funcall

Applies an expression to vector v, optionally inverting the expression
first. For example if the expression is log, funcall returns log(v) if
inverse is FALSE, and exp(v) if inverse is TRUE.

Functions for fitting and plotting SITAR (Super
Imposition by Translation And Rotation) growth curve models. SITAR is
a shape-invariant model with a regression B-spline mean curve and
subject-specific random effects on both the measurement and age
scales. The model was first described by Lindstrom (1995)
<doi:10.1002/sim.4780141807> and developed as the SITAR method by Cole
et al (2010) <doi:10.1093/ije/dyq115>.
