Installing PDFtotext in R


Installing PDFtotext in R



I am trying to run the PDFtotext package in R.


PDFtotext



When I run these commands:


library(tm) pdf=readPDF(control=list(text="-layout"))(elem=list(uri=uri), language="en", id="idi")



I get this error:



Error in system2("pdftotext", c(control$text, shQuote(x), "-"), stdout = TRUE) : "pdftotext" not found



In addition: Warning message: running command "pdfinfo" "C:*****NCLR AR 2005.pdf" had status 127



Does anyone know what the problem might be?





Sys.which("pdftotext") is ""? I.e. the file is not found. Have you installed it? You may want to try the package pdftools as an alternative to read pdfs.

Sys.which("pdftotext")


""


pdftools





This function of the tm library requires that pdftotext and pdfinfo are installed on your computer. You can download precombiled binaries for the most common operating systems here. These programs are not installed in or by R, as the title of your question suggests. They need to be installed as separate programs on your system.

In widows add the binary to your path. System-->Advanced -->Environment Variables -->add the directory containing the pdftotext.exe

C++ thread error: no type named ‘type’ MINGW

C++ thread error: no type named ‘type’ MINGW I'm currently doing a project for my operational systems class and I have to make a program to find prime numbers to run in threads. So I did this: #include <iostream> #include <cmath> #include <thread> #define THREADNUMBER 100 using namespace std; int CONTADOR = 0; int CONTADORTHREADEXECUTADA = 0; int primeRange(int v1, int v2) { int a, limit; bool isprime; for (int i = v1; i <= v2; i++) { if (i % 2 != 0 && i % 3 != 0) { isprime = true; limit = i / 2; if(i == 1) isprime =false; limit = (int)sqrt(i); //General case for(a=2; a <= limit; a++){ if(i % i == 0 && i != 2){ isprime = false; break; } } if (isprime) { CONTADOR++; } } } CONTADORTHREADEXECUTADA++; return 1; } int main(int argc, char *argv[ ] ) { int number1 = atoi(argv[1]); int num...

Decreasing a static image progress bar horizontally in SDL

Decreasing a static image progress bar horizontally in SDL In my project, I have a decreasing timer progress bar PNG image on display. This image and its background can be found at the below link: https://s3.eksiup.com/df7dd38f781.png My goal is to make the bar decrease starting from the upper green side to the lower red side. My code for this is the following: void EntityTimer::OnRender(SDL_Renderer *ren) { SDL_Rect currRect,dstRect; double rem=0.0; memcpy(&currRect,&origRect,sizeof (SDL_Rect)); memcpy(&dstRect,&origRect,sizeof (SDL_Rect)); if (timerObjPtr->remainingDuration>timerObjPtr->durationInMilisec) timerObjPtr->durationInMilisec=timerObjPtr->remainingDuration; rem=((double)timerObjPtr->remainingDuration/timerObjPtr->durationInMilisec); currRect.h=(origRect.h)*rem; currRect.h = currRect.h; dstRect.x=0; dstRect.y=0; dstRect.h=currRect.h...

How to input without newline? (Python)

How to input without newline? (Python) I am trying to create a simple file editor in Python via the console (called PyCons). Here is my current program: def PyCons(f): file = open(f, "r") appe = open(f, "a") print("n=====nPyCons Editor, v1.2nPython 3.6.1n") global i i = 0 for line in file: i += 1 print(" {}| ".format(i) + line, end='') for k in range(10000000000000): print("n {}| ".format(i+1), end='') inp = input("") if inp == "@PyCons.save()": print("n=====") break else: i += 1 appe.write("n" + inp) I used the end method to make sure that the existing code in the file was printed properly in its line format, but the input function does not have an end attribute. So, when I go to enter code in the editor: end input end PyCons("magic.html") ... ===== PyCons Editor, v1.2 Python 3.6.1 1| <p>Hello!...
