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?
