问题
I was developing a package when I found a new error when building the package.The error makes reference to a line that previously didn't have any problem and I didn't modify. However it run smoothly in a fresh R session when I ran the code or knit the vignette alone.
Long story short: I found that this error happens when a suggested package (by my package's DESCRIPTION) is loaded before my package.
How can I control this?
The reason of the error is that my package (A) has a function is named exactly the same as the other package (B) because it does the same kind of process, but I use a different name for the same arguments (and in my version I provide other arguments as well). A solution I found is to use A::function, but that would be uglier to the reader. Is there any other solution?
This didn't happened in previous cycles of development. I have observed it on the latest R version R version 3.4.3 (2017-11-30) -- "Kite-Eating Tree" and in the devel version of R. The packages are build using both R CMD build package and devtools::check()
The conflicting package is in Suggests: part of the DESCRIPTION file of the package
This question might be related to this other one.
