wrapr::let()
is designed to get several important corner cases correct:
including substitutions that are disjoint from the expression and symbol swaps.
library("wrapr") X <- 1 Y <- 2 let( c(), debugPrint = TRUE, X + Y ) let( c(), debugPrint = TRUE, subsMethod = 'langsubs', X + Y ) let( c(), debugPrint = TRUE, subsMethod = 'stringsubs', X + Y ) let( c(), debugPrint = TRUE, subsMethod = 'subsubs', X + Y )
library("wrapr") X <- 1 Y <- 2 let( c(X='Y', Y='X'), debugPrint = TRUE, X + Y ) let( c(X='Y', Y='X'), debugPrint = TRUE, subsMethod = 'langsubs', X + Y ) let( c(X='Y', Y='X'), debugPrint = TRUE, subsMethod = 'stringsubs', X + Y ) let( c(X='Y', Y='X'), debugPrint = TRUE, subsMethod = 'subsubs', X + Y )
