[R] "Levels" error after printing

[Gundala Viswanath]

Hi all,

After running this code (attaches is the input file):

dat <- read.table("gene_prob.txt", sep = "\t")
n <- length(dat$V1)
print(n)
print(dat$V1)

I get this print out.

......
[8541] LOC552889     GPR15         SLC2A11       GRIP2         SGEF
[8546] PIK3IP1       RPS27         AQP7
8548 Levels: 3.8-1 A2M A4GALT A4GNT AAAS AAK1 AAMP AANAT AARSD1 AASS
... hCG_1730474

What's the meaning of the last line? Is it an error?
