Hello, All: I have a 4.54 GB file that I'm trying to read in chunks using "scan(..., skip=__)". It works as expected for small values of "skip" but goes into an infinite loop for "skip=1e11" and similar large values of skip: I cannot even interrupt it; I must kill R. Below please find sessionInfo() with a toy example. My real problem is a large corrupted Thunderbird email file. It's file type "Mork", which is mostly standard characters with "\n&quot...

Skipping lines is done by two nested loops. The outer loop counts the lines to skip; the inner loop reads characters until it encounters a newline or end of file. The outer loop doesn't check for EOF and...

Hi, I have a failing unit test in my package tryCatchLog on the CRAN build infrastructure (https://cran.r-project.org/web/checks/check_results_tryCatchLog.html) with "R Under development (unstable) (2019-09-27 r77229)" and the unit tests just ensures consistent behaviour of R (not of my package) as a precondition: The failing unit test is caused by >

Analogously, x %/% L and L %/% x suffer less from cancellation and return values corresponding to limits for large L. * grepl(NA, *) now returns logical as documented. * options(warn=1e11) is an error now, instead of later leading to C stack overflow because of infinite recursion. * R_tryCatch no longer transfers control for all conditions.
