Superscripts and rounding
I am new to the world of R/programming so this may be a really easy question.
I thank you for your patience and help in advance
I would like the characters km^2 to be displayed on the plot subtitle as km
squared - two as a superscript.
I would also like to have the numbers from the data set for longitude and
latitude to be rounded to four decimal places.
Thank you.

I would like to be able to parse this file up:
I can do this
x <- read.table("http://waterdata.usgs.gov/nwis/uv?format=rdb&period=7&site_no=021973269",
skip=26)
but If I add another gauge to this

USGS stream flow data automatic download R
I don't even know if this is the right place to ask this question. I
would like to download USGS stream gauging data for a couple of gauges
on a daily basis- save the files to .csv files and append the nest
days time series to this. Is there a way to do this automatically in
R?
thanks,

pulling recessions out of a hydrograph
Dear R community,
I'm hoping someone out there has perhaps done this and can share their code
and/or expertise with me.
I need to pull recession periods out of a hydrograph - can anyone help me
with this?
I want to create a subset from streamflow data that consists of just the
recession curves - the decreasing runoff after the passage of a peak flow.
would really appreciate any help on

Limited number of principal components in PCA
Hi all,
I am attempting to run PCA on a matrix (nrow=66, ncol=84) using 'prcomp'
(stats package). My data (referred to as 'Q' in the code below) are
separate river streamflow gaging stations (columns) and peak instantaneous
discharge (rows). I am attempting to use PCA to identify regions of that
vary together.
I am entering the following command:

Boxplot 5% and 95% quantile instead of 25% and 75%
Hi,
I'm new to the whole R-thing as a replacement for Matlab, not disappointed sofar ;)
I found out how to make nice looking boxplots, but i also would like the make a boxplot with 5% and 95% instead of the standard 25 and 75% quantiles.
My csv input looks something like:

help in identifying the argument "formula" in the package nnet
hi everyone!
I have a 40-year monthy streamflow record. And i want to fit a neural
network. I already fitted an autoregressive model and found out that an
AR(3) model fits my time series (time.series) the best.
I am currently having problems on how to express the argument "formula" for
my neural network.. I am aware that my model should be Q(t) ~ Q(t-1) +
Q(t-2) + Q(t-3). But I

Timeseries Data Plotted as Monthly Boxplots
Hello, I'm trying to develop a box plot of time series data to look at the
range in the data values over the entire period of record.
My data initially starts out as a list of hourly data, and then I've been
using this code to make this data into the final ts array.
# Read in the station list
stn.list <- read.csv("/home/kbennett/fews/stnlist3", as.is=T, header=F)
