Re: [R] Using readLines on a file without resetting internal file offset parameter?

I agree that file's use of its 'mode' argument can be confusing. That is one reason I didn't use it my example and made an explicit call to open() after calling file() without the mode argument. (Having to distinguish between 'binary' and 'text' mode on Windows, 'rb' and 'rt' or 'wb' and 'wt', ca

[R] problem in loop using windows executable

Dear all, I am trying to develop a R script that basically uses a loop that includes 5 main steps: (1) it runs a windows executable file outside R that requires a set of *.txt files using the shell function (Note: I have tried system and system(shhQuote()) and the problem remains), (2) it imports

Re: [R] Using readLines on a file without resetting internal file offset parameter?

Yeah of course you should close the file when done. I didn't give a complete code snippet. In any case, a quick glance at the documentation seems to imply that opening a file as file('filename') will defer the choice of mode (i.e. is it 'r', 'w', etc.?) until it is first used. In my case the f

Re: [R] Using readLines on a file without resetting internal file offset parameter?

Thanks for the response! I'd rather keep the file open than close it, since it would flush the internal buffer. The whole reason I'm doing this is to take advantage of the buffering and closing it would defeat the purpose. I actually just found a solution which is to open the files with the "r

Re: [R] Using readLines on a file without resetting internal file offset parameter?

I meant you should close the file when you are done with it, not after every few lines. File descriptors are a limited resource. As for the rationale for the default behavior, there is a common use pattern of reading and parsing an entire file (or url, etc.), examining the results, and trying agai

[R] Using readLines on a file without resetting internal file offset parameter?

Hi everyone, I would like to read a file line by line, but I would rather not load all lines into memory first. I've tried using readLines with n = 1, but that seems to reset the internal file descriptor's file offset after each call. I.e. this is the current behavior: --- bash $ echo 1
