Error in recoding function from package epicalc

Question

I am trying to use recode function for demarcation of value in a variable but am not able to do so with a specific variable only where as it is working fine for another variable.

recode(age, age > 60, NA)

Error in recode.default(age, age > 60, NA) : object '.data' not found

What to do?

Answer 1

I think you could just do

age[age>60] <- NA

Note that epicalc is somewhat obsolete ... . It looks like epicalc operates by default on a data frame called .data , which could make things difficult ...
