vim - Newer version of R does not load older packages -

i have issues regard package vimgui. trying use it, warning comes this:

loading required package: data.table error in load namespace(i, c(lib.loc, .libpaths()), versioncheck = vi[[i]]) :    there no package called ‘stringi’ in addition: warning messages: 1: package ‘vim’ built under r version 3.1.2  2: package ‘data.table’ built under r version 3.1.1  error: package ‘data.table’ not loaded 

when try install data.table error comes this:

package ‘data.table’ not available (for r version 3.1.0) 

if being told r 3.1.0 up-to-date using mirror year behind current version, you've been advised 3.2.0. furthermore current version of pkg:data.table 1.9.5 github , says requires "r >= 2.14.0" why mirror give error complete mystery. updates of r within minor versions (from 3.1.0 3.1.2 or 3.1.3 instance) painless , let avoid gentle warnings (notice: not error) such see such "package ‘vim’ built under r version 3.1.2".

i'm not seeing why data.table need vim or stringi matter. packages not in either improts or depends listing 'data.table'. i'm guessing there bunch of other code have not provided made failed attempt @ loading data.table-package.

update 3.1.3 (obtained more complete cran mirror appear using.) post output of sessioninfo() , maybe output of

(mypacks <- installed.packages()[ , 1:3]) 

that tell versions in library , whether have multiple libraries. wouldn't want post because me

 > nrow(mypacks)  [1] 1333 

but few packages installed, give complete listing of current versions , on drives. post:

mypacks[ mypacks[, 'package']  %in% c('data.table', 'stringi', 'vim') , ] ### output setup:            package      data.table "data.table" stringi    "stringi"    vim        "vim"                   libpath                                                          data.table "/library/frameworks/r.framework/versions/3.1/resources/library" stringi    "/library/frameworks/r.framework/versions/3.1/resources/library" vim        "/library/frameworks/r.framework/versions/3.1/resources/library"            version data.table "1.9.5" stringi    "0.4-1" vim        "4.0.0"
