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?
Thanks a lot.
.
