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/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 ? ?
