save to file
Hi,
What's the equivalent of "Save to File" from the R console File menu on an R routine? Just trying
to capture the whole R console into a text file when my code fails.

another question on shapefiles and geom_point in ggplot2
Manuel:
I changed your variable names from x to 'long' and y to 'lat' on the
riqueza_out.csv file.
The code below should do what you want. Also, since the legend title is kind of
long, I broke it
down into three lines so you can see more plot area. I am cc'ing the other
groups so more people
use it if needed.
library(rgdal)
library(ggplot2)
library(sp)

arrange data
Dear r-users,
I have daily rainfall data from 1971 to 2000. I would like to extract november and december data only. I would also like to do column bind for november and december, therefore I would like to delete 31 December from december data so that the length of november and december are the same. Hope somebody can help me. I tried this below:

nls question
Hi:
Using nls how can I increase the numbers of iterations to go beyond 50.
I just want to be able to predict for the last two weeks of the year.
This is what I have:
weight_random <- runif(50,1,24)
weight <- sort(weight_random);weight
weightData <- data.frame(weight,week=1:50)
weightData
plot(weight ~ week, weightData)
M_model <- nls(weight ~ alpha +

apply is slower than for loop?
I thought the "apply" functions are faster than for loops, but my most
recent test shows that apply actually takes a significantly longer than a
for loop. Am I missing something?
It doesn't matter much if I do column wise calculations rather than row wise
## Example of how apply is SLOWER than for loop:
#rm(list=ls())
## DEFINE VARIABLES
mu=0.05 ; sigma=0.20 ; dt=.25 ; T=50 ;

replacing elements of a zoo object
Why doesn't this work?
x = zoo(1:5, as.Date('2001-01-01')+1:5)
x[as.Date('2001-01-05')]
x[as.Date('2001-01-05')] = 0
x
I think this is especially bad because it doesn't cause an error. It lets
you do something to x, but then you can't see x again to see what it did.

read.table performance
** Disclaimer: I'm looking for general suggestions **
I'm sorry, but can't send out the file I'm using, so there is no
reproducible example.
I'm using read.table and it's taking over 30 seconds to read a tiny file.
The strange thing is that it takes roughly the same amount of time if the
file is 100 times larger.
After re-reviewing the data Import / Export manual I think

ggplot2 - extracting values of smooth
Suppose that I'm working on Hadley's diamond dataset and I want to
review the relationship between price, colour and carat.
I might run the following:

#plot scatter and add some hex binning
q<-qplot(carat,price,data=diamonds, geom=c("hex"),

How to pass a list of parameters into a function
Does anyone know how to pass a list of parameters into a function?
for example:
somefun=function(x1,x2,x3,x4,x5,x6,x7,x8,x9){
ans=x1+x2+x3+x4+x5+x6+x7+x8+x9
return(ans)
}
somefun(1,2,3,4,5,6,7,8,9)
# I would like this to work:
temp=c(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9)
somefun(x1=1,x2=2,temp)
# OR I would like this to work:
temp=list(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9)

where did ggplot go?
This must be explained somewhere, but I've been searching for a couple of
hours and not found it.
What happened to ggplot? It appears to be missing on CRAN, except in the
archives.

Has ggplot2 replaced ggplot?
I was trying to run some examples and found that "pscontinuous" and "ggline"
are not part of ggplot2.

simple subset question
Hi,
Consider the small dataset below, I want to subset by two variables in
one line but it wont work...it works though if I subset separately. I have
to be missing something obvious that I did not realize before while using subset..

Zooming in to a ggplot (a sort of ylim, but ylim won't do)
Dear Helpers,
I wonder whether you might be able to help me. I have a plot composed of
ggplot (and a follow on geom_smooth call). I would like to restrict the
display range of the y axis to a smaller range, a sort of zooming onto a
region. I attempted to use ylim, but it will effect the range (i.e. effect
the geom_smooth call). Is there any way that I can save the results up to
geom_smooth call

The L Word
I've been wondering what L means in the R computing context, and was
wondering if someone could point me to a reference where I could read about
it, or tell me what it's called so that I can search for it myself. (L by
itself is a little too general for a search term).
I encounter it in strange places, most recently in the "save" documentation.

Possible to access a USB volume by name in windows
On the Mac it's pretty easy to get to a USB drive by name. For example the
following command works if you have a USB drive named "MYUSB"
setwd('/Volumes/MYUSB')
Is there a way to do the same thing in Windows (without knowing the drive
letter)?
Thanks!

Testing for arguments in a function
I don't understand how this function can subset by i when i is missing....
## My function:
myfun = function(vec, i){
ret = vec[i]
ret
}
## My data:
i = 10
vec = 1:100
## Expected input and behavior:
myfun(vec, i)
## Missing an argument, but error is not caught!
## How is subsetting even possible here???
myfun(vec)
Is there a way to check for missing function arguments, *and*

curve fitted ... how to retreive data
Dear R users,
I have now managed to fit the curve using the thin plate spline as follows:
library(mgcv)
b <- gam(y~s(x1,x2,k=100),data =dat)
vis.gam(b)
What I want now is to get the fitted data for y and copy it so that I use it for further analysis.
Many thanks in advance

ggplot - adding regression lines
Hi
I am using ggplot to overlay two regression lines on a scatter plot each
corresponding to a treatment group.
The default plot gives a different slope for each treatment group. However,
in some cases i want the lines to be parallel -ie no significant
interaction.
My code:
ggplot(data=df,X,Y,colour=treatment) + geom_point() +
geom_smooth(method="lm")
I think i use the
