Date on x-axis of xyplot
xyplot doesn't seem to want to label my x-axis with dates but instead puts
the day-number for each date.
begdate is the number of days since January 1, 1960 and was initially
created by
library(date)
...
polls$begdate<-mdy.date(begmm,begdd,begyy)
I create a new dataframe (pollstack) which includes begdate. In the process
begdate seems to lose its date attribute so I redo it as:

non-intuitive behaviour after type conversion
Deal list,
I have a data frame (birth) with mixed variables (numeric and
alphanumeric). One variable "t1stvisit" was originally coded as
numeric with values 1,2, and 3. After attaching the data frame, this
is what I see when I use str(t1stvisit)
$ t1stvisit: int 1 1 1 1 1 1 1 1 2 2 ...
This is as expected.
I then convert t1stvisit to a factor and to avoid creating a second

warning for inefficiently compressed datasets
Hi,
Recently added to doc/NEWS.Rd:
'R CMD check' now gives a warning rather than a note if it finds
inefficiently compressed datasets. With 'bzip2' and 'xz' compression
having been available since R 2.10.0, there is no excuse for not
using them.
Why isn't a note enough for this?
Generally speaking, warnings are for things that are dangerous,
or unsafe,

stacking consecutive columns
I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964).

transformar una variable de tipo carácter
Buenos días
No sé qué función tengo que utilizar para cortar una variable cadena. Veamos a ver, teno la variable MUNICIPIO que recoge la siguiente información: 26001-Ábalos y necesito crear la variable COD_MUNICIPIO cuyo valor ha de ser 26001.
Gracias

Cortar una cadena por un caracter solo cuando no forma parte de una subcadena entrecomillada
Hola, ¿qué tal?
Tengo el siguiente problema. Me llegan (simplificando) cadenas del tipo
1,2,"algo"; 3,"cosa"; 4,2,3,7;
y tengo que partirlas por el caracter ";" para meterlas en una lista.
Lo hago con strsplit y no tengo problemas...
... hasta que recibo cadenas como
1,2,"algo;todo"; 3,"cosa"; 4,2,3,7;
en las que existen puntos y coma

un solo un favor
Hola a todos
Esta es mi primera pregunta en el grupo, y es sencilla pero me tiene
atascado. Estoy tratando de cortar mi mapa de (poner limites en UTM) en un

creo no estar usando bien la función CRS ponendo bien los limites
requeridos.

protect rule prevents file sending when in merge filter file?
Hi,
We upgraded from rsync 2.6.8 to 3.0.6, and ran into a problem with P (protect)
rules coming in from filter files. The rule works if given on command line, but
if given via . (merge), it no longer works. The effect is that files are not
sent to the destination any more.
I verified the problem still exists in 3.0.9pre2. I don't think this is bug

Need to abstract changing name of column within loop
Hi,
I'm struggling to figure out the way to change the name of a column
from within a loop. The problem is I can't refer to the object by its
actual variable name, since that will change each time through the
loop. My xts object is A.
> head(A)
A.Open A.High A.Low A.Close A.Volume A.Adjusted A.Adjusted.1

Summary functions to dataframe
I have written a few different summary functions. I want to calculate
the statistics by groups and I am having trouble getting the output as a
dataframe. I have attached one example with a small dataset that
calculates summary stats and percentiles, I have others that calculate
upper confidence limits etc. I would like the output to be converted to
a dataframe with one of the columns as the

Contar categorías después de ciertos valores
Hola,
Estoy intentando averiguar cómo contar el número de categorías situadas después de ciertos valores. Por ejemplo, en el siguiente vector:
x <- c(3, "A", "B", 5, "A", 4, 5, "A", "A", 3)
el resultado que quisiera obtener es:
Valor -> Resultado
3 -> 1 A y 1 B
4 -> 0 A y 0 B
5 -> 3 A y 0 B

sobre fread {data.table}
Hola, M. Luz.
Hay infinidad de motivos por los que se te puede cortar la lectura de un archivo de datos, pero los más habituales son encontrar un "#" o unas "" en los registros, o una línea toda en blanco.
Lo primero yo creo que es dejar el archivo en texto plano (lo que te recomendaba Carlos de usar el original, no el docx), y buscar esos caracteres con un editor de texto

También si nos envías el .rel nos ayudaría a ver qué pasa...

plotting moving range control chart
I have been having the same problem as poster Hodgess, below. It appears
that her question was never answered, so I would like to share a solution
with the community.
The problem is the (apparent?) inability to produce moving range process
behavior (a.k.a. "control") charts with individuals data in the package
"qcc" (v. 2.0). I have also struggled with the same limitation in
