making object.size() more meaningful on environments?
Hi,
Currently object.size() is not very useful on environments as it always
returns 56 bytes, no matter how big the environment is:
env1 <- new.env()
object.size(env1) # 56 bytes
env2 <- new.env(hash=TRUE, size=75000000L)
object.size(env2) # 56 bytes
env3 <- list2env(list(a=runif(25000000), L=LETTERS))
object.size(env3) # 56 bytes
This makes it pretty useless on

plot points using vis.gam
Hello,
I'm trying to illustrate the relationships between various trait and
environment data gathered from a number of sites. I've created a GAM to do
this: gam1=gam(trait~s(env1)+s(env2)+te(env1,env2)) and I know how to create
a 3D plot using vis.gam. I want to be able to show points on the 3D plot
indicating the sites that the data came from. I can do this on a 2D plot
when there is one

Yes, but that's still a *much*

Geppetto complains about uninitialized variables in reduce function
Hello,
I''m using the following expression to format a list:
$valid_environments = [''env1'', ''env2'', ''env3'']
$env_message = $valid_environments.reduce |$message, $env| {
"${message}, ${env}" }
It works at run-time (Puppet 3.2.4 standalone with "--parser=future").

Add Anova statistics in each figure
Hi R Users,
I created interaction plots in ggplot2 and was trying to add output of two way ANOVA models, especially only interaction ( example treatment*control F(XX, XX) = xxx, p = xxx) into figures, but i was not able to add. Would you mind to help on how I can add information into each figure? I have attached the example data and the code that I used for this.

partial mantel tests in ecodist with intential NA values.
I would like to perform partial mantel tests on only within group values, with "between group" values assigned to NA.
This is possible in package ncf partial.mantel.test, however this sues a different permutation to that used in ecodist.ecodist will not accept data with NA values, returning a "matrix is not square error.
is it possible to perform this test in ecodist?
many thanks

Conditional CCA and Monte Carlo - Help!
Hi All,
I am using canonical correspondence analysis to compare a community
composition matrix to a matrix of sample spatial relationships and
environmental variables. In order to parse out how much variance is
explained purely by space (S/E) or the environment (E/S) I am using a
conditional (partial) CCA. I want to test significance via Monte Carlo but
I can not find a way to do this with a

making object.size() more meaningful on environments?
Herve,
The problem then would be that for A a refClass whose fields take up N
bytes (in the sense that you mean), if we do
B <- A
A and B would look like the BOTH take up N bytes, for a total of 2N,
whereas AFAIK R would only be using ~ N + 2*56 bytes, right?

numericDeriv alters result of eval in R 4.0.1
Dear R developers,
I've run into a weird behavior of the numericDeriv function (from the stats
package) which I also posted on StackOverflow (question has same title as
this email, except for the version of R).
Running the code bellow we can see that the numericDeriv function gives an
error as the derivative of x^a wrt a is x^a * log(x) and log is not defined
for negative numbers. However,

nlme, MASS and geoRglm for spatial autocorrelation?
Hi.
I'm trying to perform what should be a reasonably basic analysis of some
spatial presence/absence data but am somewhat overwhelmed by the options
available and could do with a helpful pointer. My researches so far
indicate that if my data were normal, I would simply use gls() (in nlme)
and one of the various corSpatial functions (eg. corSpher() to be
analagous to similar analysis in SAS)

[External] numericDeriv alters result of eval in R 4.0.1
Dear all
As far as I could trace, looking at the function C function numeric_deriv,
this unwanted behavior comes from the inner most loop in, at the very end
of the function,
for(i = 0, start = 0; i < LENGTH(theta); i++) {
for(j = 0; j < LENGTH(VECTOR_ELT(pars, i)); j++, start += LENGTH(ans)) {
SEXP ans_del;
double origPar, xx, delta;
origPar = REAL(VECTOR_ELT(pars, i))[j];

Functions within functions - environments
Dear list,
I have a problem with nested functions and I don't manage to get it
solved. I know I should be looking in environments, and I have tried a
lot, but it keeps on erroring.
An easy version of the problem is as follows:
innerfunction<-function()
{
print(paste(a, " from inner function"))
print(paste(b, " from inner function"))
setwd(wd)
}

Environments and parallel processing
While using parallelization R seems to clone all environments (that are normally passed by reference) that are returned from a child process. In particular, consider the following example:
library(parallel)
env1 <- new.env()
envs2 <- lapply(1:4, function(x) env1)
cl<-makeCluster(2, type="FORK")
envs3 <- parLapply(cl, 1:4, function(x) env1)
envs4 <- parLapply(cl, 1:4,

Re-attaching a package environment drops the attributes
Hi.
contrary to other environments, the attributes of a *package*
environment are dropped (from the new environment) when attach():ing
it to the search() path. This might or might not be surprising, but
have some side effects if rearranging/attaching package environments.
# Example - Regular environments
env <- new.env()
attr(env, "foo") <- "bar"
print(env)

Puzzling... puzzling... puzzling...
Hi all,
I made sure that it's "env$sRes1$nPositionsOptimizedM" that's correct...
not the "env$sRes1$nPositionsOptimized"...
But it seems both point to the same memory area...
This is very dangerous because I have used naming conventions such as:
MyLongVariableNameForA
MyLongVariableNameForB
MyLongVariableNameForC
...
...
Then if internally they are actually the

Unable to fit model using “lrm.fit”
Hi,
I am running a logistic regression model using lrm library and I get the
following error when I run the command:
mod1 <- lrm(death ~ factor(score), x=T, y=T, data = env1)
Unable to fit model using ?lrm.fit?
where score is a numeric variable from 0 to 6.
LRM executes fine for the following commands:
