[BioC] how to convert gene identifier to symbol?

[Martin Morgan]

Hi Catherine --

One way:

> syms <- lapply(xx, mget, hgu95av2SYMBOL)
> unlist(syms[["00642"]])
  38377_at     840_at   31873_at   40782_at   35004_at   35203_at   39238_at 
   "MYST3"    "MYST3"    "ARD1A"    "DHRS3"    "DHRS2"    "MYST4"     "NAT6" 
  39691_at 39813_s_at 39814_s_at 39103_s_at   39104_at 
 "SH3GLB1"    "DHRS7"    "DHRS7"    "DHRS1"    "DHRS1"
