Sort a column in a dataframe
Dear Users
This is my dataset called mydata4. I want to sort the dataframe on the first
column PxMid which is basically a column with dates.
I've tried mydata4<-mydata4[order(mydata4$PxMid),] but it doesnt work. Could
it be because these are dates?
Please help I'm really stuck !!
Thank you for your time.
Regards

RFC: Lazy syntax for paragraphs, blockquotes and lists

it was requested that kramdown (a Markdown parser in Ruby, see

So I sat down, thought about it, skimmed through the Markdown ML on
issues regarding lazy indentation as done with Markdown and now I have
some rough idea on how to do this in kramdown.

Kernel crash with acpi_processor, cpu_idle and intel_idle =y
Hi everyone,
When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE
to y then I cannot boot Xen; there is a crash. If I turn
CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has
booted, xenpm works and gives some sane output, see below. I have
tested this with kernels 3.2 to 3.4.6.
Is it impossible to use INTEL_IDLE with Xen? If this is a known issue
then maybe
