Hi, I have a loop as follows, dataStr <- character(0) repeat{ fstr<-read.socket(sockfd) if(fstr=="") break dataStr<-paste(dataStr,fstr) } at what point does dataStr stop accepting(gets full)? I'm sending millions of records over the socket and need to know if all of it can go into dataStr. Also, Incase all of it cannot go into dataStr, I need to parse each

Hello, all I am building a R package using Fortran source code. The Fortran code is a subroutine. I can use "R CMD SHLIB bar.f -o bar.o" to create the shared library. For the R package, I put the fortran file in the src/ and I use R code as follows: ".First.lib"<-function(libname,pkgname){library.dynam("barpkg",pkgname,libname)} barfun<-function(n,x){
