Convert data type of columns in DataFrame -- Object to float64

Post date: Aug 8, 2014 4:45:03 PM

Here is how:

## Originally, the type of df.raw_odr_rate is Object

df.raw_odr_rate.dtype

## And we want to convert it to numeric, more specifically float64

df.raw_odr_rate = df.raw_odr_rate.convert_objects(convert_numeric=True)
