unlist2: A replacement for unlist() that does not mangle the names

Description

unlist2 is a replacement for base::unlist() that does not mangle the names.

Usage

unlist2(x, recursive=TRUE, use.names=TRUE, what.names="inherited")

Arguments

x, recursive, use.names
See ?unlist.
what.names
"inherited" or "full".

Details

Use this function if you don't like the mangled names returned by the standard unlist function from the base package. Using unlist with annotation data is dangerous and it is highly recommended to use unlist2 instead.

Examples

Run this code
  x <- list(A=c(b=-4, 2, b=7), B=3:-1, c(a=1, a=-2), C=list(c(2:-1, d=55), e=99))
  unlist(x)
  unlist2(x)

  library(hgu95av2.db)
  egids <- c("10", "100", "1000")
  egids2pbids <- mget(egids, revmap(hgu95av2ENTREZID))
  egids2pbids

  unlist(egids2pbids)   # 1001, 1002, 10001 and 10002 are not real
                        # Entrez ids but are the result of unlist()
                        # mangling the names!

  unlist2(egids2pbids)  # much cleaner! yes the names are not unique
                        # but at least they are correct...
