Hi, I'm trying to use pipes in R. By now, I could launch the linux command "wc" (to count words from a text), but I don't know how to capture the results, say in a vector of chars... Here is the R code I'm trying: :> f <- pipe("wc", open="w") :> writeLines(c("uno dos tres", "cuatro cinco", "seis"), f) :> close(f)

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

I have an ordered "set" of numbers, represented by a vector, say > X <- c(10:13, 17,18) > X [1] 10 11 12 13 17 18 then I have a "sub-set" of X, say > Y <- c(11,12,17,18) Is there a simple way in R to have a logical vector (parallel to X) indicating what elements of X are in Y, i.e., > Inclusion [1] FALSE TRUE TRUE FALSE TRUE TRUE I'm

I thought I've understood the 'order' function, using simple examples like: order(c(5,4,-2)) [1] 3 2 1 However, I arrived to the following example: order(c(2465, 2255, 2085, 1545, 1335, 1210, 920, 210, 210, 505, 1045)) [1] 8 9 10 7 11 6 5 4 3 2 1 and I was completely perplexed! Shouldn't the output vector be 11 10 9 8 7 6 4 1 2 3 5 ? Do I have a damaged

Is there any way to issue operating system commands and geting back the results, in R? I mean, for instance, in Linux, to execute from R the 'ls' command and getting back a list of files in the current directory, or, equivalently, in Windows/DOS, the 'dir' command? I'm not interested in the 'ls' or 'dir' commands it is just an example. Do you have any

I'm trying to figure out about factors, however the on-line documentation is rather sparse. I guess, factors are intended for grouping arrays members into categories, which R names "Levels". And so we have: * state <- c("tas", "sa", "qld", "nsw", "nsw", "nt", "wa", "wa",

I learnt that functions can be handled as objects, the same way the variables are. So, the following is perfectly valid: > f = function(a, b) { + print(a) + print(b) + } > > f1 = function(foo) { + foo(1,2) + } > > f1(f) [1] 1 [1] 2 > I also know that operators are functions, so, I can call: > '+'(1,2) [1] 3 > However, when I want to pass the

I'm trying to read a data file that contains characters from the Spanish language: > Station <- read.fwf("LosDatos.txt",widths=c(7,7,25,8,8,5),header=FALSE, + skip=3,n=separ[1]-4) Then the R interpreter issues the following message: Error en substring(x, first, last) : invalid multibyte string at '<d1>A, S.' Calls: read.fwf ->

I'm trying to produce a series of powers of a number as follows: |> 0.05^0:5 [1] 1 2 3 4 5 This is not the result I expected. I guess some kind of coercion happened, since, |> class(0.05^0:5) [1] "integer" Could anyone explain me what is happening here? Thanks, -Sergio.

Hi: Did anyone use apt-get install zaptel successfully? After apt-get instal zaptel, use "modprobe zaptel", get a "FATAL modul zaptel not found". Thanks.

Because I didn't find in R any functions similar to the function 'reduce' from Python, I'm writing a function "freduce" as follows: freduce <- function(f, vec, ValIni=NULL, StopIn=NULL) { # f: is any function that takes two arguments of the same type # vec: is a vector of n values accepted by 'f' # # Initially f starts with ValIni, if it's given

Muchas gracias, Sergio. Saludos cordiales.

I'm trying to write a Rscript program capable of reading several tables from the standard input. The problem is that the tables aren't in files because they are coming from another process that is generating them. From the R-console the following works pretty well: |> f <- stdin() |> t <- read.table(f) |> t2 <- read.table(f) |> t uno dos 01 3 4

There appears to be a quoting problem in the way R CMD install handles file names containing spaces, more specifically, in the way the argument is passed through to gzip. The install.packages command (from R) install.packages("~/Projects/R library/bar/eyetrackR_0.13.tar.gz", repos = NULL, type = "source") expands to

I want to superimpose two functions plots in the same page. The functions L0 and L1, defined below f0 <- function(mu, xm, ds, n) { 1 - pnorm((xm-mu)/(ds/sqrt(n))) } f1 <- function(mu,n) f0(mu, 386.8, 48, n) L0 <- function(mu) f1(mu, 36) plot(L0,ylim=c(0,1),xlim=c(360,420)) L1 <- function(mu) f1(mu,100) lines(L1) The plot of L0 works pretty well. However, when

Dear all, I am using R CMD SHLIB to compile a c++ code into a library (.so) and dyn.load to load this library into a R code. I am facing some problems in the c++ code that I can not figure out how to solve. Do you recomend any good way to debug this R + C++ program? If I was programming only in C++ I would use GDB. I would much appreciate any help or suggestion! Best regards, Charles -- Um

To superimpose two functions plots in the same page. The functions L0 and L1, as defined below, I use the following code: # An accumulative normal distribution function with # several parametres f0 <- function(mu, xm, ds, n) { 1 - pnorm((xm-mu)/(ds/sqrt(n))) } f1 <- function(mu,n) f0(mu, 386.8, 48, n) # Two functions with just the parameter mu L0 <- function(mu)

Dear R-developers, even though I may not be the first one to encounter the problem described below, I would really appreciate some help or a link to a forum where this topic is being discussed. Probably I am simply misinformed on the usage of structRstart but see for youselve. I did check multiple forums and the whole internet on the topic without success. I am using the shared library version
