Here's one way. Let's say I load the "glmnet" package, at the prompt I  
could use tab-completion to which functions are exported:

R> library(glmnet)
R> glmnet::<TAB><TAB>
glmnet::coef.glmnet      glmnet::jerr             glmnet::plot.glmnet
glmnet::predict.elnet    glmnet::predict.lognet   glmnet::print.glmnet
glmnet::glmnet           glmnet::nonzeroCoef      glmnet::plotCoef
glmnet::predict.glmnet   glmnet::predict.multnet

<TAB><TAB> is hitting the tab key twice in quick succession.

There are probably better ways, but there's one option.
