[R] Changing default library
Hallo R experts, I got a question concerning the .libPaths(). if I do the command .libPaths() than the result is /usr/lib/R/library. This is the default folder. I now want to change this one into /home/csc/usr/lib/R/library. I thought it would work with the command .libPaths(/home/csc/usr/lib/R/library). When I than do the command .libPaths() the result is: /usr/lib/R/library /home/csc/usr/lib/R/library. But if I start R the next time the result of the command .libPaths() is again just /usr/lib/R/library. Can anyone help me?

Re: [R] creating a new column
Hallo,
I just now a solution for da data frame. I'm not sure if this is what you want.
Just try if it helps. Here an example of my code where I added a column:
df - rbind( c(fred,mary,4),c(fred,mary,7),
c(fred,mary,9),c(barney,liz,3),
c(barney,liz,5))
df - data.frame(df)

Dec 12th, 1980,Apr 9th, 2003,
Apr 9th, 2003))
df
The R-Gui Result:
father mother child.ageweddingdate

3 fred mary 9 Dec 12th, 1980

5 barneyliz 5 Apr 9th, 2003
Caution: the number of entries in adding column must correspond to the number
of rows in your existing data frame df (here 5)

Dear R-Experts, in my program I have a big workspace. Now I want to look for all variables which have the letters 777 in their name (e.g. ask777first) and afterwards I need to delete those variables. How can I reach this aim? Any ideas, Corinna __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] information extraction
Dear R-experts,
I imported successful a workspace from Matlab. The information is stored
in the variable data. If I use the command length(data) I get back a
number which corresponds to the number of variables which were imported.
Here it is 82. Now I only want to know the names of the imported
variables to modify my program. Can anyone help me?
My knowledge which I tested yet to archive the goal:
1. I know that I can extract the information of a variable with the
command data$staine for example. Here I need to know the variable name
staine coming from Matlab. But what if I do not know it?
2. The command data[10] just gives me back the information stored in
the variable no. 10 but I do not know the name.
3. I am not allowed to make changes in the Matlab code because it just a
lizenced program so I need to do it in R. In Matlab I just need to add
the code line names=evalin('base','who') and than store the workspace.
I could use the variable name in and extract the names with data$names.
Has anyone an idea?
Thanks, Corinna

Hallo Peter,
thank you. It is exact what I wanted. Now I can modify my program.

Betreff: Re: [R] information extraction
Hi Corinna,
names() is what you are looking for, e.g.
names(data)
names(data)[10]
names(data) - a.vector.of.my.own.names
BTW, data() is a function in R, so it's better to avoid it as the name
of a dataframe.
for more information, see the documentation installed with R or one of
the contributed documents at
http://cran.r-project.org/other-docs.html
in particular the R and octave document will be relevant to you as a
matlab user.

Re: [R] Matlab import
Hallo,
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)
- Tom
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')

Re: [R] Matlab import
Hallo,
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.
- Tom
I did the saving again without 'ascii' option but the import also did not work.
I get the following error message:
library(R.matlab)
mats - readMat(Z:/Software/R-Programme/test2.dat)
Fehler in list(readMat(Z:/Software/R-Programme/test2.dat) = environment,

Hallo,
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)
- Tom
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:

What did I wrong? Please check my txt-file which was constructed with the
matlab command save('test.dat','matrixM','-ascii')

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

Re: [R] Reasons to Use R
Dear Mr. Isella, I just started my PhD Thesis. I need to work with R. Good sources are Bioconductor (www.bioconductor.org). It is a DB based on R-programming. Another institute which has good experiences with R is the HKI in Jena, Germany. Perhaps you can contact Mrs. Radke to get more information or speakers for your workshop. Both parties are mainly for bioinformatics methods but perhaps can help you. A good reason to use R is that computations are much quicker and you can import/export from many other programs or languages files.

I am planning to attend it and talk a bit about fluid dynamics, but there is also quite a lot of interest devoted to data post-processing and management of huge data sets. A lot of people are interested in image processing/pattern recognition and statistic applied to geography/ecology, but I would like not to post this on too many lists. The final aim of the workshop is understanding hardware requirements and drafting a list of the equipment we would like to buy. I think this could be the venue to talk about R as well. Therefore, even if it is not exactly a typical mailing list question, I would like to have suggestions about where to collect info about: (1)Institutions (not only academia) using R (2)Hardware requirements, possibly benchmarks (3)R clusters, R multiple CPU machines, R performance on different hardware. (4)finally, a list of the advantages for using R over commercial statistical packages. The money-saving in itself is not a reason good enough and some people are scared by the lack of professional support, though this mailing list is simply wonderful.
