Re: [R] Matlab import

2007-04-10 Thread tshort


I've used Henrik Bengtsson's R.matlab package several times to successfully
read in matlab data files. It's normally as easy as:

library(R.matlab)
mats - readMat(matrixM.txt)

 Dear R-Experts,
 
 here again a question concerning matlab. With the command matrixM=[1 2
 3;4 5 6] a matrix under Matlab was constructed. It was than stored with
 the command save('matrixM.txt','matrixM').
 
 Now I tried to import the data in R with the help of the command
 Z=matrix(scan(Z:/Software/R-Programme/matrixM.txt))
 
 An error occurred. 
 
 The result should be a matrix with the entries as mentioned above.
 Perhaps I made already an error in matlab. 
 
 Has any one got an idea how to import the data and store it in R. In R I
 want to make further calculations with the matrix. I just installed
 R.matlab but could not find an example with could help me.
 
 Thanks, Corinna

With readMat, don't use the -ascii option (which you didn't have in your
first posting). I've never tried reading matlab's ascii format. In any case,
readMat reads matlab's binary format.

 I have imported this package, too. And tried your commands with the new
 txt-file as mentioned in my last mail to the mailing list. 
 
 I get the following error command:
 mats = readMat(Z:/Software/R-Programme/test.dat)
 Error in if (version == 256) { : Argument hat Länge 0
 Zusätzlich: Warning message:
 Unknown endian: . Will assume Bigendian. in: readMat5Header(this,
 firstFourBytes = firstFourBytes) 
 
 What did I wrong? Please check my txt-file which was constructed with the
 matlab command save('test.dat','matrixM','-ascii')
 
 Thanks, Corinna

Re: [R] Rpad

2006-11-10 Thread tshort


Vittorio,

Those files being missing is what's causing the errors. Try recopying them
to your server home location.

Those files should be under Rpad/basehtml/gui/* in your R library
installation. If not, try reinstalling or extract the necessary files right
out of the Rpad_1.1.1.tar.gz file.

 I've just compiled and installed Rpad from the sources under *nix

 setup an  Rpad server  step by step.
 Now when I try to execute whatever 
 .Rpad example file the IE browser hangs endlessly with a loading page 
 pop-up and the following errors show up at the end of the html page:
 ..

 Now the 
 various .js files cited in the debug list of errors (by the way Errore 
 di sintassi means Syntax error, i.e. exactly the same thing!!!) are 
 actually missing in the ../basehtml/src/ directory. 
 
 Besides, what 
 should I do as far as  dojo.xml.domUtil is deprecated is concerned?
 
 Ciao
 Vittorio

Re: [R] HTML nsmall vector format problem

2006-06-09 Thread tshort


John,

I don't think nsmall uses a vector. Try the following with format (which
HTML.data.frame uses):

 format(iris[1:2,1:2],nsmall=c(3,1))
  Sepal.Length Sepal.Width
15.100   3.500
24.900   3.000

It looks like you'll have to do a format column by column with a loop.

 Hello All
  
 I am having a bit of trouble formatting my HTML with the desired number
 of digits after the decimal place. Am I doing something
 wrong/misunderstanding or is it a bug?
  
 Looking at the example supplied with ?HTML.data.frame:
  
  HTML(iris[1:2,1:2],nsmall=c(3,1),file=)
 
 Gives html output that includes the lines:
  
  /tr trtd class=firstcolumn1/tdtd
 class=cellinside5.100/tdtd class=cellinside3.500/td/tr
  trtd class=firstcolumn2/tdtd class=cellinside4.900/tdtd
 class=cellinside3.000/td/tr
 
 My understanding of how nsmall works, as a vector, the output should be
 something like:
  
 /tr trtd class=firstcolumn1/tdtd class=cellinside5.100/tdtd
 class=cellinside3.5/td/tr
  trtd class=firstcolumn2/tdtd class=cellinside4.900/tdtd
 class=cellinside3.0/td/tr
 
 i.e. first column with 3 digits after the decimal place and the second
 column with 1 digit after the decimal place.
  
 It appears to only use the first value in the vector.
  
 Has anybody got any suggestions?
  
 Thanks for any help.
