Why is the "epicalc" package removed from CRAN?

Question

Follow this link:

https://cran.r-project.org/web/packages/epicalc/index.html

You will receive a message:

Package 'epicalc' was removed from the CRAN repository. Formerly available versions can be obtained from the archive. Archived on 2015-05-12 as requested by the maintainer < [e-mail] >. 

But no further explanation is given. This seems like well-designed and useful packages, so why was it removed?

Answer 1

It seems that the material from epicalc been moved to epiDisplay .

epiDisplay package info says:

A package for researching data and presenting results. The full "epicalc" package with data management features is available in the author's repository.

(although it does not provide a link).

 devtools::install_version("epicalc",version="2.15.1.0") install.packages("epiDisplay") library("epicalc") library("epiDisplay") c1 <- ls("package:epicalc") d1 <- ls("package:epiDisplay") 

In epicalc , but not epiDisplay :

 setdiff(c1,d1) ## [1] "addMissingRecords" "adjust" "auc" ## [4] "be2ad" "detachAllData" "expand" ## [7] "fillin" "keepData" "label.var" ## [10] "lagVar" "markVisits" "merge.lab" ## [13] "pack" "print.summ" "recode" ## [16] "recode.default" "recode.is.na" "ren" ## [19] "rename" "rename.default" "rename.pattern" ## [22] "rename.var" "sortBy" "tally.events" ## [25] "unclassDataframe" "use" "zap" 

In epiDisplay , but not epicalc :

 setdiff(d1,c1) ## [1] "print.summ.data.frame" "print.summ.default" "summ.data.frame" ## [4] "summ.default" "summ.factor" "summ.logical"
