Replace_Missing(df, name_list, msv, verbose = FALSE)

Value

returns a filled datatable

Arguments

df

a data.table containing the columns of interest

name_list

vector of string column names to check

verbose

integer valued 0-4 controlling what information is printed to the terminal. Each level includes the lower levels. 0: silent, 1: errors printed, 2: warnings printed, 3: notes printed, 4: debug information printed.

The default level is 2 and True/False is converted to 3/0.
