Possible to "import" histograms in R?
Hi,
I have a large amount of data that I would like to create a histogram of and
plot and do things with in R. It is pretty much impossible to read the data
into R, so I have written a program to bin the data and now have a list of
counts in each bin. Is it possible to somehow import this into R and use
hist(), so I can, for instance, plot the probability density? I have looked

Updating R-Software without complete new installation
Hallo,
as I see there is a new version for R available. Can anyone tell me how
I can update my version 2.5.0 under Windows? The last times I just
uninstalled the old version and installed the new one. Afterwards I had
to install also all needed packages again. All in all it cost me half a
day until my system works fine again. Is there a quicker option? If yes
please tell me the commands.
Thanks,

Fwd: Re: Calling C code from R
Hi!
Thanks in advance.
Thanks to all of you who have responded to me on above. This is one of the responses I received on above.
I have installed perl (with path C:\Perl\bin\;) an MinGW (with path C:\MinGW\bin; C:\MinGW;).
At the Command Prompt (C:\R-2.4.0\bin) I have typed:
C:\R-2.4.0\bin>Rcmd SHLIB useC1.c

how to image.plot a XY grid file into a lat-lon map
Hi All,
I have a netcdf gridded file with LCC projection. I can easily use
image.plot to visualize it. However, as the axises are in X,Y, not Lat and
Lon, I could not add state or country maps onto it (or lat lon information).
I do have a grid2d file that describes the lat and lon for each (X,Y) grid,
but the lat and lon are not regularly spaced, so I could not use image.plot.
Does anyone know

how to explore contents of R data file from command line?
Dear all,
I have a directory with my research project, containing files
.RData
and
inflow.RData
I am just curious, is there any way to explore contents of inflow.RData from
command line without affecting .RData and without copying inflow.RData to
another location?
I can see names and character attributes (of something in the file) in a 3rd
party raw file viewer.

looking for equivalent of matlab's medfilt1 function
Dear all,
I have several files with Matlab code, which I am translating to R.
For the zero-level approach, I took the very old shell script from R-help
archives, which has made some obvious leg-work such as replacement of "="
with "<-".
Now I am translating indexing, matrix operations and function call using

Please, remind a function name
Sorry, I'm stuck. :)
I am writing a function, which would fit either one linear model or another
one, depending on its argument model.type.
And I don't want to use several if's, because R allows doing it with much
more beauty.
That is I am looking for prettier alternative to the following
AB2C<-function(a,b,model.type="S") { # or HK, and return NULL if this
argument has

What is "print print print" ?
...the command by parts I also see the output.
If I construct the command by picking parts of the history with the up
arrow, I also don't see any output.
Search for "print print print" still didn't bring anything useful.

More simple implementation is slow.
Hi all.
I'm developing a function, which must return a square matrix.
Here is the code:
http://pastebin.com/THzEW9N7
These functions implement an analog of two embedded for cycles.
The first variant creates the resulting matrix by columns, cbind()-ing them
one by one.
The second variant creates the matrix with two columns, which rows contain
all possible
variants of i and j and calls apply

How to display an image on RGL plot?
Hi all.
It's been a long time since I wrote to this list. Glad to see the R project
well and working.
I am working with a 3D plot similar to this:

The underlying picture is a JPEG image, loaded with the rimage package and
coerced to the matrix.
Spheres denote control points, collected from this picture and must be

Partial comparison in string vector
Hi list members
I have a vector of strings
x=c("w","ex","ee")
And I want to get a logical vector showing the positions where my search
string "e" matches the elements partially, i.e. is at least the left-hand
part of the target strings, i.e. I want to get a vector FALSE TRUE TRUE.
Any ideas?
Thanks

how to exclude some packages from help.search() ?
I have installed RGTk2 to satisfy other package requirements.
I am not planning to use it in my own work.
Occasionally I search through the R help using the help.search() function,
and every time it returns me lots of references to the functions in the
RGtk2 package, which I don't need.
I would like to avoid them.
At present, I have renamed the file hsearch.rds in the RGtk2 directory.

private variables in package.
I am sorry, my previous questions about hiding variables from users in a
package were obscure and vague, and would like to clarify them.
This should be a basic question.
I am writing my first package.
It has several functions, which should be callable by users.
These functions use several variables, and I would like to hide these
variables from users.
How can I do it?

how to trace what crashes R
I am writing bindings to the C library (neural network simulator SNNS).
DLL was produced with the command
R CMD SHLIB [source with C-wrappers, callable from R with .C and all
sources from the snns kernel]
I used latest MinGW.
The problem is. R crashes with the "segmentation violation".
Tracing with the insight and with simple Rprintf's gave me that crash occurs
