Dear R users,
Can someone help me on this? I would like to find the sum of the Rain if
the Month appears more than once. For example in row 3 and 4, October
appear more than once, so I want to find the sum of the two rows and
replace it so that the Month just appear once. It some sort of merge
Maybe your answers are solutions, but not in my case.
As I indicated with my code-sample I don't have a complete tex-file
(with usepackage, document-env, etc). I only generate a piece of a tex
file to \input it later in my puplication tex-file.
So there is no way to specifiy an encoding with

Hi R-list,
I'm trying to fit a binomial GLM with user defined link function (negative
exponential), however I seem to be unable to find the correct starting values

Hello!
I recently finished a package that performs nonstationarity tests for large
panels and was wondering if anyone would be willing to read over the vignette I
wrote. The package uses the PANIC methodology from Bai and Ng (2004, 2010) and
is currently available on github. This is the first

I have written some gWidgets scripts before in the past but have a different
box now (Debian KWheezy) and cannot get gWidgets working. It may be an obvious
mistake but auntie Google (who has helped me a lot to get as far as I am now)
leaves me in the dark now.
Here is where I am stuck:

Hello,
Try
aggregate(Rain ~ Year + Month, data = dat, FUN = sum)
Hope this helps,

I am not taking this course for a grade, just self interest. I am stock with

Go to the HTML help for R and read An Introduction to R, section 10, Writing
your own functions (the clue's in the title). Don't miss out section 10.7,

I want to calculate water balance using the following formula:
Water balance today = Water balance yesterday + Rainfall − Evaporation
This is a sample of data I am using:

I am trying to get the current price of gold for my application. I am
using the library quantmod. The
R commands I use are:
getMetals(c('XAU'), from=Sys.Date(), autoassign = FALSE )
XAUUSD$XAU.USD[1,1]
I would expect the value in XAUUSD$XAU.USD[1,1] to be a scalar but it
comes back

Dear Duncan,
Those condition should be there and also look at Rainfall and evaporation
columns.
If i change it to be like the following loop, it can't do it.
The problem is how to include those conditions and also respect the formula?
wb=c()
for (w in 1:length(Wb30$Water_Balance)){
if(w0){
Counting chickens after they have left the coop is not going to work. If your
inputs push w outside the limits of physics then your input data are invalid.
Arbitrarily forcing w to fit in that case partially ignores the inputs
anyway... and since there are many ways for the data to be invalid
Sorry... That last expression was backward...
Wb30$ValidWB - with( Wb30, 0 == cumsum( Water_Balance 0 | 100
Water_Balance ) )

I am using R and quantmod to get stock and option quotes. However, it
has stopped working. I expect the following
function call to produce a list of options:
getOptionChain( XOM, Exp = 2015-01-20 )
However, I get the following error messages:

Hello List,
I have a database which consist of 912 plots. For each plot, I have the
presence/absence information of 260 species of plants and also 5 different
environmental variables (ddeg, mind, srad, slp, topo).
The dataframe looks like this:

Hello,
Yes, you can use lapply. Maybe something like the following. Note that
the result is a list with one member per species. (Untested).
ddeg.correlog.list - lapply(9:11, function(p)
correlog(plant[plant[,p]==1, 2], plant[plant[,p]==1, 3],
plant[plant[,p]==1, 4]))
Hope this helps,
If I understand the problem correctly, then I’d suggest this:
ndays - nrow(Wb30)
for (iday in 2:ndays) {
Wb30$Water_Balance[iday] - Wb30$Water_Balance[iday-1] +
Wb30$Rainfall[iday] - Wb30$Evaporation[iday]
Wb30$Water_Balance[iday] - min(Wb30$Water_Balance[iday], 100)
Perhaps this is a permissions (Xauthority) issue: is the same user running
both the X11 display and the R session?

All files have the same structure, after importing them I do few

Hi All,
This isn't a request for help. I just wanted to post that we've recently
completed a new package for R which allows you to do Open Street Map

It's not on CRAN (yet), but it is on Github.

i have a short question. Maybe anyone can help me to create a barplot in R with

A very limited set of attachment types are allowed on this list.. yours was not
one of them. Reading the Posting Guide will inform you about many useful things.
Self-contained R code is the expected mode of communication here.
From your description, you might consider monotonic spline fitting
Hi Ken,
Many thanks for your advice.
Earlier this morning I stepped my way through the glm.fit function to see where
things were falling over and realised that first and foremost I had my link
function wrong (link and inverse were back to front). I've now fixed this and
can get the model to
Dear usRers,
Now i want to cal ,e.g.

But the difficult part is cal(1.3450) will get 4 not 3.
So, is there anyone happen to know the solution to this problem, or it can't be
solved in R, because 1.340 will always be

Michael, thanks, that was it!
I had installed the packages as root and tried them out as root (not a good
idea I know, but I was lazy), while running the the X11 display as user.
Worse is that I have done that many times. One more thing learned.
Thanks again,
