretation of their
associated regression coefficients can be elusive. Some peculiar things
happen if an interaction term is present but one or more of the main
effects are

Cross K Ripley's function and "spatio-temporal interaction power"
Dear All,
I have a collections of spatial data. I have to analyze pairs of these
point patterns to test their spatial interaction. I was moving towards
the cross K Ripley's function. The problem, however, are the following:
1) What is the best way to get a single real value that represents the
interaction "power"?
2) How to obtain a value that even allows me to rank the pairwise

Re. When is *interactive* data visualization useful to use?
Hello Tal,
You asked *When is it helpful to use interactive plots? Either for data exploration (for ourselves) and data presentation (for a "client")?*
My answer: It's helpful for checking data quality, for exploration with and without "clients", for checking results, and for data presenting.

python-interactive for CentOS/EL 4
Hi all,
Could anyone point me in the right direction for a package that
provides the 'interactive' module for Python? I need to do some SSH
stuff in Python so I grabbed python-paramiko from RPMForge (as always,
thanks Dag & co.). Paramiko appears to be dependent on python-crypto
but the RPM doesn't require it..
