Dear All,
1.I have been trying to aggregate my data but I have not been getting it
correctly. In the data I want to convert hourly data into daily averages.
Here is a sample of the data:

2. I have some data of about 6100 rows and 6 columns, but anytime i read it
into R, it removes the header and a large chunk of the data.( i:e it will
import from row 3550-6099). This is the code i used for it
"met_data=read.csv(file.choose(),header=TRUE)", so, how do I read the
entire data into R without missing some?
Thank you.
