Aplicación de lapply()
Estimados su ayuda con la ejecución del comando lapply()
Tengo creada la siguiente función invertir(matriz,n) que me permite cambiar
la posición de los elementos de una matriz.
invertir<-function(Matriz,n){
a<-Matriz
b<-matrix(c(rep(0,n*n)),n,n)
c<-matrix(c(rep(0,n*n)),n,n)
for (i in 1:n) {b[i,]<-a[(n+1)-i,]}
for (j in 1:n) {c[,j]<-b[,(n+1)-j]}
return(c)
}

reshaping some data
Hi all,
I have a data.frame with the following colnames pattern:
x1 y11 x2 y21 y22 y23 x3 y31 y32 ...
I.e. I have an x followed by a few y's. What I would like to do is turn
this wide format into a tall format with two columns: "x", "y". The
structure is that xi needs to be associated with yij (e.g. x1 should
next to y11 and y12, x2 should be next to y21, y22, and

Suggestion: 'method' slot for format.ftable()
Dear R-developers,
I would like to suggest a 'method' slot for format.ftable() (see an adjusted
'format.ftable()' below, taken from the source of R-2.15.2).
At the moment, format.ftable() contains several empty cells due to the way the
row and column labels are printed. This creates problems (= unwanted empty
columns/rows) when converting an ftable to a LaTeX table; see an

Muchas gracias Carlos,
Me da error al hacerlo. Mi variable donde quiero que localice las palabras
de la lista tiene más de una palabra, no se si puede ser por eso.
Gracias

sum multiple csv files
Hi, I am pretty new to R and I would apreciatte very much your help to
solve my problem. I have 40 csv files that have the same structure, and I
want to merge them into a single data frame.
I already have load and combined all the cvs files into a large list, and I
created two
filenames <- list.files('data',full.names=TRUE)
All_data <- lapply(filenames,function(i){

Pasar palabras de una lista a una variable del dataframe
Buenas tardes,
Tengo una lista de 600 palabras. Quiero saber cuántas de esas palabras
aparecen en cada observación de mi variable "texto". La variable "texto"
es de tipo caracter. ¿Cómo lo haríais?
Muchas gracias.

sum multiple csv files
Your message seems unclear, and as evidence the respondents are giving various answers. You should provide a small sample of input and output data as it would look in R to avoid this kind of thrashing about. See [1][2][3] for guidance. Note that you also really need to figure out how to make sure your email program sends plain text, because HTML formatting WILL be stripped by the mailing list

interaction terms formula error
Hi,
I'm trying to fit a binary logistic regression model, and would like to consider certain characteristics B and C only for people with variable A=1 and not for those with variable A=0, so I'm trying to do the following:
model<- lrm(formula= y ~ A: (B+C) + D + E +...)
I've had no problem with adding interaction terms using " * ", but every time I try to use

Thanks Simon, by cloning a smooth construct do you mean copying and
modifying the smooth constructor code? Could you pleas elaborate on
your answer? Which is the Predict.matrix method?

recomendación de librerías para mapas en Shiny
Hola:
En la versión gratuita no existe límites en el número de usuarios y
tampoco existe límites en el número de desarrolladores.
Con la versión gratuita para publicar una aplicación debes subirla al

allí se ejecuta con los permisos que tenga el usuario que ejecuta el

bug: write.dcf converts hyphen in field name to period
write.dcf(list('my-field' = 1L), tmp <- tempfile())
cat(readLines(tmp))
# my.field: 1
However there's nothing wrong with hyphenated fields per the Debian
standard:
https://www.debian.org/doc/debian-policy/ch-controlfields.html
And in fact we see them using hyphenated fields there, and indeed read.dcf
handles this just fine:

[LLVMdev] Where is steens-aa and ds-aa?
Hi,
I just found -steens-aa and -ds-aa Alias Analysis listed in documents do
not exist in my llvm-2.3 code. Both from opt -help and the lib/Analysis.
And then I go to download the llvm-2.5 version, there is still no these 2
options. Where are they?

[LLVMdev] Are ds-aa and steens-aa still in Poolalloc?
Hi,
I was looking at the LLVM's alias analysis documentation
(http://llvm.org/docs/AliasAnalysis.html#exist) and it seems that
poolalloc has ds-aa and steens-aa. However, I followed the
instructions to use these passes, but I wasn't able to use them. Also,
I found this: http://old.nabble.com/DSA-or-rDSA---td32576486.html
saying that they were removed from poolalloc. Is that true? If so,
