Hi everyone,
I have certain values retrieved from mysql database.How can i do
certain analysis like histogram, correlational analysis tc using this data,I
tried it. But when i tried to plot a histogram it actually showed error the
data is not numeric evenif it was stored as integer data type in mysql db.
Please anyone help. Can anyone specify the steps for doing data analysis
after retrieving data
from the database.

Please tell us the package you are using and the specific commands. It is most likely you are retrieving the data into a list or some other structure that hist() doesn't like.

at least provide a sample of the data. It sounds like you have 'factors' as your data. Do an 'str' of your dataframe that was returned.
