Modify base R functions in Rprofile.site
Hi everyone,
I want to modify two base R functions 'parse' and 'deparse'
immediately after R has started, so I added some code in the file
'Rprofile.site' under the 'etc' directory. Here is a simple example:
parse=function(...){
base::parse(...)
}
I'll get an error when I start R as follows:
Error: cannot change value of locked binding for

Writing R Scripts and passing command line arguments
Hi Guys
I am Abhishek, primarily a bioinformatician. I have recently started using
a lot of R thanks to some excellent packages available.
Lately I have felt the need to batch process few of the R scripts I have
been working with and strangely enough I am not able to find a good resource
on how to best do this. I did find few old threads on the archives but none
convinced me much. So here I am

Include files?
Hi,
I have 15 or 20 functions I've written to convert the sort of data
I'm working with. They are currently in their own R file which I load
by hand in Rgui before loading and running my main programs.
Is there any way to have this file included in my R program like
#include might in C?
If not is there a simple newbie-type example of how to create a
package so I could just say

Error on reading an excel file
Hello everybody, here is the code I use to read an excel file containing two
rows, one of date, the other of prices:
library(RODBC)
z <- odbcConnectExcel("SPX_HistoricalData.xls")
datas <- sqlFetch(z,"Sheet1")
close(z)
It works pretty well but the only thing is that the datas stop at row 7530
and I don?t know why datas is a data frame that contains 7531 rows with the

Sweave and backslashes

I am an avid Sweave user and I am trying to pretty print floating point

space in column name
I read a table from Microsoft Access using RODBC. Some of the variables had
a name with a space in it.
R has no problem with it but I do.

Incorrect positioning of raster images on Windows
I am working on dumping raster data from R into PNG files using
rasterImage(). I am working with a test matrix from the rasterImage()
example and using it to produce a PNG image with the following code:
# From the example for rasterImage(). A 3 pixel by 5 pixel b/w checkerboard.
testImage <- as.raster(0:1, nrow=3, ncol=5)

splitting dataframe, assign to new dataframe, add new rows to new dataframe
Hi, all,
My objective is to split a dataframe named "cmbine" according to the value of "classes". After the split, I will take the first instance from each class and bin them into a new dataframe, "df1". In the 2nd iteration, I will take the 2nd available instance and bin them into another new dataframe, "df2".

Curry: proposed new functional programming, er, function.
Hi all (especially R-core) I suppose,
With the introduction of the new functional programming functions into
base I thought I'd ask for a Curry() function. I use a simple one that
looks this:
Curry = function(FUN,...) { .orig = list(...);function(...)
do.call(FUN,c(.orig,list(...))) }
This comes in really handy when using say, heatmap():

Location of Packages?
Sorry, one more: on OSX, I deleted my old 2.9.2 R.app, and installed the 64
bit version of 2.9.0. I then did an "install.packages("car")" under my new
2.9.0. It seems to have worked, but alas, I still get an error that package
'car' was built under R version 2.9.2 . Where exactly does R under OSX
install its packages? (is it a bug that another car is loaded?)

Inconsistencies in device_Raster when axes are reflected
I noticed some undocumented and inconsistent behavior in device_Raster when a
plot is produced with reflected axes such as:
image(volcano, xlim = c(1,0), useRaster = TRUE)
image(volcano, ylim = c(1,0), useRaster = TRUE)
The `pdf` device will perform horizontal and vertical reflections, while
`quartz` will ignore the transformations when plotting to the screen, but

Rtools for building 64 bit windows packages
Hello R developers,
I sincerely apologize if the answer to this question is clearly documented
somewhere, but I was unable to figure it out over my morning coffee.
I just downloaded today's release of R 2.11.0 and installed it on my Windows
7 64 bit VM. I also downloaded the latest version of Rtools211 from
Professor Murdoch's site. The first thing I attempted to do was build some

R 2.13.0-beta for Windows, file.copy() throws suspicious errors due to default value of copy.mode
While checking packages against R 2.13.0-beta on Windows, I have run into a
few strange error messages related to copying files. The errors all relate
to file.copy() and have the form of:
Error in Sys.chmod(to[okay], file.info(from[okay])$mode, TRUE) :

with involves using

SSH Through R Script
Hi,
I am trying to SSH to a remote server through R script. In other words, I
would like to know how I can get a SSH connection to the remote server and
then execute commands on that server with the R script.
So in bash, I would normally type ssh -lusername remoteserver.com; press
enter and then wait for the password prompt to key in my password.
I have tried system("ssh

R to MATLAB translation
Hi,
Is there any package out there that might help me with translating R code
into MATLAB? Using RSiteSearch I found a bunch of "MATLAB stuff" but it
all seems to go in the opposite direction, i.e., emulating MATLAB
functions in R.
Thanks in advance,
Andy
