Hi all,

I'm having major issues with smoothing my functional data

I'm referring to Jim Ramsay's
examples in his books. The following error message keeps appearing,
despite all my data being numeric.... can anyone kindly offer any suggestions?

isi - vector of argument values - i.e. the independent variable of the curves
rlz - data array
TMSfdPar - functional data parameter.

> TMSfdPar = fdPar(TMSbasis, 4, 0.01)
> TMSfdsmooth = smooth.basis(isi, rlz, TMSfdPar)
Error in smooth.basis(isi, rlz, TMSfdPar) : 'argvals' is not numeric.

I don't understand why the error message keeps popping up. I've tried playing around with Jim Ramsay's datasets and I think my data is organised in a similar manner to his, so can't understand what's going on.... oh, the frustration!

Thanks in advance,

Ben
