Arguments

dt	[data.table()]
check_cols	[character()] name of columns in dt to check and modify.
is_fun	[⁠function()⁠] function like is.integer(), is.character() etc. to check if each of check_cols values evaluate to true. Default is is.integer().
as_fun	[⁠function()⁠] function like as.integer(), as.character() etc. to change column values to. Default is as.numeric().

Value

Modifies dt in place and returns dt invisibly.
