Hi there,

I am trying to use the DEP package and want to impute my data so that invalid values become 1. Is there an option to impute NA values to a constant (say 1)?

I typed impute(data_norm, fun = "") and it gives a message saying

Error in match.arg(fun): 'arg' should be one of "bpca", "knn", "QRILC", "MLE", "MinDet", "MinProb", "man", "min", "zero", "mixed", "nbavg"

```

But there doesn't seem to be any information on what these 'arg' are and how to use them in the code, apart from the 3 examples given.

If I can't make invalid values 1, how do I make them zero? I tried data_imp <- impute(data_norm, fun = "zero") and no error or warning message came up but when I continued with the next script there was an error message saying that my data had missing values.
