Hi: I am experiencing a problem with dataset diamonds in ggplot2. When trying execute the summary(diamonds) statement, the following error message is displayed: Error in summary(diamonds) : Cannot open file 'C:/Users/James/R_Pgms/R/R-2.8.1/library/ggplot2/data/Rdata.rdb': No such file or directory
Can you please advise me? A complete history of commands leading up to this problem is as follows. I have also included in this history a set of parallel statements (involving a different dataset, Davis, in a different package, car) for which the summary command executed OK. My first three commands were as follows: > library(car) > library(ggplot2) > search() The displayed results of the search command confirmed that both packages were now in the search path. The next three commands were as follows: > data(Davis) > data(diamonds) > ls() The displayed results of the list command confirmed that both datasets were in the workspace. Next, the following statement provided the expected dataframe summary > summary(Davis) However, a similar statement for the dataframe diamonds resulted in the error message described above. I am running on a PC with Vista and SP1 The sessionInfo() command displayed the following: R version 2.8.1 (2008-12-22) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252 attached base packages: [1] grid stats graphics grDevices datasets utils methods [8] base other attached packages: [1] ggplot2_0.8.1 reshape_0.8.2 plyr_0.1.4 proto_0.3-8 [5] car_1.2-11 rcom_2.0-4 rscproxy_1.0-12 loaded via a namespace (and not attached): [1] tools_2.8.1 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
