[R] Error while displaying help page of a function existing inside two different loaded libraries
Dear R users, I recently upgraded R from version 2.15.3 to version 3.0.0 (after removing version 2.15.3 and cleaning installation directory) using the package provided by openSUSE (R-base). I am now running into an issue when two loaded packages share the same name for a function. For example, "image" (packages graphics and gstat) and "dotchart" (packaged graphics and survey) functions. In R-2.15.3, a choice was displayed, in order to choose the function within the desired package. In R-3.0.0, an error appears inside the web browser (Firefox): ?image Error in httpd("/library/NULL/help/image", NULL, NULL, c(48, 6f, 73, 74, : replacement has length zero ?dotchart Error in httpd("/library/NULL/help/dotchart", NULL, NULL, c(48, 6f, 73, : replacement has length zero Did anybody else already encounter this issue? Or is it a problem with my own installation? Herewith is the result of "sessionInfo" > sessionInfo() R version 3.0.0 (2013-04-03) Platform: x86_64-suse-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] survey_3.29-4 gstat_1.0-16 sp_1.0-8 loaded via a namespace (and not attached): [1] grid_3.0.0 intervals_0.14.0 lattice_0.20-15 spacetime_1.0-4 [5] tools_3.0.0 xts_0.9-3 zoo_1.7-9 Best Regards, Pascal Oettli
