Arguments

df	data frame with original data
iv	list of information values for variables - output from iv.mult with summary=FALSE.
verbose	Prints additional details when TRUE. Useful mainly for debugging.

Examples

# Replace WoE for list of variables
outiv <- iv.mult(german_data,"gb",vars=c("ca_status","housing","duration"))
x <- iv.replace.woe(german_data,outiv)
str(x)

# Replace WoE for all variables
outiv <- iv.mult(german_data,"gb")
x <- iv.replace.woe(german_data,outiv)
str(x)

# Replace WoE for all numeric variables- ultimate one-liner
x <- iv.replace.woe(german_data,iv.mult(german_data,"gb",vars=varlist(german_data,"numeric")))
str(x)
