Hmisc not loading with UsingR #68

Closed davemc528 closed 7 years ago

davemc528 commented 7 years ago

I'm working through Using R for Introductory Statistics, and whenever I try and load the UsingR package I get this error:

install.packages("UsingR") trying URL 'https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.3/UsingR_2.0-5.tgz' Content type 'application/x-gzip' length 2043639 bytes (1.9 MB)

downloaded 1.9 MB

The downloaded binary packages are in /var/folders/5q/m7kmn4gs7pq_5yk42ldrckvc0000gn/T//Rtmp6ONqNe/downloaded_packages

require(UsingR) Loading required package: UsingR Loading required package: Hmisc Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ‘data.table’ Failed with error: ‘package ‘Hmisc’ could not be loaded’

Any help would be appreciated.

I'm not the primary maintainer, but I think Hmisc requires the data.table package. Not sure why it wouldn't be installed as well, but try install.packages('data.table').
