Colapsar una matriz con NA en una única fila
Javier
Muchas gracias por su respuesta
Aunque no está funcionando, pues si ejecuto:
EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var1),] obtengo Var1, Var2,
Var3,...Varn con datos "texto", NA, NA....NA
Pero al ejecutar
EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var2),] obtengo Var1, Var2,
Var3,...Varn con datos NA,"texto", NA....NA
Estoy tratando de dar la vuelta con el loop

Colapsar una matriz con NA en una única fila
Hola
Consulto por un problema que no consigo resolver.
Tengo un dataframe con muchas columnas todas de texto. Cada columna tiene
solamente un valor válido y el resto son NAs. También cada fila tiene un
único valor válido. Quiero colapsar ese data frame en uno que tenga
solamente una fila y todas las columnas. Intenté con loops, while, apply y
otros parecidos pero no lo logro

Newbie: Ranking a data frame, grouped by 2 or more columns
Hi,
I'd like to rank obs in a data frame as subset by 2 or more columns...
The example input would look like the following:
====+====+====+====+
x y v
-- -- --
a w 200
a w 100
b w 500
b w 200
b z 300
b z 400
====+====+====+====+
And the data frame I want to create is below:
====+====+====+====+
x y v rank
-- -- -- ----
a w 200 1
a w 100 2

group bunch of lines in a data.frame, an additional requirement
Thanks for pointing me out "aggregate", that works fine!
There is one complication though: I have mixed types (numerical and character),
So the matrix is of the form:
A 1.0 200 ID1
A 3.0 800 ID1
A 2.0 200 ID1
B 0.5 20 ID2
B 0.9 50 ID2
C 5.0 70 ID1
One letter always has the same ID but one ID can be shared by many
letters (like ID1)
I just want to keep track of the ID, and get

Removing constants from a data frame
Suppose I have
x<-data.frame(v1=1:4, v2=c(2,4,NA,7), v3=rep(1,4),
v4=LETTERS[1:4],v5=rep('Z',4))
or a much larger frame, and I wish to test for and remove the constant
numeric columns.
I made:
is.constant<-function(x){identical(min(x),max(x))}
and
apply(x,2,is.constant) # Works for numerics
x[,-which(apply(x,2,is.constant))]
I'd really like to be able to

Group by
I have a matrix with a POSIXct as a numeric in the first column.
I would like to create a new matrix that is "grouped by" my chosed time

i.e. So I would like to group by hour or day or 5 days, and have all my
columns be summed or averaged or counted..

Windows 2003 Active Directory and Group Access
Hi together,
we have a Windows 2003 Active Directory Server, working together with Samba Version 3.0.2a-Debian. It seems
everything (Kerberos authentication and so on) works fine. All the authentication is done by the windows 2003
server. My problem is, that I can't connect to a share via a windows xp client, when the share has an option
"valid user" which defines a group of the

Change axes labels in Lattice
Hello
I'm making a levelplot with frequencies in a 2*2 table with ordered factors. I get the plot I want, but axes draw the levels of the factor (1,2,3,4..) instead of
the desired labels.
Is there a way to alter this axes labels in lattice graphics?
Thanks for the reply

column-wise z-scores by group
Hi,
I have a dataset of historical monthly temperature data that is grouped by
weather station. I want to create z-scores of the monthly data using a base
period of a subset of years. I subset the dataset first to include only data
from the years (V2) that make up the base period so I could calculate the
appropriate means and standard deviations

AD group member troubles
Hidiho!
I have a win2k network with AD and some samba servers. About 1.5 months
ago suddenly one user could not access any files on any samba server (no
probs on the win2k servers). A few days ago a second user couldn't
access anymore any files on any samba server. Both can access files only
if the user has access rights but if only a group (where the user is a
member of) is granted

using read.table, removing extra quotation mark from a text field? (e.g. ""cat" )
I am using read.table to import a text file within R.
There are several "errors" in my text file. An "extra" quotation mark has
inadvertently been included within a few text fields.
e.g. for a pipe (|) delimited text file, I have something similar to this:
1|7|30| "dog"
2|6|25| ""cat"
3|4|20|""
4|5| 56| "mouse"

data management
Dear Rxperts,
I have a varaibles data file that looks like this
p(1) 10
p(1) 3
p(1) 4
p(2) 20
p(2) 30
p(2) 40
p(3) 4
p(3) 1
p(1) 2
I cannot process these data with R because it does not like the parentheses.
How can I get these to look like:
p1 10
p1 3
p1 4
p2 20
p2 30
p2 40
p3 4
p3 1
p3 2
The data is in a tab delimited text file and I want to get it into a
data.frame().
Many thanks in

Automatic provider API loader for mapstraction?

today I gave a talk at Barcamp Vienna (
http://www.barcamp.at/BarCamp_Vienna_Juni_2009) about Mapstraction and its
recent progress.
The crowd was really impressed! In the follow-up discussion several people
were asking why mapstraction itself can''t take care of loading the provider
APIs.
I''m not sure if anybody is working on this, but such an automatic api loader

How to extract rows from data frame based on unique variable groupings
R community,
I would like to know how to extract rows from a data frame (DF) such that
each row in the new data frame (D.F) represents the first instance of
a unique variable pairing in the original dataframe (ordered first by
variable V1 then by variable V2). The unique function does not seem
to be able to accomplish this. I imagine there must be a simple solution for this,

[PATCH v7 0/5] replace hwmon_device_register for hwmon_device_register_with_info
This v7 fixes removes dummy functions which only had a return and moves the code
into the switch statements.
Versions:

* Keep temp attrs as read only
v2 -> v3:
* Code fix-ups: struct and string as const and add return within switch
due to fallthrough
* Add Signed-off-by to all commits
v3 -> v4:
* Rever const to struct attribute. Kbuild
