> x [1] structure(c("GO:0004707", "GO:0005524", "GO:0004674", "GO:0006468", "GO:0000074", "GO:0008372", "GO:0016740"), .Names = c("NAS", "NAS", "IEA", "IDA", "NAS", "ND", "IEA")) 6204 Levels: GO:0000074 GO:0000158 GO:0000163 GO:0000166 ... structure(c("GO:0019538", "GO:0016706"), .Names = c("IEA", "IEA")) > parse(text=x) #a failed attempt expression(2287) > eval(parse(text=x)) [1] 2287 > Any idea? By the way why does parse return 2287?
