I have a R Package. It is working, but I can't that it install the

lattice::xyplot/ggplot2: plotting weighted data frames with lmline and smooth
In the HistData package, I have a data frame, PearsonLee, containing
observations on heights of parent and child, in weighted form:

'data.frame': 746 obs. of 6 variables:
$ child : num 59.5 59.5 59.5 60.5 60.5 61.5 61.5 61.5 61.5 61.5 ...

plotting a set of discrete distributions
I have the following data set, representing the the estimated number of
some event (est), when the actual number
was 3, 4, ..., 15. The numbers in the cells are the observed
*frequencies* of each combination of (actual, estimated),
so each column (a3 -- a15) gives a single discrete frequency
distribution. Thus, when the actual number was 6,
the estimated values were 5,6,7 with frequencies 7,

display SVG, PNG, GIF, JPEG, TIFF, PPM in new plot frame
Dear R-help
I want to display an image file in a new plot frame.
SVG is my preferred format, but I can also consider
PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick).
By way of background (although not material to this
posting), the image file is generated by a call to
'dot' (part of the 'Graphviz' suite) after the required
.dot file has been produced using hand-crafted R code.

Análisis de imágenes en R
Buenas dias a tod@s,
Quisiera saber si alguien tiene experiencia con el procesamiento de imágenes
(en formatos JPEG o PNG) en R y la búsqueda de similitudes / diferencias
entre ellas.
La idea de lo que me gustaría hacer es: tomar una imagen, cargarla en R y
luego analizar su estructura. Para las dos primeras tareas, la
libreria ReadImages en CRAN me ha sido útil, pero para la segunda, hasta

Weird errors with R CMD check/ggplot2 in examples: how to debug?
[Environment: WinXp, R 2.9.2, all packages up to date; building under

I'm in the process of creating a package, HistData, on R-forge,

several examples that use ggplot2,

package ReadImages
Dear all
I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix.
Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0.
What options I have now to import image to R, change it to grayscale, make some

REad bitmap files
Dear all,
I am looking for a function that can read a simple bmp file and return me a matrix with their corresponding values.
I have already looked in the packages
require(ReadImages)
require(pixmap)
and also did apropos("image")
but I could not find something that can do something like that.
I have also tried the read.ftable but it also failed.

reading jpeg images?
Can someone advise me what the most sensible way is to read jpeg images?
For our work with image analysis and eye-tracking we have been using the
rimage package, on both Macs and Windows PCs. But while setting up a new
Windows machine yesterday, I see that rimage is regarded as orphaned, and no
Windows binary is available. I eventually found an old zip file for the
package, so I

.Rprofile replacement function setwd() causing errors
In my .Rprofile I have the following functions which display the
current directory in the main R window title bar,
and modify base::setwd() to keep this up to date. I like this because I
can always tell where I am in the file system.
cd <- function(dir) {
base::setwd(dir)
utils::setWindowTitle( short.path(base::getwd()) )
}

Problem/anomalous behavior with image() function (and ReadImages?)
When an RGB photo is displayed using R's image() function with
the help of the pixmap (or rimage) package it is common to see
an anomalous white line running across the picture (either
horizontally or vertically). The line can
be removed by simply stretching the image frame a little in the
direction perpendicular to the anomalous line, or by maximizing the
image frame (tested under Fedora 10;

R help question: How can we enable useRs to contribute corrections to help files faster ?
Hello dear R users,
*Here is the background for my question:*
I just had a look at the help file for

In it, I found a small spelling mistake where the word "*c*istribution" was
written instead (so I imagin) "*d*istribution".
I thought maybe I should e-mail the developer. Since there is no link to

Rose diagrams in R?
I am looking for a function (or package) to plot histograms of directional
data such as wind direction. I believe these are called rose diagrams. Is
there an R script for this? If not, can it be constructed in a function
calling primitive graphic calls (lines, circles, boxes or polygons)?
The stars function is not quite right.

silently testing for data from another package for .Rd examples
In an .Rd example for a package, I want to use data from another
package, but avoid loading the entire
package and avoid errors/warnings if that other package is not available.
If I don't care about loading the other package, I can just do:
if (require("ElemStatLearn", quietly=TRUE)) {
data(prostate)
# rest of example
}
I'd rather just be able to do something like:

Bloomberg data import
Dear R Folks,
I know that Enrique Bengoechea ( Credit Suisse ) had posted some code
snippets for importing Bloomberg historical data into R.
I found them to be very useful.
Has anyone succeeded in getting the below items
from Bloomberg to R?
(a) historical economic release data,
(b) tick/intra-day data
(c) bulk data such as Index membership info, etc.
