force R to always display package name in error message
You can try conflict_prefer("summarize", "dplyr")
from conflicted package by Hadley Wickham. One drawback is that you need to identify winner for every conflict.
From the documentation of the base option error
:
'error': either a function or an expression governing the handling of non-catastrophic errors such as those generated by 'stop' as well as by signals and internally detected errors. If the option is a function, a call to that function, with no arguments, is generated as the expression. By default the option is not set: see 'stop' for the behaviour in that case. The functions 'dump.frames' and 'recover' provide alternatives that allow post-mortem debugging. Note that these need to specified as e.g. 'options(error = utils::recover)' in startup files such as '.Rprofile'.
So it should be possible to define a function that returns the name of the package where the function that’s throwing the error lives. For example:
library(dplyr)
library(Hmisc)
data(mtcars)
print_package <- function() {
calls <- sys.calls()
call <- calls[[length(calls) - 1]]
fun.name <- as.character(call)[1]
pkg.name <- sub("package:", "", getAnywhere(fun.name)$where[1], fixed = TRUE)
message (paste0("In ", pkg.name))
}
options(error = print_package)
summarize(mtcars$mpg)
Returns:
Error in summarize(mtcars$mpg) :
argument "by" is missing, with no default
In Hmisc
Edit (using rlang::trace_back
)
It turns out that there is a much cleaner way of doing this (credit goes to Hadley Wickham and his "Advanced R, Second edition"):
library(dplyr)
library(Hmisc)
data(mtcars)
print_trace_back <- function() {
print(rlang::trace_back(bottom = sys.frame(-1)))
}
options(error = print_trace_back)
Seems to handle errors gracefully:
> summarize(mtcars$mpg)
Error in summarize(mtcars$mpg) :
argument "by" is missing, with no default
