[julia-users] in-place substitution for an array?

[Douglas Bates]

This is trivial to write myself but I wanted to check that I am not missing 
an already-defined function.  I need to scan an Int32 array replacing all 
instances of typemin(Int32), which is the missing value sentinel used by R, 
with zero(Int32).  Is such substitution implemented by a function in Base?
