Do you mean like this:

Hello,
Try the following.
icol <- which(grepl("flag", names(mydf)))
mydf[icol] <- lapply(mydf[icol], function(x){
is.na(x) <- x == 0
x
})
mydf
# A A_flag B B_flag
#1 8 10 5 12
#2 7 NA 6 9
#3 10 1 2 NA
#4 1 NA 1 5
#5 5 2 0 NA
Hope this helps,

Previously, I took this table and finished my analysis in Excel using
Excel's "=if" function. However, I am sure it can be done in R. What I want
to do is set up a new data.frame with a new column for Accuracy Flags
(a_flag) as shown below.

[LLVMdev] how to track down a kernel miscompilation?
...volatile related. Now bugpoint has some
ways to run the code by some external agent which I haven't
investigated yet.
Oh and if you are trying to construct an entire kernel bitcode file,
the following rule will help:
cmd_ll_as = echo "module asm \"" > $@ ; $(ASMCC) $(a_flags) -c
-o - -S $< |perl -npe s/\"/\\\\22/g >> $@ ; echo "\"" >> $@

[LLVMdev] how to track down a kernel miscompilation?
Hi,
I am trying to build the Linux kernel with LLVM.
'ARCH=um' appears to work, now I am trying to get 'ARCH=x86' to work.
So far it seems there is something wrong with the boot vga code (it
finds no video modes), the acpi code, and the serial console code.
I am now trying to compile drivers/ with llvm-gcc and the rest with
gcc-4.2 (I have a wrapper script), I am compiling to

[RFC PATCH 00/33] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
