ENZYME2AFFY (now ENZYME2PROBE) is not a package but rather an environment in an 
annotation package for a given chip. To get the probe ids of hgu95av2 
corresponding to "" and "", for example, I would do 

> library(annotate) ## release version 
> library(hgu95av2)
> lookUp(c("", ""), "hgu95av2", "ENZYME2PROBE")
[1] "38528_at"   "31531_g_at" "31530_at"   "38529_at"  

[1] "1348_s_at" "37593_at"  "36561_at"
