lib unspecified & Error in loadNamespace

Question

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.

Answer 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"))

Answer 2

I got this error while installing the library 'tidyverse'. Removed the error by upgrading R from v3.4 to v3.6

Answer 3

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.

Answer 4

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.

Answer 5

Use this:

install.packages("colorspace", dependencies = TRUE)
