naming of columns in R dataframe consisting of mixed data (alphanumeric and numeric)
Hello,
I have an r function that creates the following dataframe tresults2.
Notice that column 1 does not have a column heading.
Tresults2:
[,1]
estparam 18.00000
nullval 20.00000
. . .
ciWidth 2.04622
HalfInterval 1.02311
pertinent code:
results<-cbind( estparam, nullval, t, pv_left, pv_right, pv_two_t,
estse, df, cc, tbox, llim,...

Nonlinear statistical modeling -- a comparison of R and AD Model Builder
...the present day version of R so that
R can now be directly compared with AD Model Builder for this type of model.
I have put the results of the test together with the original
Schnute and Richards paper and the working R and AD Model Builder
codes on Otter's web site
http://otter-rsch.ca/tresults.htm
The results are that AD Model builder is roughly 1000 times faster than
R for this problem. ADMB takes about 2 seconds to converge while
R takes over 90 minutes.
This is a simple toy example. Real fisheries models are often hundred of
times more computationally intensive as this one....

Calculating the t-test for each row
Hi Everyone,
I need some simple help.
Here are my codes
##########will give me 10000 probesets####################
data.sub = data.matrix[order(variableprobe,decreasing=TRUE),][1:10000,]
dim(data.sub)
data_output<-write.table(data.sub, file = "c://data_output.csv", sep = ",",
col.names = NA)
When i export to excel, it shows me this. This is just a short version.

[LLVMdev] problem trying to write an LLVM register-allocation pass
I have a new problem: Register RBP is used in a function foo. (I am not
allocating RBP to any virtual register, the instances of RBP in function
foo are in the machine code when my register allocator starts.)
Function foo calls function bar. Register RBP is not saved across the
call, though it is live after the call. Function bar includes a virtual
register. The code that I'm using to
