You should look at the data that you imported to R from somewhere else with the str() or summary() function. Since you think the data should have nice column names but seems to have the names V1, ..., Vn, I think that you may may have read a file with column names at the top into R with read.table without specifying header=TRUE. With header=FALSE, the names will cause read.table to think that the column contains character data and header=FALSE also causes the column names to be V1, ..., Vn.
E.g., > dataText <- "ColA ColB\n1 100\n2 200\n" > str(read.table(text=dataText)) 'data.frame': 3 obs. of 2 variables: $ V1: Factor w/ 3 levels "1","2","ColA": 3 1 2 $ V2: Factor w/ 3 levels "100","200","ColB": 3 1 2 > str(read.table(text=dataText, header=TRUE)) 'data.frame': 2 obs. of 2 variables: $ ColA: int 1 2 $ ColB: int 100 200 Again, use str() and summary() (or some of Hadley's tools) to make sure what you read into R is what you think it is. Also, make some simple plots of the data, say with pairs(). Do this before fitting any serious models to it.
