SPSS and R do they like each other?
Hi,
I wonder how well SPSS and R communicate, because I
need SPSS but would like to do some data manipulations
in R. However I am very afraid of never ending
import-export-complications ? especially with all
those labels and extra information my SPSS files
contain. My data come from SPSS and have to be
exported to SPSS again (because I need to produce
special output tables, which would be hard to

I want to insert a recorde into a SQLite table by dbGetQuery(), but
there is a problem when the value contains quotation mark.

pulling out 1 country and 1 wave
Hello.
I am trying to pull out one country from a time series of 5 waves. For example I need Norway from the 5th wave. This is new to me. Typically, I work with country specific surveys.
data = norway
I have attached a .tiff of the codebook showing the variable names for Norway and the wave. They appear to be Norway = v218 and wave = v15. But perhaps I am wrong and this is part of the

RSQLite
Version 0.4-1 of the RSQLite package has been uploaded to CRAN.
RSQLite embeds the SQLite engine in R (see http://www.sqlite.org)
Changes include:
* Fixed problems exporting/importing NA's
* An new experimental dbWriteTable() method to create SQLite tables
from simple files (delimited unquoted fields), e.g.,
> dbWriteTable(con, "table_name", "file_name", ...)

R_LIBS difficulty ?
Hi, R people.
I'm shy reporting this, as a bug in this area sounds very unlikely. Did
I make my tests wrongly? I'm still flaky at all this. Let me dare
nevertheless, who knows, just in case... Please don't kill me! :-)
Not so long ago, I wrote to this list:

Excel (off-topic, sort of)
Except for the ability to perform circular recalculation, I believe that the closest programming analogy to a spreadsheet is a functional programming language. Check out Haskell (or LISP or Erlang) to do what you describe.

R-generated animation of a polynomiograph
Hi, people.
Two days ago, I sent to this list a little toy for exploring
polynomiographs (yet, the mathematical formulas were not polynomials
anymore, so the name is not really appropriate).
After studying R calls, expressions and functions a bit more, I gave
myself the homework of producing an animation out of my recent toy. The
resulting animation, and also the sources, are available at:

Truncated labels in hist (PR#8864)
Hi, people. Executing the following command:
hist(rpois(100,5), labels=TRUE)
yields a graphic in which some labels are truncated (on an X11 device).
The truncated labels are those over the highest bars. The hist function
should ideally manage enough room for the labels, automatically.
(Specifying ylim solves my problem, but yet, hist could be frienlier.)

RSQLite problems
Hi, I'm experimenting with using (R)SQLite to do data management. Here are
two little problems that I've encountered:
1. The presence of ',' in string values causes trouble since ',' is also the
delimiter used in the SQL statement.
2. A newline '\n' line attached to the last string value of each row.
Some examples:

Matrices given to pt? [was: [R] for loops and counters]
Hi, people.
I was a bit intrigued by the message quoted below. Indeed, if pt() is
given a matrix, it returns a matrix. Should this feature be documented?
?pt speaks about "a vector of quantiles", and says nothing about the
type of what it returns.
The same might presumably apply to other distribution-related functions.

xy.coords(MATRIX) bug in code or documentation (PR#8937)
Hi, people.
xy.coords() does not behave like its documentation says, when given some
matrices. ?xy.coords says:
If 'y' is 'NULL' and 'x' is a [...] formula [...] list [...]
time series [...] matrix with two columns [...]
In any other case, the 'x' argument is coerced to a vector and
returned as *y* component [...]

Suggestion for system.time()
Hi, people. A tiny suggestion for the system.time function.
Could the returned vector have names? These could be like:
c("User", "System", "Elapsed", "Sub.User", "Sub.System")
That would then produce self-documenting output.

R 2.5.1 - Rscript through tee
Hi, people.
I met a little problem for which someone might have a solution. Let's
say I have an executable file (named "pp.R") with this contents:
#!/usr/bin/Rscript
options(echo=TRUE)
a <- 1
Sys.sleep(3)
a <- 2
If I execute "./pp.R" at the shell prompt, the output shows the timely
progress of the script as expected. If I use "./pp.R | tee

Hi, people. Wandering in R archives, and seeing the message attached
below, I noticed that:

still segfaults on R 2.2.0, and thought I should be a good citizen and
report it, even if I do not have an actual problem
