Rcpp package and Forecast package issues (old versions)

问题

I have two linux machines with R version 3.0.0

I've installed the forecast package version 4.8 on both machines.

Both machines have the same version of dependencies :

>ip <- installed.packages()
>ip[c("forecast","Rcpp","RcppArmadillo"),c("Package","Version")]
              Package         Version
forecast      "forecast"      "4.8"
Rcpp          "Rcpp"          "0.10.2"
RcppArmadillo "RcppArmadillo" "0.4.000.4"

But when I run it on the other node I get the following error :

>library(forecast)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
  namespace ‘Rcpp’ 0.10.2 is already loaded, but >= 0.11.0 is required
Error: package or namespace load failed for ‘forecast’

These R versions are a little old because they are used in Vertica's 'R language pack' in which I can't upgrade the version and the Rcpp package.

How can I solve this or research the problem further?

回答1:

Maybe you need to talk to Vertica?

In short, do one of these things:

go with your vendor, and stick to old versions (which is bad: R 3.0.0 has been superseded by 3.0.1 and 3.0.2 with 3.0.3 coming out next week; Rcpp 0.10.2 is ancient, we are at 0.11.0 now);
update your packages, but make sure yo do it in lockstep (ie use the Rcpp version that was current when your version of forecast was built -- which you currently violate using a version that need Rcpp 0.11.0 when you only have Rcpp 0.10.2 [ very old !! ];
ignore your vendor and update in a local library, pre-pend the .libPaths() (see help(Startup) for details)

Lastly, if I may, I find the title of your question misleading. I'd say the error is due to your installation of non-matching version onto your base R (from Vertica). The packages Rcpp, RcppArmadillo and forecast all work just fine in a normal environment.
