Hi,
I would like to use the C spline functions if R for a FORTRAN subroutine. What
header file should I refer to?

I would like to generate a natural spline where the slope beyond the last knot
(the right outer knot) is constrained to be 0.
Is that available in some package around?

Hello all,
I have been working with b-splines and noted that the splines package is
not available in CRAN. Does any body know what happened with it?
Or, is there any package that replaces it?
Thank you

It should be included in your binary download of R. Is it not?

You likely need to load the package before you can use it:
library(splines)
? bs
works for me.

Hi,
I am looking at the change in N concentration in plant roots over 4 time
points and I have fit a spline to the data using ns and lme:
fit10 - lme( N~ns(day, 3), data = rcn10G)
I may want to adjust the model a little bit, but for now, let's assume it's
good. I get output for the fixed

kindest regards,
It should come with R since it is a base package.

Does anyone know if R has a function for splines under tension. I know
there are numerous packages for spline interpolation within R i just
can't find one that lets you determine the tension factor.

Dear R-Users!
I am trying to fit a spline to a time-series with about 90 values.
I would like to specify about four to five knots and I would like the
values returned to be similar in fashion to the output of interpSpline -
I would only like the
I want to fit a cubic spline of x on y. where :
x
[1] 467 468 460 460 450 432 419 420 423 423
y
[1] 1 2 3 4 5 6 7 8 9 10
using the syntax
spline(y, x)
I got following output :
$x
[1] 1.00 1.310345 1.620690 1.931034 2.241379 2.551724 2.862069
As reported in ?spline, you should use splinefun() instead.
ff-splinefun(x,y)
ff(x0)
where x0=5.25 is your case.
best,
