Dear users, I have a problem when using the testInstalledBasic function in the tools package on my windows 7 machine. I specified the environment variables as stated in the Installation and administration manual (Sys.setenv(LC_COLLATE = "C", LANGUAGE = "en")) and ran the function on an installation without additional packages. However the test fails on the script "reg-tests-2.R". I think that the problem is the fact that the local LC_ALL should be set to "C" to correctly compare the results for read.csv("EmbeddedNuls.csv"). This locale is set within the function however all test scripts are submitted using CMD BATCH. Therefore setting the locale within the function seems to have no effect. I tried setting the locale within Rprofile.site but within CMD BATCH --vanilla is used. Are my assumptions correct and if so does anybody know a solution for this problem? Thank you, Richard sessionInfo: R version 3.1.2 (2014-10-31) Platform: i386-w64-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base [[alternative HTML version deleted]]
