Hello, I changed the name of a function, and updated my R packages with update.packages(ask=FALSE), and I have had a curious (to me) change in show method. I am developing a package, and a generic show method I defined for my S4 class is not autocalled when I type the object name - object_name; however, the show(object_name) works as expected. I have included the output from sessionInfo(): R version 3.3.2 (2016-10-31) Platform: x86_64-redhat-linux-gnu (64-bit) Running under: CentOS Linux 7 (Core) locale: [1] LC_CTYPE=en_US.utf8 LC_NUMERIC=C [3] LC_TIME=en_US.utf8 LC_COLLATE=en_US.utf8 [5] LC_MONETARY=en_US.utf8 LC_MESSAGES=en_US.utf8 [7] LC_PAPER=en_US.utf8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.utf8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] genotypeR_0.0.0.9000 ggplot2_2.2.1 loaded via a namespace (and not attached): [1] Rcpp_0.12.10 lattice_0.20-35 zoo_1.8-0 MASS_7.3-47 [5] grid_3.3.2 plyr_1.8.4 gtable_0.2.0 magrittr_1.5 [9] scales_0.4.1 stringi_1.1.5 rlang_0.1.1 reshape2_1.4.2 [13] lazyeval_0.2.0 doBy_4.5-15 Matrix_1.2-10 tools_3.3.2 [17] stringr_1.2.0 munsell_0.4.3 colorspace_1.3-2 tibble_1.3.1 I appreciate any help with this problem. kindest regards, Stephen -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods.
