applying a loop to multiple dataframes
Hello again R-folks,
I'm trying to apply a loop to multiple data frames and then organize the data in a manageable form. I have the code for my loop figured out (thanks to help from this list)...it runs up to 2000 iterations of a "while" loop until it finds a 40-row "d2p" column sum >5
n<-nrow(dsub.f1)
test<-0
for(k in 1:2001){
	if(k>2000){
	break}  #stops

[LLVMdev] llvm-c: LLVMCreateExecutionEngine returning empty error message
Hello, I'm using the llvm-c bindings for C, but I'm getting some problems,
the LLVMCreateExecutionEngine is returning 1 but the error message is an
empty string (it's !=NULL).
The steps I'm doing is to create the module, then I call LLVMVerifyModule to
verify and it works fine, later I call
LLVMCreateModuleProviderForExistingModule and it returns !=NULL MP, so it's
ok, but

gam (mgcv) problem: Error in while (mean(ldxx/(ldxx + ldss)) > 0.4) { :, missing value where TRUE/FALSE needed
Hi All,
I'm running into a problem with GAM (in the MGCV package).  When I try 
to estimate the model, I get the following error message:

[PATCH nbdkit 1/3] include: Function indirection for PE DLL
From: Yifan Gu <gyf304@gmail.com>
This patch adds in indirection for API functions, as PE DLL loader
does not resolve undefined symbols.
This patch only includes header changes.

dovecot-2.1-pigeonhole-0.3.0 identifier redeclared: sieve_multiscript_run (patch)
Hi,
I recently compiled dovecot-2.1.1 on Solaris 10 with Sun Studio, but
when I want to compile Sieve for this version
(dovecot-2.1-pigeonhole-0.3.0) I get an error:
"sieve.c", line 578: identifier redeclared: sieve_multiscript_run
and I see that declaration in sieve.h is different from definition in
sieve.c, so compilation process fails with SunStudio cc compiler.

Bayesian mixing model
Fellow R users,
I'm using the BCE {BCE} function to run a Bayesian sediment mixing model. The aim is to find the optimum % contribution from each of the 4 source areas that can yield the target geochemistry.
I have geochemistry for 4 source areas called Rat:
Rat<-read.table(text="CaO       MgO      Na2O    Al2O3

[PATCH nbdkit 2/3] server: Inject API functions for Windows
From: Yifan Gu <gyf304@gmail.com>
Windows PE DLL needs function indirection, this patch injects API
functions for plugins / filters if on Windows.
Note that nbdkit_peer_name is explicitly disabled due to potential ABI
incompatibilities.

extracting F, df and r squared using "sapply"?
Hi, All
How does one remove relevant information from a regression output besides 
just the coefficients?
I've been able to modify the example given under "help(by)" to give me some 
additional information, but not everything I need.
If you adjust the call statement from what is listed by adding the summary 
statement like so:
tmp <- by(warpbreaks, tension, function(x)

A quick question about lm()
I have a simple regression using lm().
If I just want to check the coefficient, I can use summary(lm())$coef; if I
need the standard error, I can use summary(lm())$s, if I need the residuals,
I can use summary(lm())$res.  OK.  How can I get the R-squares and Adjusted
R-squares using $...?
Is there a function, like objects(), that can show all the references for
values?
Thanks a lot!

[LLVMdev] running clang format on the Mips target
Hi David,
I agree with you that it would be rude to simply clang-format the MIPS backend without coordination with any out-of-tree derivatives. To be honest, it hadn't occurred to me that there would be any such derivatives and the possibility wasn't raised in our internal discussion before we brought the subject up on this list. I'm keen to coordinate with such derivatives to
