Hey there!
I'm having problems with the same code, but I get a different error:
This is apparently yet another example demonstrating why the Posting Guide
suggests that you include the

Error in .C("spline_coef", method = as.integer(method), n = n, x =

I'm using R3.1.0 on windows 8 and I've never used R before, so I might
have
made some terrible newby error (I have programmed quite a bit before,
but in C
and Matlab).
Thank you!

Hi David,
Thank you for answering. The original message I replied to was this message
(http://comments.gmane.org/gmane.comp.lang.r.general/113245):

Hi all,
I have issues using some basic functions in R such as these ones :
pp.test(R) (where is a vector of returns)
Error in .C("R_approx", as.double(x), as.double(y), as.integer(nx), xout =
as.double(xout), :
C symbol name "R_approx" not in DLL for package "base"
boxcox(reg,plotit=T) (where reg is an lm object)
Error in .C("spline_coef", method = as.integer(method), n = as.integer(nx),
:
C symbol name "spline_coef" not in DLL for package "base"
as I do miss some symbol names.
How can I overcome this serious problem ?
***********************************
But someone else reported a very similar problem (oddly enough using the
same function spline_coef but this time from the package stats rather than
base (http://comments.gmane.org/gmane.comp.lang.r.general/115420):

Subject: Missing "spline_coef" DLL and Rob Hyndmans monotonic interpolator
Hello R help
I have been trying to use Rob Hyndman's monotonically increasing spline
function. But like another user or two seem have a problem with a
missing DLL (namely "spline_coef"). None of the previous help postings
seemed to have any solutions to this problem. As per a Ripley
suggestion I have deleted all previous versions of R and reinstalled R
2.7.0 and the problem persists.
Thanks
Paul.
x <- seq(0,4,l=20)
y <- sort(rnorm(20))
plot(x,y)
lines(spline(x, y, n = 201), col = 2) # Not necessarily monotonic
lines(cm.spline(x, y, n = 201), col = 3)
Error in .C("spline_coef", method = as.integer(method), n = nx, x = x,
:
C symbol name "spline_coef" not in DLL for package "stats"
Cm.spline code from
http://www-personal.buseco.monash.edu.au/~hyndman/Rlibrary/interpcode.R
**********************************
I hope that helps, thank you :)! I've tried calling spline_coef from both
stats and base, but I get the same error for both packages. I've also tried
the solution suggested to these people, which was to remove any other R
versions on my laptop.
Best,
