Hi, I am using XML::readHTMLTable and getting the below error. Does anyone know why? Does this function not work with https? I didn't see anything in help about that. > library(XML) > wampage<-readHTMLTable('https://hr-workforce-analytics.llnl.gov/wf_pi_pop.html',1) Error in htmlParse(doc) : File https://hr-workforce-analytics.llnl.gov/wf_pi_pop.html does not exist Dan

Hi, I can't get the colClasses option to work in the readHTMLTable function of the XML package. Here's a code fragment: require("XML") doc <- "http://www.nber.org/cycles/cyclesmain.html" table <- getNodeSet(htmlParse(doc),"//table") [[2]] # The main table is the second one because it's embedded in the page table. xt

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

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

Hi, Using R 2.15.1 on Windows 7. Have installed both versions 32 and 64bit. In both of them among others I have installed a package rgenoud When I open R gui of 32bit and write library(rgenoud) it responds by showing a functional rgenoud version 5.7-8. The same it does on Rgui 64bit. Now I am working in cygwin (v. 1.12.4.0) with xwin. Normally before when I had installed a package, I only had

Dear useR's, today I stumbled over an interesting phenomenon: First, I created a named numeric vector with a certain class and several attributes via the structure() function. After that, I implemented a simple print method for this class. When calling this function it produces an endless loop of print calls until R crashes. :/ What is going on here? Is this a bug or have I done something

( A similar problem is also reported by Sebastian P. Luque with library(maptools) library(trip) in the vignette as below ). I am writing a vignette which loads RMySQL and RPostgreSQL. This produces the warning: Loading required package: DBI Warning in .simpleDuplicateClass(def, prev) : A specification for class ?dbObjectId? in package ?RPostgreSQL? seems equivalent to one from package

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 = {

Hi all, I have a function - let's call it "myfunction". This function is based on some random number generator. Now, once in a while the function will break/crash depending on the random number it generate inside the function. To avoid the problem, what I intend to do is the following: 1. Catch the try-error using class. 2. Redo the function if it returns "try-error" 3.

Dear all, Does R offer a means by which a function can determine whether its return value is assigned? I am using R 2.4.1 for Windows. Suppose what I am looking for is called "return.value.assigned". Then one might use it like this myfunction <- function () { # Create bigobject here if (return.value.assigned()) { bigobject } else {

Hello, everyone, I encounter a strange problem about llvm type i64 and C++ type int64_t. I instrumented a program to call the function 'myFunction' in the C++ shared library. 'myFunction' is something like this: int64_t myFunction() { int64_t retValue; ... std::cout << "retValue: " << retValue << "\n"; return retValue; }

Dear all How can I obtain the name of the argument passed in a function? Here is a simplistic example of what I would like to obtain: myfunction= function(name) { print(paste("The parameter name was",unknownFunction(name)) } myfunction(myobject) [1] "The parameter name was myobject" Thanks Francisco

Hi R experts, I have been playing with library(XML) recently and found out that readHTMLTable workls flawlessly for some website, but it does give me an error like below ... Error in function (classes, fdef, mtable) : unable to find an inherited method for function "readHTMLTable", for signature "NULL" let's say..for example, this code works fine a

Dear R community, You may have the solution to how to construct a function using the function "source()" to build the function; i.e. myfunction <- function(...){ source('file1.r') source('file2.r') } After compiling and installing the "myfunction" in R, then calling the "myfunction" gives an error because the content of 'file1.r' and
