When I run this over 1000 iterations, memory use ramps up to over 2.4 GB
While running it with 10 iterations uses far less memory,...

Possible with enableJIT function
...ge with the following small example.
<code>
library(nleqslv,lib.loc="../nleqslv.Rcheck")
library(pryr)
dslnex <- function(x) {
y <- numeric(2)
y[1] <- x[1]^2 + x[2]^2 - 2
y[2] <- exp(x[1]-1) + x[2]^3 - 2
y
}
xstart <- c(x1=1.5,x2=2)
nsims <- 10
for(test_iter in seq_len(nsims)){
z <- nleqslv(xstart,dslnex,jacobian=NULL)
print(paste("nleqslv iteration",test_iter,"and memory used is",mem_used()))
}
memory.profile()
gc()
print(paste("At end memory used is", mem_used()))
</code>
The final output is

How can I set the session in a functional test?
Hey :)
I need to simulate a login in my functional test, otherwise I can''t GET nor
POST to the action.
I need to set the session key "logged_in_user_id".
I tried this inside the setup() method:
session[''logged_in_user_id''] = 1
But that throws: TypeError: can''t convert String into Integer
Any ideas?
Thanks,
Rob

Writing a properly-formed custom type (configxml)
Please hold my hand.
After studying the wiki, several unofficial pages, various mailing list entries, and the operation of the "iptables" type as found on the net, I have created a custom type, lovingly named ``configxml''''.
It updates attributes on the first element matching a supplied XPath in a given XML file. The first use case is configuring Atlassian JIRA to use
