Hello R users I have a dataset that has different types of records with different dates and times pertaining to each. I would like to have a bar graph of a count of the types(ie. The number of types) of recods by hour grouped by year. So the count of the types would be the y axis, the hour on the x axis and then grouped by year for easy comparison. I think that I have to use barchart however I don't know how to get barchart to do a count and not graph values. Thanks
