Dear R group,
I was working on an example dataset to see if the row labels can be deleted.?? I
know that header=TRUE could be used when we use read.table.? In the data.frame,
I tried to delete row labels 1,2,..5, but so far not successful.? Is there a
neat way to do it.
Thanks.
A.K.
HousePriceT1<-structure(list(Price = c(52, 54, 57, 57, 59), Floor = c(111,
128, 101, 138, 93), Area = c(830, 710, 1000, 690, 780), Rooms = c(5,
5, 5, 5, 5), Age = c(5.2, 6.2, 3.8, 4.5, 6.8), Cent.heat = structure(c(1L,
1L, 1L, 1L, 2L), .Label = c("no", "yes"), class =
"factor")), .Names = c("Price",
"Floor", "Area", "Rooms", "Age",
"Cent.heat"), row.names = c(NA,
-5L), class = "data.frame")

Thanks Peter.? The code worked. I was trying to print it in the console without rownames.
