OK this does work:
I can subtract eg the titles. But how can I say R that it should make a
link between title, keyword and frequency of the keywords in order to
have a 3 d plot?
Thanks a lot for helping me until here anyway!
Cheers

Can you post the exact error message? Also, could you post a sample
data file (for example, on tinyupload.com) so that
I have uploaded the csv file here:
http://s000.tinyupload.com/?file_id=79349565739733953435
It contains the citations, which I generated from the bibtex file.
The exact error message is:
[2] ERROR:
more columns than column names
A screenshot of the Rcmd is located here:
The screenshot shows your error.
Just have a look at the error message in the bottom part of the window.
Your csv file has more columns than column names.

I looked at the data and there is a column name called ISBN#. Try to
remove # and then import the data.

Hello,
Sorry to arrive late on this. Did you try the recently uploaded bibtex
package. It reads a bibtex file into an R list (of class citationList).
So for example : if your posted example lives in biblio.bib for example,
you can read it like this :
bib - read.bib( biblio.bib )

Dear all,
i am new in R. I am writing a review paper about batteries. However, i
am interested in analyzing all the papers by keywords, author,
references and year.
This could be done by refviz a software, which is only running on
windows machines and which is not free.
So my question to you

Hi,
from what I understand, you may be interested in text mining, so perhaps
you want to look at the tm package.
Then again, depending on what you are really trying to do, you may be
better served with perl, awk and similar tools than with R...

Thanks for all the comments,
and sorry about the unstructured question! I am trying to:
1: analyze keywords, names from Authors and year of publication from
citations (with abstracts) i downloaded fron various sites(these
downloads can be converted into .txt files as well)

Ok good question I havent explain!
Well,lets keep it simple for the begining. By analyzing the
keywords(which can also include the authors name) I mean,
1) investigate in which paper the keyword occur and how often
2) investigate if keywords occur together
X axis can show the paper title (or
It sounds pretty simple so far. Just put the citation info in a data
frame, and plot it. I would use ggplot2 for plotting, but it could be
done in base or lattice too.

Thanks, but how should I put the citation inside a data frame?
data.frame(first txt file, second txt file...)
plot (what should I insert here) type=p
And how should I load the txt files anyway inside the frame?

They are in Bibtex
For example:

I think I my original response was bad. And I also realize that I
don't really understand what you want to do.
Here is what I was thinking:

formats to .csv using Tellico or similar software). Then read the

I have tried
