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 <-

Hello, My configuration is : Card 0 - kernel dummy sound card Card 1 - my soundcard I have a jackd running in background.

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))

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 Alls Sorry for my newbe question I want to decode a speex multi frame stream I got 38 bytes packets and make 800 bytes buffer this is my simple code CSpeexCodec::CSpeexCodec(void) { // speex_bits_init(&m_speexBitsOut); m_pSpeexEncStateOut = speex_encoder_init(&speex_nb_mode); int nEhc=1; int nSamplePerSec = SAMPLES_PER_SEC; static int nQuality = 8;

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 could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any

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, Is it possible use a loop to process many data frames in the same way? For example, if I have three data frames, all with same variables df_bs_id1 <- read.csv("test1.csv",header =TRUE) df_bs_id2 <- read.csv("test2.csv",header =TRUE) df_bs_id3 <- read.csv("test3.csv",header =TRUE) How could I would implement a code loop that , for instance, would

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

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

I'm in a bit beyond my depth with environments and such. The environment of a particular function, which I've set so it should have the things it needs, seems to be getting "lost" at some point during a call sequence. It's hard to come up with a _simple_ reproducible example, although if anyone's sufficiently interested I can post the package somewhere -- with the

Dear R Developers, I am writing a function that would save all objects in all environments 'visible' from the point where the function is called (very much like save.image, but kind of saving the entire stack). I figured that the call lapply (seq(0, sys.nframe()), function(i) ls(sys.frame(i), all.names=T)) will list all such objects. However not all of them seem to be visible, see a

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.

Hello, Could you please explain or send an example for decoding a packet that contains multiple Speex frames. According to the API document the speex_decode_int() decodes only one frame of speech.
