r - Is this a function shadowing error? -


nothing applicable came in search, ran error when installing package in r:

> install.packages("entropy") loading required package: stats  attaching package: ‘zoo’  following objects masked ‘package:base’:      as.date, as.date.numeric  error in eval(expr, envir, enclos) : not find function "data.table" calls: source -> withvisible -> eval -> eval execution halted warning in install.packages :   installation of package ‘entropy’ had non-zero exit status

now, had data.table loaded in running session. when ran r session root , installed package no new packages loaded, finished no errors, , can load package initial session no problem.

where error coming from, , going give me possible bad output if have data.table loaded @ same time?
