[R] line numbers and file names in error messages

Many of my R scripts call other R scripts using the source function. If there is a syntax error in one of the scripts, I get an error message such as Error in parse(file, n, text, prompt) : syntax error on line 1 but the name of the file where the error occurs is not given. Other error messages

[R] terminate R program when trying to access out-of-bounds array element?

[R] Why is 1 a double?

[R] static analysis tools for R code?

An R script will terminate when one tries to use an undefined variable, with a message such as Error in print(x) : Object x not found This run-time error might occur after the script has already been running for some time. In some cases it would be nice to get such warnings before the script is
