I am trying to run this rcmndr plugin for my class and it's not working. I installed all the necessary packages and it appeared to install correctly but I am getting this package or namespace load failure. The GUI appears for a split second when I enter the library command, then disappears with the error. It seems to be an issue with the namespace and .onattach but I couldn't find any existing answers or resources for this issue.

    What is your R version? – nrussell Dec 29 '15 at 18:45
  • Do you have pkg:RODBC and needed dependencies installed? (It's not on CRAN for Mavericks+ versions of OSX.) – IRTFM Dec 29 '15 at 22:42
  • I updated R to 3.2.3 and installed the RODBC package. Still getting same errors. Any idea what the .onattach/namespace issue is about? – Shawn Jan 04 '16 at 00:36
  • There are multiple package dependencies for RcmdrPlugin.BCA. Have you checked that they are all met. I was able to install but not able to load that package in a current version of R Rcmdr and OSX. I am asked if I want to load and restart Rcmdr and what I pick 'restart' I get an error at the R console. I'm a command-line user of R, not a menu pulldown-user, so this doesn't bother me. – IRTFM Mar 09 '16 at 01:49

I got alternative to run this plugin in R commander. Open R Commander by using:

library(Rcmdr)

R Commander dialogue box will appear. In R Script load BCA library-

lapply(list('BCA', 'splines', 'RcmdrMisc', 'car', 'sandwich', 'flexclust', 'grid','lattice','modeltools','stats4','RODBC'), require, character.only = TRUE)

Click on Submit button. If you don't have RODBC package (which is not there in my case), install it separately and then run above commands. To install use:

install.packages("RODBC")

And now you exactly have what you will get after loading RcmdrPlugin.BCA library.

I faced a similar situation. Having tried a bunch of things - none worked - I finally uninstalled R and deleted the remaining files from under the "Program Files" directory in Windows. I then reinstalled R and RcmdrPlugin.BCA and this time it worked.
