[R] colnames from read.table

[Chua Siang Li]

   Hi.  May I know why the colnames is NULL when reading only 1 column from a
   csv file?  How do I get the colname then? Thanks.
   > xy = read.table("dataFile.csv",header=T, sep=",")
   > y <- xy[,1]
   > xDate <- xy[,2]
   > x <- xy[,3:8]
   > colnames(y)
   NULL
   > colnames(xDate)
   NULL
   > colnames(x)
   [1]    "Market.Price"    "Quantity"        "Country"        "Incoterm"
