Then it does nothing with it; once you leave the function’s scope, it’s lost. If you want the function to operate on the … Read more

The absolute best you can do in this case is to write an empty string … Read more

Yes, functions are located in a specific place in memory. In the context of Virtual Memory (opposed to physical caches), they are stored below the Heap and below a section called the Data (global variables) in a section called Text. All of this is loaded up when the executable is read; this is all done … Read more
Because is a summer saturday and I’m happy, I’ve written a little code for you, but it’s incomplete. The only “prebuilt” function that the code uses is puts and I don’t see way to don’t use it. The code has two problems: The strings cannot be longer than 64 bytes. If they are longer the … Read more

This answer assumes reading of the earlier question and comments so is not “code only”. qt = expand.grid(Month=c(“G”,”J”,”M”,”Q”,”V”), Year=1975:2016) query_names_vec <- apply(qt, 1, function(x) paste0(“CME/GC”, paste0( x, collapse=””) ) ) > head( query_names_vec ) [1] “CME/GCG1975” “CME/GCJ1975” “CME/GCM1975” “CME/GCQ1975” [5] “CME/GCV1975” “CME/GCG1976” 10 solved Loop R with Quandl as optional
Since no return value is specified, it returns null. The return statement here is optional since it does not return any value and is located at the end of the function. You can use the return statement to jump out of the function explicitly without necessarily reaching the end of the function. See Returning values … Read more
