Is there any version of grep that gets information from the filename? For example: x <- "myfile.txt" y <- grep.file("my text", x) should return in y the lines with my text.
I know that x <- "myfile.txt" y <- grep("my text", readLines(x)) will probably work, but maybe there's a more direct (and less memory hungry) option.
