R-beta: spline problems(?)
Hi,
I am a total beginner with this whole thing so please have patience!
I am trying to run an S-plus program with a certain line:
spline(1:nrow(y), y[,1],n=100);
This crashes with:
Error: NAs in foreign function call (arg 8)
Apparently, this is caused by the last command of spline:
u <- seq(xmin, xmax, length.out = n)

Spatial join – optimizing code
Hi,
Few days ago I have asked about spatial join on the minimum distance between 2 sets of points with coordinates and attributes in 2 different data frames.
Simon Knapp sent code to do it when calculating distance on a sphere using lat, long coordinates and I've change his code to use Euclidian distances since my data had UTM coordinates.
Typically one data frame has around 30 000 points

Why are Split and Tapply so slow with named vectors, why is a for loop faster than mapply
First, here's the problem I'm working on so you understand the context. I
have a data frame of travel activity characteristics with 70,000+ records.
These activities are identified by unique chain numbers. (Activities are
part of trip chains.) There are 17,500 chains.
I use the chain numbers as factors to split various data fields into lists
of chain characteristics with each element of

I have 4 web servers with lighttpd to serve one web site with DNS load

in 'sbwait' state every day. It means the php-cgi stay in 'sbwait' state,
and never be back to 'accept' or other state. If I restart them, there will

performance gap between R 1.7.1 and 1.8.0
Dear R-help,
A colleague of mine was running some code on two of our boxes, and noticed a
rather large difference in running time. We've so far isolated the problem
to the difference between R 1.7.1 and 1.8.0, but not more than that. The
exact same code took 933.5 seconds in 1.7.1, and 3594.4 seconds in 1.8.1, on
the same box.
Basically, the code calls boot() to bootstrap fitting mixture

R interpreting numeric field as a boolean field
Dear friend Duncan,
Thank you so much for your kind reply. Yes, that is exactly what is
happening, there are a lot of NA values at the start, so R assumes that the
field is of type boolean. The challenge that I am facing is that I want to
read into R an Excel file that has many sheets (46 in this case) but I
wanted to combine all 46 sheets into a single dataframe (since the columns

The error message is always estimated breakpoints are out of range.

Yes. With that many files, file.choose() does not make sense. However, I
still do not understand what is the problem with using lapply() on the
character vector of file names with read.table() as you did in your
