installing devtools and ez

[Robert Day]

Hi Mike,

I am very new to R, used Systat previously. 

Tried to install ez following your website advice, on my Mac with OSX 10.11.6

install.packages ("devtools") worked only with double quotes, and confirmed "package:devtools" present in workspace.

d> install_github("ez","mike-lawrence") worked until...

* installing *source* package ‘ez’ ...

** R

** data

** byte-compile and prepare package for lazy loading

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 

  there is no package called ‘pbkrtest’

ERROR: lazy loading failed for package ‘ez’

* removing ‘/Users/admin/R-dev/ez’

Error: Command failed (1)

I saw the code you gave John Shepherd some years ago, and tried that too. But search() revealed no ez package.

Am I missing something? Should ez or ezDev be accessed some other way?

Thanks in advance for your help

Rob
