sincfilter: A function for sinc-interpolation
In neuroconductor/fmri: Analysis of fMRI Experiments

Performs sinc interpolation for a equidistant time series x to times t.

1	sincfilter(t, x, wr=8)

`t`	vector of new time points
`x`	observed time series at times `1:length(x)`.
`wr`	determines truncation of series expansion

a vector of interpolated values of the time series at time points given in t.

  x <- 1:107
  y <- rnorm(x)
  z <- sincfilter(seq(1,107,.01),y)
  plot(x, y, ylim=range(y,z))
  lines(seq(1,107,.01),z,col=2)
