Apologies if this sounds too opinionated, but creating variable names from variable values is a FAQ in a different dynamic language: https://perldoc.perl.org/perlfaq7#How-can-I-use-a-variable-as-a-variable-name? Most of the explanation doesn't apply to R, of course, but the main idea here is to use data structures instead of causing (potential, unlikely, but still) conflicts in the variable namespace. What if you create a list of function values instead of just a bunch of variables? results <- list() for(i in 1:nrow(datatable)) { val <- datatable$column[i] results[[as.character(val)]] <- my_function(val) } Or even results <- lapply(setNames(nm = datatable$column), my_function) Wouldn't that be more convenient?
