K, it seems like I have a problem. I'm trying to access the Hmisc package, which of course is installed. And i get this error:
in Rstudio:
Loading required package: ggplot2 Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ‘Rcpp’ Error: package ‘ggplot2’ could not be loaded
in R:
Error in unloadNamespace(package) : namespace ‘ggplot2’ is imported by ‘caret’ so cannot be unloaded Error in library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc, : Package ‘ggplot2’ version 1.0.1 cannot be unloaded
I already have ggplot2 and caret but I wasn't sure about Rcpp, so I decided to install both. For that I used the function: install.packages('', dep = TRUE) The ggplot 2 installs smoothly and the same with Rcpp but with a warning:
Warning in install.packages : cannot remove prior installation of package ‘Rcpp’
Same warning in caret.
Anyway, nothings changes when I try to access the Hmisc library.
Maybe it helps to say I updated both (R and RStudio) few days ago with the latest versions and the installed packages are in my working directory. Something was/is definitely wrong, cause I got some error running a program which was processed by other persons without any errors. That was one of the reasons I decided to update...
I feel like I'm going crazy and don't know what to do. Any constructive idea is much appreciated.
