Problems with paste and blank
Hi there,
I've got the following problem under Windows XP, R 2.5.1:
When I'm pasting some objects:
Stadtwerksname<-"Mannheim"
Laufwerk<-"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 to read non-standard csv file
Hi all,
I have a problem to read csv file with comma as decimal. The numbers were
readed as strings.
I used the following string in R, but I do not understand why it does not
work.
tab <- read.csv2("Specimen_RawData_1.csv", header = TRUE, sep = ";", dec =
",", nrows = -1)
In addition, I copy/past into the post the link to the csv file generated by
my instrument.

import .csv file into R
Dear r-helpers,
I read a .csv file into R
with the following command:
A<-read.csv2(file="Mappe3.csv")
It worked fine, except that I would like to get rid of the points between
the words and get spaces instead like I have got in the .csv file.
At the moment it looks like the following:

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

write.csv suggestion
Hello all,
I had some trouble recently with write.csv because I couldn't change one
of the default options. A quick view of the code showed that the
function was not defined in the most optimal way.
Currently,
write.csv <- function (..., col.names = NA, sep = ",", qmethod =
"double")
write.table(..., col.names = NA, sep = ",", qmethod = "double")

reading csv-data
Hi!
I have had this problem for a long time. I have tried to study the manuals and
search the mailing lists, but I can not solve this. I think there has to be one
simple solution to this, but I just can not find it.
I have saved the data in excel (csv-format). Then I read the data in R e.g.

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…

two small wishes (with code sugegstions) for R-core
Dear R developers,
It would be great if you could implement the two minor code changes suggested below, which would help processing large objects in R.

# Wish no. 1: let [.AsIs return the class AFTER subsetting, not the class of the original object
# Wish no. 2: adjust write.csv and write.csv2 for multiple calls in chunked writing

Questíon regarding the use of write.csv2, write.table ...

I use "write.csv" and "write.table" to write a data frame in a file like
following:

But in the created file "allRandomTestCase.csv" an additional column with
consecutive numbers is automatically added to the column of the data frame
"allRandomTestCase_XDroped".

I am new R user and I am sure that this question has been asked quite often
and I have also googled it and read about it! I understood that in order to
read excel sheet into R you need to open it and saved it as csv or text, is
this true? or you can use read.delim2 and read.csv2 to do this without the
