Problems with paste and blank
...<-"C:\\"
paste(Laufwerk,Stadtwerksname,".csv")
I get the result:
[1] "C:\\ Mannheim .csv"
The problem's are the superfluous gaps/blanks between the three parts.
Is there a way to get rid off this problem?
Thx,
Thomas

Maybe anyone could give me a hint where to start reading?

eMail results out of R
Hi everyone,
I did my homework and read the posting guideline :-)
I want to eMail the results of a computing automatically. So I get the results (the parameters of a garch process) and I want to eMail them to another person. How can I do that?
Thx

Forcing "virtual" digits
Hi there,
I'm using XP with R 2.6.1
I've got the following question: Is there a way to force "virtual" digits?
I mean: In the external csv-file, I read in some numbers, e.g. "33" which is
written into a variable.
I want to add this variable into a plot with an additional digit: "33.0".
I know, that this is a kind of cheating, because the

Avoiding "." when importing from csv
Hi guys, another question today:
If I import an external csv-file with headers (with read.csv2), the blanks
are interpreted as points. So "Test 1" becomes "Test.1".
Is there a way to change this?
Thanks,
Thomas

Jpeg and margin table, second attempt
...-function, only a little part of the margin text is
displayed in the final jpeg? Any ideas to change it?
The idea of Jim (using x11) produced another bug for me: A new window
was created at first, then everything was plotted into the second-one.
Thx,
Thomas

Jpeg and pixel
Hi guys,
I've got tthe following question:
Why do my fonts look a bit grubby when I use the jpeg() function? I see
the pixels of the font. The quality is set to 100%.
If this is normal with jpeg(), which function would you propose me to
use instead?
Kind regards,
Thomas

looping over a string
Hi list,
I'm using R 2.8.1 under Windows vista. I have the following problem:
First of all I create a string-vector. Then I "convert" these strings
into variables and assign a vector of numeric values. So far
everything's fine.
Now I want to do nearly the same again: I create another string-vector
and I want to assign the variance. So I have to loop over the first

mixed csv and csv2
Dear all,
I have a huge problem after downloading and exporting data from Reuters3000
XTra:
I downloaded many many monthly, quarterly and yearly data. I do not know
why, but after saving, I have mixed-data sets, i.e. files which can be
imported as “read.csv” and others that are in the format of “read.csv2”.
Sure I could change them, but normally it should be possible to mix them…
