Hello, I want to report a bug in R that is limiting my capabilities to export a matrix with write.csv or write.table with over 2,147,483,648 elements (C's int limit). I found this bug already reported about before: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17182. However, there appears to be no solution or fixes in upcoming R version releases.
The error message is coming from the writetable part of the utils package in the io.c source code(https://svn.r-project.org/R/trunk/src/library/utils/src/io.c): /* quick integrity check */ if(XLENGTH(x) != (R_len_t)nr * nc) error(_("corrupt matrix -- dims not not match length")); The issue is that nr*nc is an integer and the size of my matrix, 2.8 billion elements, exceeds C's limit, so the check forces the code to fail.
