I was going through the example below which is taken from the example section in the R documentation for accessing the function call stack. I am confused and I have 3 questions that I was hoping someone could answer. 1) why is y equal to zero even though the call was done with gg(3) 2) what does parents are 0,1,2,0,4,5,6,7 mean ? I understand what a parent frame is but how do the #'s relate

Hi I want to extract columns from a data frame using a vector with the desired column names. This short example uses the select argument in the subset function to accomplish what I am trying to do. Is there a better solution? #names of desired columns colnames <- c("col1","col3") #my data data <-

Hi, How can we set the environment for the minuslog function in mle()? The call in this code fails because the "ll" function cannot find the object 'y'. Modifying from the example in ?mle: library(stats4) ll <- function(ymax=15, xhalf=6) { -sum(stats::dpois(y, lambda=ymax/(1+x/xhalf), log=TRUE)) } fit.mle <- function(FUN, x, y) { loglik.fun <- match.fun(FUN)

Hi, I would like to extract columns from a dataframe using a vector of desired column names. The following working example uses the select argument in the subset function to accomplish what I am trying to do. Is there a better solution? Thanks. #my data data <- data.frame("col1"=c(1,2,3),"col2"=c("A","B","C"),"col3"=c(4,5,6))

I am trying to use the function "nlm" to find the mle. I want to use a generic function for the likelihood which would require me to use both the parameters and the data as arguments. But nlm requires the function to have only the parameters as arguments for this function (see example below). > testfun <- function(x,y) sum((x-y)^2) # x - parameters, y - data >

Hi, I?m trying to use Omega to index INEX dataset for Letor. But omindex told me these xml files are unknown. Olly told me I could tell omindex to handle them as HTML. (Thanks Olly :) ) Is it appropriate? Parth, could you give me some suggestions? Thank you! Jiarong Wei

Hi, How could I see the source code of functions in an R package? If we type ?function_name , we will see documentations of the function_name. If we type function_name, is what returns just the source code? Could we just save it in an .R file and modify as we want? However, it seems that sometimes the source code is hidden (or stored elsewhere?) As an example, could we see the source

I have a data frame whose first colum contains the names of the variables and whose second colum contains the values to assign to them: : kkk <- data.frame(vars=c("var1", "var2", "var3"), vals=c(10, 20, 30), stringsAsFactors=F) If I do : assign(kkk$vars[1], kkk$vals[1]) it works : var1 [1] 10 However, if I try with mapply

Hello all...I was having incredible difficulty in setting up my HP Color LaserJet 4500 to be shared on a Caldera 2.3 Linux server with access to it from Windows 2000 machines. I've been working about a week now (sadly enough) and I think I've made some progress mainly from information in newsgroups and online documentation. Here's what I have so far: I can print from the linux

Hi everybody, I have been examining on how I can use speex completely so I have one more question. I looked at examples and source code and it goes on. speex_bits_insert_terminator is called in speex_bits_write function. Shall I call this method one more time anywhere? Because in speexenc project, firstly speex_bits_insert_terminator is called then speex_bits_write is called when we assume that

Dear useRs! I have written a function that should pass argument "m" to the next function, however it does not! Please have a look at the function below that shows a problem and tell me what I am missing. As you can see, the "blocks" argument is passed corectly, while "m" is not. Best, Ales Ziberna opt.par.new<-function( #function for optimizig

Hi - I'm having a really hard time w/understanding R's get function, and would appreciate any help with this. Specifically, I'm using a for loop to call a function. I'd like the function to have access to the variable being incremented in the for-loop, i.e. t.fn <- function() return( get( "i" ) ) t.fn2 <- function() { for ( i in 1:5 ) cat( t.fn(),

I haven't done any R memory debugging lately, but https://www.mail-archive.com/rcpp-devel at lists.r-forge.r-project.org/msg10289.html shows how I used to have gdb break where valgrind finds a problem so you could examine the details. Also, running your code after running gctorture(TRUE) can help track down memory problems. -Bill On Wed, Feb 7, 2024 at 12:03?PM Therneau, Terry M., Ph.D.
