Hello, All, I want to write a function to do some works based on the arguments. For example, bind some variables (arguments) as this: myfunction <- function(arg1, arg2, arg3, ?) { x <- cbind(arg1, arg2, arg3, ?) } myfunction(arg1, arg2, arg3, ?) The function can automatically determine the number of arguments and bind them, which means if I assign 2 arguments, the function can bind

Dear all, I just want to determine if the characters in a character string are the same or not. For example, temp <- c("aa", "aA", "ab") How do I determine the first one have the two same ?a?, and the second and third have the different characters? Thanks in advance.

Dear all, I have a dataset that looks like this: x <- read.table(textConnection("col1 col2 3 1 2 2 4 7 8 6 5 10"), header=TRUE) I want to rewrite it as below: var1 var2 var3 var4 var5 var6 var7 var8 var9 var10 1 0 1 0 0 0 0 0 0 0 0 2 0 0 0 0 0 0 0 0 0 0 0 1 0 0

Dear all, I am trying to write a script to pause the execution of a function and provide some additional commands to the function and then continue execution of the function. For example, when my function detects a wrong number in a dataset, the function pauses automatically and returns information on the screen: ?There is a wrong number in the dataset. Would you like to correct it? ? If I

Dear all, I have a question about how to set arguments in my own function. For example, I have a function that looks like this: my.f <- function(a = x1, b = x2) { x1 = equation 1 x2 = equation 2 x3 = equation 3 y = a + b } x1, x2, and x3 are temporary variables (intermediate results) calculated from other variables within the funciton. I want to use two of these three

Hello, All, I have a dataset that looks like this: x <- matrix(c( 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1, 2, 1, 1, 2, 1, 1, 3, 1, 1, 3, 1, 1, 3, 1), ncol = 5, byrow = T, dimnames = list(1:10, c("gender", "race", "disease"))) I want to write a function to produce several matrices including only ?TRUE? and ?FALSE? for the different levels of the

Dear all, I have a question about deleting components of a list. For example, I have a list that looks like this: [[1]] var1 var2 var3 1 3 4 2 2 1 [[2]] var1 var2 var3 2 5 1 2 1 7 [[3]] var1 var2 var3 1 6 7 3 8 4 How to delete, say, the first columns of the list or the second rows? Thank in advance. Lisa -- View

Dear all, I have two sets of numbers that look like a <- c(1, 2, 3, 3, 4, 4, 5, 6, 1, 2, 2, 3, 1, 2, 1, 2, 3, 3, 4, 5, 1, 2, 3, 4) b <- c(1, 5, 8, 9, 14, 20, 3, 10, 12, 6, 16, 7, 11, 13, 17, 18, 2, 4, 15, 19) I just want to use ?b? to encode ?a? so that ?a? looks like a1<- c(1, 5, 8, 8, 9, 9, 14, 20, 3, 10, 10, 12, 6, 16, 7, 11, 13, 13, 17, 18, 2, 4, 15, 19) Does anyone have a

Dear all, I have a dataset that looks like this: inividual var1 var2 ? 1 1 1 ? 2 1 2 ? 3 2 1 ? 4 2 2 ? ? ? ? ? I will random sample 2 individuals from this dataset based on a set of random numbers, e.g., rn1 <- c(0, 0, 1, 1), rn2 <- c(0, 0, 2, 0), rn3 <- c(1, 0, 0, 1), rn4 <-

Hi, everybody, I just want to pass arguments to a function as below: range <- c(0.1, 0.5) runif(1, range) But it doesn?t work. Does anyone have any suggestions to offer? Thanks.

Function/file names are hypothetical. Say I have written myfunction.R, which calls myfunction.c via .C("myfunction", ...). I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c in the terminal. Then, in the R console: dyn.load("myfunction.so") source("myfunction.R") test <- myfunction() # works fine So everything is in order, myfunction works

Hello, R users, I have a dataset that looks like this: id var1 var2 1 1 3 2 3 1 3 2 1 4 1 2 5 2 3 I want to split one column to two columns with 1 = 1 and 1, 2 = 1 and 2, 3 = 2 and 2: id var1.1 var1.2 var2.1 var2.2 1 1 1 2 2 2 2 2 1 1 3 1 2

Hi, everybody, I have a problem and need your help. There are two columns that look like this: [1,] "t" "f" [2,] "f" "t" [3,] "t" "f" [4,] "t" "t" [5,] "f" "f" I just want to generate the third column based on these two columns. First, I randomly choose one of the two columns,

Hi everyone, I made some tests with Rcmdr, to add a function with default parameters : For example (very simple): myfunction<-function(var="314"){ print("hello") print(var) } if I run myfunction() directly i see : > myfunction() [1] "hello" [1] "314" it's ok. But if i edit de Rcmdr-menu.txt (in

I have a function myFunction(beta,x) where beta is a vector of coefficients and x is a data frame (think of it as a matrix). I want to optimize the function myFunction() by ONLY changing beta, i.e. x stays constant, with 4 constraints. I have the following code (with a separate source file for the function): rm(list=ls()) source('mySourceFile')

Dear All, I hope you don't mind helping me with this small issue. I haven't been using R in years and I'm trying to fill in a matrix with the output of a function (I'm probably using the Matlab logic here and it's not working). Here is my code: for (i in 1:length(input)){ out[i,1:3] <- MyFunction(input[i,1],input[i,2], input[i,3]) out[i,4:6] <-

Dear all, I have the following problem: I have written a function genereating to plots, eg myfunction <- (data, some.parameters) { #some calculations etc . par (mfrow=c(1,2)) plot1(......) plot2(.....) } which works fine. But for analysing several variants, I tried a slope, eg: par (mfrow=c(5,5)) for ( i in 1:10) { myfunction(data, i) } Off

I am interested in running R commands asynchronously. My first choice is in the same R session that I am currently in. Here, the goal would be to run something like RunAsynchSameSession(myfunction(), "outputname.rda") Once RunAsynchSameSession had started myfunction(), RunAsynchSameSession would complete immediately. myfunction would keep going. It is OK if execution of the

Marc and many other people ( whose names escape me ) have been very helpful in explaining the use of lapply to me. In his last response, Marc explained that if tradevectors is a list of vectors of different lengths ( excuse my terminology ) then lapply(tradevectors,function(x) G[x]*B[x] ) will go through each component of the list as if it was a vector and apply the element by element

Dear All I have a program that breaks at the following lines of code: bigfunction = { ... object1 = myfunction(x) object2 = strsplit(object1, ",")[[1]] ... } where myfunction is defined elsewhere outside of bigfunction. The error I get is "error in strsplit() -- object1 not found". However, when I insert browser() into my code so that the above reads, bigfunction = {
