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.

recursive finds
I am trying to supplement and ultimately provide a patch for ''foreman'' which is an adjunct to puppet.
Essentially, there is a Hosts class which belongs_to Hostgroup and Hostgroup class has a column called ''ancestry'' which is actually a Hostgroup (probably what is referred to as STI but I am not sure) and thus within Foreman, nesting Hostgroups is not uncommon.

(no subject)
Hi
I need an advise if any one can help me.
i have mass of data in 2 array A and B:
A = 0 1 0 0 1 1 0 0
B = 0 0 0 1 0 1 1 1
and i have 3 rules to merge them into 3rd array C:
if A[i] + B[i] == 0 then C[i]=0
if A[i] + B[i] == 1 then C[i]=1
if A[i] + B[i] == 2 then C[i]=2
it looks easy but with the regular way (loop) with large data it takes days (i test it).
If any one can advise me what to do

C API - no NULL pointer guarantee?
Erez,
I think the API is very explicit about this, NULL is not an accepted input for any function taking SEXP by design. The special case of try*Eval() return values can be taken as a case where the resulting object is not actually SEXP but rather a special type which can be NULL (=failure) or SEXP. It may be even perhaps useful to declare it as a separate type to make this clearer, but I

Conditions for using Speex
Hello Speex.
We are a small Canadian company currently researching the possibility of
using Speex for an iPhone application.
We wonder if Speex can be used to develop paid applications and if you
require any fees or other payments if it used commercially
Thank you.

C API - no NULL pointer guarantee?
Thank you Ivan,
At this point, without it being documented explicitly, I tend to lean on the safe side.
If the non-null assumption is ever incorrect, on debug and safe builds unwrapping is an assert that will guarantee to crash R.
While the source code has plenty of NULL checks, also for some SEXP, it's hard to tell just from grepping if any are related to the public API or not.

journal buffer_credits problem
Hi, we're working on a stackable versioning file system for 2.4.x.
Versioning can easily create lots of files for a file that gets modified
frequently, and our current design puts all versions of a file in the same
directory as the main file. We are therefore evaluating how stable and
efficient different combinations of file systems would be in this scenario.
We've run our versionfs on

Route by destination port?
Hello all,
We have two ADSL lines configured on a single box, hence interfaces ppp0 & ppp1.
Is there a way to route packets to ppp0, say based on destination port
80 & other traffic like voice through ppp1?
Thanks.

Graphic boot ...
Hi Peter and Group,
First, thanks for great boot system.
My goal is to create a boot process that is clean from any text
message and shows simple graphics at startup.
That graphic image will last until the X server is starting (with the
same background, might be with different resolution).
My reason is, that many end users prefer graphics on simple cryptic
text messages.

[PATCH] v2v: rhv plugin - fix DC search string
Search for DC by 'storage.name=' to make it explicit.
I.e. "storage=" uses regex, so similar names can be
found in the search query. For example, searching for
a domain named FCSD, will find FCSD1 as well.
