Hello All,

I have a data with two columns. In one column it is date and in another
column it is flow data.

I was able to read the data as date and flow data. I used the following
code:

creek <- read.csv("creek.csv")
library(ggplot2)
creek[1:10,]
colnames(creek) <- c("date","flow")
creek$date <- as.Date(creek$date, "%m/%d/%Y")

The link to my data is https://www.dropbox.com/s/eqpena3nk82x67e/creek.csv

Now, I want to find the summary of each year. I want to especially know
mean, median, maximum etc.

Thanks.

Janesh
