Hi all, Is there any grid search function to compute the maximum likelihood for a random variable? thanks, Samor --------------------------------- [[alternative HTML version deleted]]

Hello everybody, I am trying to install the library stepplr under windows (http://www.maths.bris.ac.uk/R/web/packages/stepPlr/index.html), in order to use the function plr, but I still have problem to find the right link for this purpose! I am very thankful for your help! Samor

Dear all, I am very thankful, if you could tell wheather it is possible to write paste("Mus., 10 ", expression(mu)," g", sep="") Thank you in advance, Samor --------------------------------- [[alternative HTML version deleted]]

Hello, Is there any test  for bimodality in R that x <- c(rnorm(1000,0,1),rnorm(1000,3,1)) hist(x,nclass=100) Thank you in advance for any help. Regards, Samor [[alternative HTML version deleted]]

It seems that the dbReadTable() method provided by RMySQL could not get rid of the headers, neither the index column... So 1. Can I use read.table() method to get a table of MySQL database? >From the help document the argument of 'file' of read.table() method could be a connection... 2. How can I obtain a matrix from the database table contains all elements except the headers and the

I've been putting together a package that defined generic methods for database access. The packages is called "Rdbi." It borrows as much as possible from existing database packages / proposals. I'd like to start a discussion about the proposed interface. Here's what I've come up with so far: # # Rdbi: connectionMethods.R # dbConnect <- function(dbObj, ...)

Dear All, I am wondering on how to use the abline.xyplot with xyplot such that I will have different vertical lines for each panel. More sepcifically, suppose that the xyplot generates 4 panels defined by the combination of two binary variables: X_1 and X_2. i.e. xyplot(Y ~ Z | X_1*X_2, data = df) I want something like: abline(v = 5) if X_1=0 and X_2 = 0 abline(v =

Hi, I'm experimenting with using (R)SQLite to do data management. Here are two little problems that I've encountered: 1. The presence of ',' in string values causes trouble since ',' is also the delimiter used in the SQL statement. 2. A newline '\n' line attached to the last string value of each row. Some examples: > library (RSQLite) Loading required

Hey, folk. I am trying to get many figures by using the function "xyplot" in the library "lattice". I tried to using the loop to finish it quickly. But I cannot open the saved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot". The

Hi All, I'm trying to add a map on the following lattice plot, but not correctly... can anyone help please... R Code: require(lattice) us.map <- map(plot = FALSE, fill = TRUE) Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes, panel = function(...) { panel.polygon(us.map$x,us.map$y) panel.xyplot(...) } ) Any help would be

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

What am I doing wrong, or is the \r that I'm getting in the example below a bug? > a <- (1:10) > b <- (LETTERS[1:10]) > df <- as.data.frame(cbind(a, b)) > > df a b 1 1 A 2 2 B 3 3 C 4 4 D 5 5 E 6 6 F 7 7 G 8 8 H 9 9 I 10 10 J > library(RSQLite) > drv <- dbDriver("SQLite") > con <- dbConnect(drv, dbname = "Test")

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37. I've read many postings about this but have not found a mention of my particular problem (some closely related). I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

All: I am using RSqlite and want to be able to update individual values in a record, such as with this simple example: library(RSQLite) drv<-dbDriver("SQLite") con<-dbConnect(drv,"test.db") my.data<-data.frame(countries=c("US","UK","Canada","Australia","NewZealand"),vals=c(52,36,74,10,98))

HI. I make this code: getdata<-function('a','b','c' ,'d','e','f'){ drv <- dbDriver("SQLite") con<-dbConnect(drv, "sqlite.db") lt<-dbListTables(con) myf<-data.frame(NULL) for (i in 1:length(lt)) { myfile<-dbReadTable(con,lt[i]) myfile1<-myfile[-c(14:44)] myfile1$MODEL<-gsub(" ",

Hi, I recognized that the function 'setReplaceMethod' is creating a character vector in the user workspace having the name (e.g. "newClass") of the class used as value. If you can sort out a mistake by myself, I would like you to file a bug report. BBFN, Jonathan setClass("newClass", representation(value="numeric")) setMethod(f = "initialize",

I am working off an example from Deepayan Sarkar's Lattice:Multivariate Data Visualiization with R. I am trying to create Figure 5.6, essentially, but I would like to be able depict different metro areas. These of course have different lat/longs, so I need to make different graphs. BUT (and this has been the tricky part), I would like to produce graphics for each metropolitan

Hola a todos, Tengo que construir un gráfico para una base de datos que tengo en el que representar para los individuos de esta base su altura vs peso en función de su edad. Para ello, hay que utilizar los gráficos condicionados. En primer lugar usé la función coplot pero cargando el paquete lattice se pueden utilizar funciones que generan gráficos más completos, como es el caso de la función
