Usage

suppress_specific_warning(expr, pattern)

Arguments

expr: Expression to evaluate.
pattern: Regular expression used to identify warnings that should be suppressed.

Value

A list with two elements:

value - the result of evaluating expr
suppressed - a character vector of suppressed warning messages

Examples

suppress_specific_warning({
  warning("Ignore this one")
  123
}, pattern = "Ignore")
#> $value
#> [1] 123
#> 
#> $suppressed
#> [1] "Ignore this one"
#> 

# Suppress the usual "NAs introduced by coercion" warning
# and use $value to store the result and ignore the $suppressed component
