Hi All,
I have problem to plot histogram.
What I did is:
export a .csv file from PSQL database's table.
so, inside this .csv file it looks like:
31.845
24.598
29.1223
24.715
23.1847
24.2321
25.2995
23.4261
30.7873
..
Then, I use command:
score- read.csv('file.csv', header = FALSE,sep = ,)

hist(score, main = score)
it gives error msg:
Error in hist.default(score, main = score) :
'x' must be numeric
Can any of you know about it explain me why?
Have a look at 'score' in R
