Win2k oplocks and you
Hello list!
I've seen the threads in this months archives on oplock issues, so I
hope I am not hitting a sore spot by bringing it up again. The reason I
am beating on this is that I've got a testable, repeatable issue with
Win2K terminal server (SP2) running CorelDRAW 10 (patched to current)
against a Debian Woody box running Samba 2.2.3a-6 for Debian. Since I

long character string problem
Hi All
I am having 2 very long character strings (550chars) and I want to put them as
expressions together with c(). The problem is that I also get these
double-quotes, as seen below in 'fct'. How can I remove these double-quotes? I
tried as.name() but it did not work (because of size?). These are creating
trouble with subsequent programs, which I tested with strings that for some

[LLVMdev] ScheduleDAGInstrs computes deps using IR Values that may be invalid
Hi All,
I've encountered an issue where tail merging MIs is causing a problem with
the post-RA MI scheduler dependency analysis and I'm not sure of the best
way to address the problem.
In my case, the branch folding pass (lib/CodeGen/BranchFolding.cpp) is
merging common code from BB#14 and BB#15 into BB#16. It's clear that
there are 4 common instructions (marked with an *) in BB#14

stepwise regression
Dear all,
I have encountered a problem when perform stepwise regression.
The dataset have more 9 independent variables, but 7 observation.
In R, before performing stepwise, a lm object should be given.
fm <- lm(y ~ X1 + X2 + X3 + X11 + X22 + X33 + X12 + X13 + X23)
However, summary(fm) will give:
Residual standard error: NaN on 0 degrees of freedom
Multiple R-Squared: 1, Adjusted

How to change the order of columns in a data frame?
Dear all,
I have a data frame in which the columns need to be ordered. The first column X is at the right position, but the remaining columns X1-Xn should be ordered like this: X1, X2, X3 etc instead of like below.

Hi Milu,
byapply(df, 12, function(x) apply(x, 1, max))
You might also be interested in the matrixStats package.

I am new to more radical programming in R. I am trying to write a nested 'for' loop to produce output that takes subscripts like:

I want to output for a computation using the combination values of i and j a value x like this;
