Hi,

I am trying to install mzR package.

But, when I set "library("mzR") I got Error message like below.

> library("mzR") # error
Loading required package: Rcpp
Error in unloadNamespace(package) :
namespace ‘Rcpp’ is imported by ‘scales’, ‘reshape2’, ‘readr’, ‘tibble’, ‘plyr’ so cannot be unloaded
Error in library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc, :
Package ‘Rcpp’ version 0.12.9 cannot be unloaded
> library("Rcpp")
Error in unloadNamespace(package) :
namespace ‘Rcpp’ is imported by ‘scales’, ‘reshape2’, ‘readr’, ‘tibble’, ‘plyr’ so cannot be unloaded
Error in library("Rcpp") :
Package ‘Rcpp’ version 0.12.9 cannot be unloaded

I have installed two packages ; mzR & Rcpp

But, I couldn't get the library from those packages.

Please let me know the way to solve this issue.

Thanks,

Junseok

Could you try the following in a new R session:

library("Rcpp")
library("mzR")
sesssionInfo()

and, if you encounter any errors, could you provide the full output of the session, including the output of sessionInfo().

Thanks, Gatto.

This is the output of those three commands.

> library("Rcpp")
Error in unloadNamespace(package) :
namespace ‘Rcpp’ is imported by ‘scales’, ‘reshape2’, ‘readr’, ‘tibble’, ‘plyr’ so cannot be unloaded
Error in library("Rcpp") :
Package ‘Rcpp’ version 0.12.9 cannot be unloaded
> library("mzR")

> sesssionInfo()
Error: could not find function "sesssionInfo"

Thanks,

Is this in a new session, i.e. you restarted R? If so, do you have an .Rprofile files that loads some packages automatically? To avoid anything like that, could you start R in a terminal with R --vanilla, then type the following:

ls()
sessionInfo()
library("Rccp")
library("mzR")
sessionInfo()

Note your type in sessionInfo!
