Superscript in y-axis of plot
Dear all,
I've been trying to superscript the '2' in the following command (I don't want the '^' displayed), but as yet haven't had much luck. I've tried both the paste and expression commands, but neither have brought me any joy!
mtext(side=2, line=5.5, "Monthly Precipitation (mm x 10^2/month)", font=2, cex=1.1)
Any advice would be much appreciated,

Plot frame border to start at zero?
Hello,
I am creating plots of hourly precipitation and accumulated
precipitation (on different axis, see attached image). I was wondering
how can I have the plot frame (black border) start at zero, it looks
like it is plotted less than zero?
The code I use to create the png files is below:
CairoPNG(PNG_file,width=1000, height=600, pointsize=14, bg="white")

mean of runoff for several years
Hello everyone
I have a dataframe with 4 colums (year, month, day, runoff) for 1993-2009.
Now I like to calculate the average runoff for each day. Finally I like to
plot the median runoff for all this years.
I tried with some loops, but it didn't work. Do you have any Tips for my
problem?
Any help is greatly appreciated! Thank you very much.

master thesis
Hi,
For my master thesis I have 24 micro-plots on which I did measurements during 3 months.
The measurements were:
- Rainfall and runoff events throughout 3monts (runoff being dependant on the rainfall, a coefficient (%) has been made per rainfall event and per 3 months)
- Soil texture (3 different textures were differentiated)
- Slope (3 classes of slopes)
- Stoniness (one time measurement)

how to use "replace" for efficiency
Hi
I think I have been struggling to use replace correctly, I usually
work my way around this using a loop, but I think this is in fact
inefficient.
I have a dataset with runoff from three plots and associated rainfall.
However either the datarecording was sloppy, or the rainfall very
patchy. So I am trying to remove data from my dataset for which the
runoff is larger than the rainfall on the

Function that is giving me a headache- any help appreciated (automatic read )
note: whole function is below- I am sure I am doing something silly.
when I use it like USGS(input="precipitation") it is choking on the
precip.1 <- subset(DF, precipitation!="NA")
b <- ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum)
DF.precip <- precip.1
DF.precip$precipitation <- b$.data
part, but runs fine outside of the function:

Principal Component Analysis - Selecting components? + right choice?
Dear R gurus,
I have some climatic data for a region of the world. They are monthly averages
1950 -2000 of precipitation (12 months), minimum temperature (12 months),
maximum temperature (12 months). I have scaled them to 2 km x 2km cells, and
I have around 75,000 cells.
I need to feed them into a statistical model as co-variates, to use them to
predict a response variable.

Color scale graphic
Hello
Recently, I've been dealing with a seemingly simple problem. I have a table
with two columns filled with values from a test I made (say, amount of
precipitation and Months measured). Now, instead of plotting a typical
linear graphic with precipitation on the y-axis and the months in the
x-axys, I would like to "convert" the values of precipitation in a color
gradient,

using complete.cases() with nested factors
Hello,
This maybe a newbie question. I have a dataframe that looks like the sample
at the bottom of the email. I have monthly precipitation data from several
sites over several years. For each site, I need to extract years that have
a complete series of 12 monthly precipitation values, while excluding that
year for sites with incomplete data. I can't figure out how to do this

option to control the spac between columns in data frame
Hello,
I have a question regarding a way to control the appreance of output
exported by R
when I use capture.output( x, file = "Directory/file.txt") , I get a text
file which when I paste to a word file looks like the first table below.
The following table has its clumns spaced closely so when I paste it to a
word file it looks continuous. Is there any option in R to make the outputs

Extract, sum and Loop in R
Hi all,
I have gone through some basics of R in eclipse environment. What I need to
work is more than basic level so I could not find out the solution by
myself. could anyone help me ?
My case,
I have climate data (precipitation) in nc format with single layer for each
time interval in a day. That means for January 1, 2013, I have 8 separate
files each containing 3 hrs cumulative precipitation

Sum per hour
Dear all,
I have a list of precipitation record and a list of time
I would like to sum them up per hour, or per day.
Does such a function exist ?
example:
time<-c("2000-10-03 14:00:00","2000-10-03 14:10:00","2000-10-03
14:20:00","2000-10-03 15:30:00","2000-10-03 16:40:00","2000-10-03

count length of continues elements in a vector
I am performing a precipitation analysis. data is in the form of daily
precipitation amounts, e.g.
x<- c(4,5,3,0,0,0,2,4,6,4,0,0,0,2,2,0,3,4,1,0,...)
I would like to find the length of the "storm", length of storm would be
defined as the number of days with continues precipitation. in this case the
returned vector would be:
(3,4,2,3,...)
I would also like the amount of

value of nth percentile
Dear All,
I have to get the value of say 90th percentile of precipitation time series.. The series is of daily precipitation value of 96 years, I have to to get 90the percentile value of daily precipitation each year. If you know the R code or command for this please let me know.
I would appreciate your early response.
Thanking you,
Sincerely,

Working with duplicated rows
Dear all,
I have a dataframe of 3 columns, consisting of 'longitude', 'latitude'
and a corresponding 'value'. Where identical 'longitude' and 'latitude'
pairs occur more than once, I want their corresponding 'value' to be
summed and the 'pair' to only appear once.

spgrass6 and aggregation (bis)
Dear all,
I have some additionale question concerning the spgrass6 package.
* When you set a region in GRASS, does the readGRASS6 function in R only
load data contained in the zoomed region or the whole map ?
* When you have a MASK map in grass, does the readGRASS6 function in R only
load data contained inside the MASK area ?
Could this be the problem ?
Thanks,
Jessica
