I guess you are using package RSQLite without telling us (or telling us
the version), and that your example is incomplete?
Using RSiteSearch("RSQLite Windows") quickly shows that this is a
previously reported problem with the package, e.g.:
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/72515.html
I believe the issue is that RSQLite actually writes out a CRLF-terminated
text file and imports that into SQLite. (I checked version 0.4-15.) It
seems function safe.write() needs to be modified to write to a binary-mode
connection since SQLite appears to require LF-terminated files.
Using RODBC to work with SQLite databases works correctly even under
Windows (and is much more efficient at writing to the database).
[I am not sure who is actually maintaining RSQLite, so am Cc: both the
stated maintainer and the person who prepared the package for
distribution. The posting guide asked you to contact the maintainer: what
response did _you_ get?]

Hi,
I put the iris data into a SQLite database with
dbWriteTable(con, "iris", iris, row.names=F, overwrite = T)
Then I retrieve data from the database with
rs <- dbSendQuery(con, "select * from iris")
d1 <- fetch(rs)
dbClearResult(rs)
Then I get
head(d1)
Sepal_Length Sepal_Width Petal_Length Petal_Width Species
1 5.1 3.5 1.4 0.2 setosa\r
2 4.9 3.0 1.4 0.2 setosa\r
3 4.7 3.2 1.3 0.2 setosa\r
4 4.6 3.1 1.5 0.2 setosa\r
5 5.0 3.6 1.4 0.2 setosa\r
6 5.4 3.9 1.7 0.4 setosa\r
Can anyone explain the extra "\r" at the end? I am on Windows XP using R 2.4.1
Thanks in advance
Søren
