function naming conflicts

Question

What are some good patterns for development with packages that define the same function? In my case, lubridate and data.table both define wda

Answer 1

You can use ::, it helps to specify which package to use:

lubridate::wday
function (x, label = FALSE, abbr = TRUE) 
UseMethod("wday")


data.table::wday
function (x) 
as.POSIXlt(x)$wday + 1L
