I tried to read a dataset and then draw a histogram with a freqeuncy density curve fitted on the top of this. I used the command

res <- read.table("C:/Documents and Settings/db/Desktop/res.dat") and found
> res[1:5]
       V1     V2     V3      V4     V5
1 -0.4806 0.5075 0.0491 -0.7985 -0.666
Then I got the following when I troied to plot it
> hist(res) 

Error in hist.default(res) : 'x' must be numeric

Even I tried
> hist(res[,2])
which is showing a blank plot.
My suspision is something is wrong in the way the data was read (with V1, V2, V3 etc). Can someone  please help me how to get rid of this problem ?
