[R] automated image processing

2009-12-08 Thread Martial Sankar

Hi,

I am looking for a R package which is capable to process and analysis pictures 
of tissues (stained) in an automatic way.

I had a look on biops and EBImage (Bioconductor) but they are not automatic...

Did you already use/know a such package ?

Thanks,

- Martial

[R] outlier detection test for large data set

2009-08-11 Thread Martial Sankar

Hello,

Which outlier detection test is robust for large dataset ?

I think the detection test in the package 'outliers' are suitable for small 
data set (between 3 and 100).
Do you know one for 2 or more values ?

Thanks,

- Martial

[R] R function found in two packages !

2009-06-18 Thread Martial Sankar

Hi,

Is there a mean to automatically choose one version of the 'rbind' function ? 
By default, R chose the 'rbind' from {base}, i would lke to use the one from 
{IRanges}...
Is it possible to set that using 'par' ?

 ?rbind
Help on topic 'rbind' was found in the following packages:

  Package   Library
  IRanges   /us3/gcg18/martial/local/R_lib
  base  /usr/local/lib64/R/library

Choose one 

1: External Data Frame {IRanges}
2: Combine R Objects by Rows or Columns {base}

Thanks,

- Martial

 I am usually solving these issues with:
 base::rbind() or IRanges::rbind().

[R] Unable to use jpeg(), png() etc.....

2009-06-17 Thread Martial Sankar

Hello, 

I 've just re-installed R 2.9.0 on ubuntu 9.04.

I do not understand why I am unable to use simple device function such as 
jpeg(), png()...

 png()
Error in X11(paste(png::, filename, sep = ), width, height, pointsize,  : 
  unable to start device PNG
In addition: Warning message:
In png() : no png support in this version of R


 capabilities()
jpeg  png tifftcltk  X11 aqua http/ftp  sockets 
   FALSEFALSEFALSEFALSE TRUEFALSE TRUE TRUE 
  libxml fifo   clediticonv  NLS  profmemcairo 
TRUE TRUEFALSE TRUE TRUEFALSEFALSE 

It's not really a problem because i use cairo but i would like to know the 
source of this error.

I checked the library as proposed in previous post : 

https://stat.ethz.ch/pipermail/r-help/2005-December/085177.html

but all of them (libpng, libjpeg...) are already installed.

Did someone ever find the source of this R Error ?

Thanks !

Re: [R] shall I uninstall an old R installation in advance of installing a new one ?

2009-06-17 Thread Martial Sankar

Hello Maura,

 Date: Wed, 17 Jun 2009 14:07:44 +0200
 From: mau...@alice.it
 To: r-h...@stat.math.ethz.ch
 Subject: [R] shall I uninstall an old R installation in advance of
 installing a new one ?
 
 I have resumed developing R code on SuSE/Linux version 11.1
 I installed the latest 64-bit R version available for my platform. 
 Accidentally I figured out I still had an old R installation that, 
 surprisingly, was not wiped out 
 by the new SuSE installation from scratch.
 I suspect the new and old R versions got mixed up. 
 I would greatly appreciate some suggestions about restarting from scratch a 
 new R installation.
 
 My question is: how can I remove the old R installation so that no old files 
 are left in the system ?

I am not familar with Suse, maybe you should remove R with a Suse equivalent of 
the command line 
apt-get remove 'name of the R package in Suse'

After that if some files or directory are not removed manually removed them 
with rm.

 
 Moreover, if I choose to install the new R version without previous disk 
 saving  ... where does R get installed (path) ?

For default path installation, please refer to the R-admin manual.
http://cran.r-project.org/doc/manuals/R-admin.html
 

Cheers,

- Martial


 Thank you.
 Maura

[R] web interface for R script??

2009-05-15 Thread Martial Sankar

Dear All,

I requiered your feedbacks about a web interface for R scripts.
I already tested RGG ( but it's not web).

and two of the CRAN list : Rserve  Rpad.

However, Rpad requieres some knowledge in Javascript, php etc...
and with Rserve I have to create a web interface entirely.

Rwui from the cran list seems attractive.

Did you ever test this one ?
Other suggestions are welcomed too ^^

Thanks,

- Martial

[R] access to the current element of lapply

2009-05-13 Thread Martial Sankar

Dear All, 

I would like to use the 'split' function on the dataframe elements contained in 
a list L.

For example : 

 (df - data.frame(cbind(c(rep('A',2), rep('B',2)), rep(1:4
  X1 X2
1  A  1
2  A  2
3  B  3
4  B  4
 (L-split(df, df$X1))
$A
  X1 X2
1  A  1
2  A  2

$B
  X1 X2
3  B  3
4  B  4

Now, I would like to split EACH data frame, ie, according to column 2(X2).

 lapply(L, split, df$X2)

$A
$A$`1`
  X1 X2
1  A  1

$A$`2`
  X1 X2
2  A  2

$A$`3`
[1] X1 X2
0 rows (or 0-length row.names)

$A$`4`
[1] X1 X2
0 rows (or 0-length row.names)


$B
$B$`1`
  X1 X2
3  B  3

$B$`2`
  X1 X2
4  B  4

$B$`3`
[1] X1 X2
0 rows (or 0-length row.names)

$B$`4`
[1] X1 X2
0 rows (or 0-length row.names)


Warning messages:
1: In split.default(seq_len(nrow(x)), f, drop = drop, ...) :
  data length is not a multiple of split variable
2: In split.default(seq_len(nrow(x)), f, drop = drop, ...) :
  data length is not a multiple of split variable



I works but it's dirty.
How  could I do it properly, without warnings and 0 rows data frame in output ?
I thought accessing to the current element of 'lapply' to recuperate the vector 
of the column 2 would work.
i.e:

lapply(L,split, L[[current]][,2]) 


Is there a way to do something like that in R ?


Thanks in advance !

- Martial

[R] 'Dynamic' 3D plot

2009-05-08 Thread Martial Sankar

Hi,

I am looking for a R package to draw 3d plot. But not in a static way like 
scatterplot3d or stuff like that. I would like to make rotate the plot, to 
zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the 
biologist and bioinformatician, a R package which permitts to reproduce what 
pdb viewer does).

Does a Way exist to do something like that in R ?

Thanks,

[R] rjava - JDK not found

2009-04-30 Thread Martial Sankar

Hi,

I would like to test the new package RGG (R Gui Generator). This package 
requires the installation of several other package. 
One of them is rJava.
I installed sun-java6-jdk and run the R CMD javareconf but the installation 
still fails ! 

Do you have any ideas ?

I completely removed the java-sun version and install the openjdk instead.
I re-launched the R CMD reconf.

In fact the javareconf is called in sudo mode during the installation of the

How can I fix the java support in sudo  mode ? 

Any ideas ??
