trigammaInverse {limma} | R Documentation |
The inverse of the trigamma function.
trigammaInverse(x)
x |
numeric vector or array |
The function uses Newton's method with a clever starting value to ensure monotonic convergence.
Numeric vector or array y
satisfying trigamma(y)==x
.
This function does not accept a data.frame as argument although the internal function trigamma
does.
