问题:
I had everything working with R and RStudio, but then I moved the folders when cleaning up my computer directories & files. Now I'm getting the error message below.
Should R and RStudio be installed under Program Files or Program Files (x86)? Should I have two libPaths?
install.packages("C:/Users/kevin/Downloads/fpp_0.5.zip", repos = NULL) ## Warning in install.packages : ## package ‘C:/Users/kevin/Downloads/fpp_0.5.zip’ ## is not available (for R version 3.0.0) ## Installing package into ‘C:/Users/kevin/Documents/R/win-library/3.0’ ## (as ‘lib’ is unspecified) ## package ‘fpp’ successfully unpacked and MD5 sums checked library("fpp", lib.loc="C:/Users/kevin/Documents/R/win-library/3.0") Loading required package: forecast ## Error in loadNamespace(j
回答1:
When you install the package using the RStudio package installer or directly from CRAN, it doesn't install the dependencies ("fracdiff", "Rcpp", "RcppArmadillo" and "colorspace") and hence, R keeps throwing the load namespace error. Installing the package through, automatically installs all the dependencies and solves this problem.
install.packages("forecast", repos = c("http://rstudio.org/_packages", "http://cran.rstudio.com"))

The last time I encountered a very similar problem, I used this code which I got somewhere: install.packages("package's name", repos=c("http://rstudio.org/_packages", "http://cran.rstudio.com")) simply put your package's name in the quotation marks. Hope this helps.

Use this:
install.packages("colorspace", dependencies = TRUE)

I ran into this problem. It turned out that my .Rprofile had calls to a package that was not installed. Removing these lines allowed installation to proceed normally.
