Dear all, I'm trying to create a virtual S4 class with some subclasses. I noticed that adding slots to this class increases the memory use and slows the functions down. Note that I'm adding very small slots (integer or character both of length 1).
I've made a reproducible example at https://github.com/ThierryO/testvirtualclass. The R CMD check --as-cran fails on the tests. Some of the output of R CMD check * using R version 3.2.0 (2015-04-16) * using platform: i386-w64-mingw32 (32-bit) * using session charset: ISO8859-1 * using option '--as-cran' * checking tests ... Running 'testthat.R' [125s] ERROR Running the tests in 'tests/testthat.R' failed. Last 13 lines of output: Execution halted Error: C stack usage 16583636 is too close to the limit at that point R crashes and uses about 3.7 GB RAM Any ideas on what is going wrong? Am I using the virual classes in the wrong way? Best regards, ir.
