R: 2 functions with the same name in 2 different packages

Question

I need to load to R packages : tseries and chron

Both have a function named is.weekend

I always have in my environment the function from the second package I

Answer 1

you should turn to the conflicted package from Hadly.

library(conflicted)
library(dplyr)
filter(mtcars, am & cyl == 8)

Then the conflicted package will throw an error and will force you clearly determine which function you prefer:

Error: filter found in 2 packages. You must indicate which one you want with :: * dplyr::filter * stats::filter

To resolve conflicts for your entire session, use <-:

filter <- dplyr::filter
filter(mtcars, am & cyl == 8)

    mpg cyl disp  hp drat   wt qsec vs am gear carb
1 15.8   8  351 264 4.22 3.17 14.5  0  1    5    4
2 15.0   8  301 335 3.54 3.57 14.6  0  1    5    8

You can also turn to the conflict_prefer() function which can determine the winner when a conflict occur. The code example is borrowed from Hadly, pls refer to the package website. https://www.tidyverse.org/blog/2018/06/conflicted/
