Problem during install

[fuxj]

Hi All,

When I install, I get the erro information like this:

Error in unloadNamespace(package) :
namespace ‘Rcpp’ is imported by ‘scales’, ‘reshape2’, ‘plyr’, ‘minqa’ so cannot be unloaded
Error in library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc, :
Package ‘Rcpp’ version 0.12.2 cannot be unloaded
ERROR: lazy loading failed for package ‘RRegrs’

• removing ‘/Users/fuxianjun/Library/R/3.2/library/RRegrs’

How can I resolve it?

Any advice would be greatly appreciated.

hi,

please update R and related packages before trying to install RRegrs. In the DESCRIPTION file, lazy load is set to true.

Hi Carlos,

Many thanks for your comments. I tried updated the R and all the packages:
platform x86_64-apple-darwin13.4.0
arch x86_64
os darwin13.4.0
system x86_64, darwin13.4.0
status
major 3
minor 2.3
year 2015
month 12
day 10
svn rev 69752
language R
version.string R version 3.2.3 (2015-12-10)
nickname Wooden Christmas-Tree

But the errors remain appeared like this:

• installing source package ‘RRegrs’ ...
  ** R
  ** inst
  ** tests
  ** preparing package for lazy loading
  Note: the specification for S3 class “family” in package ‘MatrixModels’ seems equivalent to one from package ‘lme4’: not turning on duplicate class definitions for this class.
  Error in unloadNamespace(package) :
  namespace ‘Rcpp’ is imported by ‘scales’, ‘reshape2’, ‘plyr’, ‘minqa’ so cannot be unloaded
  Error in library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc, :
  Package ‘Rcpp’ version 0.12.2 cannot be unloaded
  ERROR: lazy loading failed for package ‘RRegrs’
• removing ‘/Users/fuxianjun/Library/R/3.2/library/RRegrs’

So could you please inform me where the problem lie.

Best,

Xianjun

Dear Xianjun,

I performed a clean install of RRegrs without problems using the README steps, it seems that this is not a problem directly related with the RRegrs package installation. So please, try to perform a clean install.

Dear Carlos,
I really appreciate your suggestion and help. I am sorry but I tried but failed yet. Maybe something wrong with my system. I will continue to try and find out where it wrong.
Thanks again,
Best,

Xianjun, can you maybe have a look at this similar report: r-lib/devtools#886

There they also have trouble with unloading Rcpp... does that look similar to you?

That report suggests we may want to play the order in which we depend/require packages.

Hi Egon,

Many thinks, I will look and try.

For the next release, we may want to import specific methods, rather than full packages. See issue #4

I just went to the packages tab and clicked update. Selected all suggested updates and updated all and viola it worked.
