TAB
Hello,
I am new on the list and in R language. I only have one question -
could it be achieved that pressing a TAB key autocompletes
the possible directions to the R language. This is a Unix
feature and it would greatly boost the performance.
I have R-1.3.1 installed on Linux.

CentOS 7.x Russian certification
Dear all,
does anyone have any idea where to get a list of all CentOS 7.x versions
that are certified to be used within Russia.
My guess is that organizations, such as FSTEK, TR-CU declares those
versions/distributions of CentOS that are certified to be used with
commercial projects in Russia.
Anyone with some information on this, plase advice, I would be very
grateful.
Regards,
Gorazd

How can I make has_many prevent a delete that would lead to orphans?
e.g.
class Asset < ActiveRecord::Base
validates_presence_of :asset_number, :make, :model, :location,
:name, :serial_number
validates_numericality_of :asset_number
validates_uniqueness_of :asset_number
belongs_to :user
belongs_to :location
belongs_to :asset_type, :foreign_key => ''type_id''
end
class Location < ActiveRecord::Base
validates_presence_of :name

Sorting by two fields
I have a list of TimeSheet objects from an ealier AR query, which I
can sort by the full name of the user like so:
@time_sheet_entries.sort! { |a,b| a.user.full_name <=> b.user.full_name }
I can sort by the started time like so:
@time_sheet_entries.sort! { |a,b| a.start_time <=> b.start_time }
My question is how do I do a sort so that the list is sorted primarily
by user.full_name

Basic question on applying a function to each row of a dataframe
Hi,
I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x
& w, as follows :
x w
1 1 1
2 2 1
3 3 1
4 4 1
etc
I would like to apply the function foo to each 'pair' within DF e.g
foo(1,1), foo(2,1), foo(3,1) etc
I have tried
>apply(DF,foo)
>apply(DF[,],foo)
>apply(DF[DF$x,DF$w],foo)
However, none of the above worked. Can anyone help ?

How can I create OrderItems that go in a Order?
I suspect my problem is similar to having an order and wanting to have
order items as part of the order, so I''ll explain the problem in those
more familiar terms and then explain what if anything makes my actual
situation different at the end.
In an Order lets say you have: shipping_address and a shipped bool.
OrderItem has quantity and name
So Order has_many :OrderItems, and OrderItem

Stupid question: where is the Preferences box?
Good day!
I am GUI-challenged, and proud of it, but I would like a bit of help.
When I start netscape (picked from an Earthlink CD) it raises a message
box that says (this is picked from --debugmsg +text and folded for
mailing convenience):
trace:text:DrawTextExW L"Error: temporary directory E: does not exist.
Please enter a new directory in the preferences box.", 99 ,

Log entries with truncated service names
Hi,
Situation:
I'm seeing lots (~500k per day) of log entries like:
smbd[13939]: itlab-pc06 (::ffff:10.51.51.103) couldn't find service it261
In this case, the last character of the request is truncated - it should be
it2610
I'm seeing the same/similar issue to

Rpart question - labeling nodes with something not in x$frame
I have a tree created with
tr.hh.logcas <- rpart(log(YCASSX + 1)~AGE+DRUGUSEY+SEX+OBSXNUM +WINDLE,
xval = 10)
I would like to label the nodes with YCASSX rather than log(YCASSX +
1). But the help file for text in library rpart says that you can only
use labels that are part of x$frame, which YCASSX is not.
Is there a way to do what I want?
Thanks in advance

Thanks to everyone who replied to my first problem. Here is the second one:
Is the function "lme" (Mixed Model) also in a foreign library(shouldnt, as
this is a basic statistical function)? I am trying to use lme in R and it
replies that it couldnt find the function lme...weird...
Thanks for replying!
