sorry about the change in variable name (data has column named usgs700 but
code has usgs700). actually i am trying to get familiar with R as i need to
make more complex time series plots in near future (stackplots, scatterplot
etc.). Let me try to explain what i am intending to achieve here. below i
have copied first few lines of a large dataset (daily flow records for 4017
days at 8 usgs locations). first column is date and rest of them are flow
data measured at these 8 different location. now all i wish to do is to read
them in and make time series plots for the entire period of record for each
stations. i have attached some figures that i made in excel and i wish to do
something like this using R.
I know my code might have some errors and that's the reason why i am
requesting for help from people who know R better than I do. i am R user for
less than a day but i know what i am trying to do is really simple and all i
need is to read 9 columns and make a simple time series plot.
i would appreciate if anyone can correct the code that i have written below
or if they have some alternate way of doing this i would be happy to learn
something new
regards
vibhava
