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 ?
?
