read.table

Thanks a lot that works fine!

Next problem, if I would have my own package, and the file "test.csv"
would be located in the data directory

How to use the function data to get

data(test)

resulting in:

test

   %y-%m-%d VALUE
1 1999-01-01   100
2 2000-12-31   999

I think you might be stuck in a particular mindset about this.

Does the .csv file have to be called test.csv?

If not then if it is called data.csv say, you can have in your data 
directory a file test.R with the code:

read.table("data.csv", header = TRUE, sep = ";", check.names = FALSE)

Alternatively you can have the data in the file test.R, plus the code to 
read it in as desired. Creating a data structure and reading it back in 
with dput and dget is one way to do this.

See page 11 of the Writing R Extensions manual for the possible formats of 
files in the data directory:

"The data subdirectory is for additional data files the package makes 
available for loading using data(). Currently, data files can have one of 
three types as indicated by their extension: plain R code (.R or .r), 
tables (.tab, .txt, or .csv), or save() images (.RData or .rda). (All 
ports of R use the same binary (XDR) format and can read compressed 
images. Use images saved with save(, compress = TRUE) to save space.) Note 
that R code should be self-sufficient and not make use of extra 
functionality provided by the package, so that the data file can also be 
used without having to load the package."

would be located in the data directory

How to use the function data to get

 > data(test)

Also put in the data subdirectory the file test.R
with the commands to read  test.csv

Kjetil

resulting in:

 > test

    %y-%m-%d VALUE
1 1999-01-01   100
2 2000-12-31   999


Again Thanks in advance Diethelm Wuertz

Look at the check.names= argument to read.table -- you want to set it
to FALSE.  But rememeber that you'l have to put quotes around the name
whenever you use it, as in x$'%y-%m-%d'

I have a file named "test.csv" with the following 3 lines:

%y-%m-%d;VALUE
1999-01-01;100
2000-12-31;999

read.table("test.csv", header = TRUE, sep = ";")

delivers:

  X.y..m..d VALUE
1 1999-01-01   100
2 2000-12-31   999


I would like to see the following ...

   %y-%m-%d VALUE
1 1999-01-01   100
2 2000-12-31   999


Note,

readLines("test.csv", 1)

delivers

[1] "%y-%m-%d;VALUE"


Is this possible ???


Thanks DW
