imap-login hangs after receiving revoked SSL certificate
Good time of the day!
My English is not very good, excuse me if I said something wrong.
I use dovecot-2.1.16 on Gentoo Linux amd64.
I need to setup dovecot (imap and pop3) for SSL and non-SSL connection
simultaneously. For SSL connections client must submit a valid SSL
certificate. Now SSL part of dovecot.conf looks like this:

ssl = yes

Different settings for SSL/non-SSL protocols
Good time of the day!
It is possible to setup dovecot with different requirements for SSL and
non-SSL protocols?
What would I like to do:
pop3/imap non-SSL = allowed plain text authentication.
pop3/imap with SSL = allowed plain text authentication with required
valid SSL certificates.
I need to allow access from any IP address for first group of users,
which have valid SSL certificates. And

summary statistics
below is my data frame. I would like to compute summary statistics
for mgl for each river mile (mean, median, mode). My apologies in
advance- I would like to get something like the SAS print out of PROC
Univariate. I have performed an ANOVA and a tukey LSD and I would
just like the summary statistics.
thanks

Running GTA Classics.
After downloading the first two Grand Theft Auto games from the Rockstar Classics website, and installing the first game I received this error:
> MGL Fatal Error!
> Error 268.473
> Cannot find a suitable display mode.
After a bit of searching, I believe that this is a problem with running the game under Wine, and not with my PC. Then, although I probably should have checked first, I

Adding ScreenDC
Here is the file to add ScreenDC. I noticed that it inherits from wxDC
which is what the docs show but the headers for each platform are much
different:
- Mac,MSW,os2,motif,palmos all inherit from wxWindowDC
- X11,GTK inherit from wxPaintDC
- MGL, cocoa inherit from wxDC
After saying that on Windows it still work inheriting from wxDC so I
left it for now, any thoughts?

Mocking to spec a sort_by method
Hello,
I have a question regarding the use of Mocha with rSpec to spec one of
my methods.
My spec contains the following
vehical1 = mock()

vehical1.stubs(:mph).returns(150)
vehical2.stubs(:mph).returns(250)
comparer.add_vehical([@vehical1, @vehical2])

The comparer is an object that has a basic "stack like" functionality,

Gracias por el consejo. Aparentemente no lo estoy aplicando bien, pues el
objeto que obtengo no contiene lo que quiero.
Me explico, al ejecutar
txt <- vector('list', length = length(names)) #names el el vector donde ya
tenía almacenada la lista de txt's
for(i in seq_along(txt)){
txt[[i]] <- Corpus(VectorSource(names[i]))
}
obtengo el objeto txt:

data format issue
Dear all-
I have a dataset (see a sample below - but the whole dataset is June
2005 - June 2008). The "LST" format is "YYMMDDHHmm" and I would like to
get the hourly average of the "mph" for the summer months (spanning all
years). I have been trying to use "aggregate" but am not having much
success at all! any thoughts would be greatly appreciated.

No es un problema de tm tienes doc.corpus vacío
No es un problema de tm ni de SnowfallC ni de mcapply (por el path
utilizas linux, en windows mcapply según el manual no va bien)
No defines bien los objetos que pasas. Pasas doc.corpus en lugar de
corpus ( o asignas a corpus en lugar de a doc.corpus) .
Depura los programas cuando salga un error de objeto, como te pone en el
Error que pasas .

Loop sobre muchos data frames
Hola a todos!
Estoy en un proyecto de text mining y por razones de los recursos con que
cuento tuve que separar los archivos de texto de input del proyecto en
muchos archivos pequeños.
Luego de transformar cada uno de estos archivos en un corpus separado,
puedo aplicar limpieza sobre cada corpus, buscar n-gramas, construir cada
termDocumentMatrix y finalmente reunir todo en una sola TDM.

No es un problema de tm tienes doc.corpus vacío
Creo que lo que quieres hacer necesita esta línea de código justo después de
cargar el paquete tm:
inmortal = unlist(strsplit(inmortal, " ", fixed = T))
De esta forma, trabajas con palabras, y NO con las frases enteras...

Jorge, estimados colaboradores de R-help
Estuve tratando de utilizar un script para uno de los pasos en mi análisis,
que es transformar cada uno de los corpus en mi espacio de trabajo en un
objeto TermDocumentMatrix
Tengo un vector llamado bNames que lista todos los corpus que quiero pasar
a TDM, y construí los siguientes comandos:

Muchas gracias isidro,
a la noche reinstalo R y os digo si me ha funcionado. Perdona mi ignorancia
de novato pero no he entendido muy bien eso de avisar al desarrollador.
Entiendo que es a los de los paquetes, no?

S3 objects in S4 slots
Hello,
I am the maintainer of the stringkernels package and have come across
a problem with using S3 objects in my S4 classes.
Specifically, I have an S4 class with a slot that takes a text corpus
as a list of character vectors. tm (version 0.5) saves corpora as
lists with a class attribute of c("VCorpus", "Corpus", "list"). I
