[R-pkg-devel] Warning from dependencies: 'fields::fastTpsMLE'

[Jin Li]

Many thanks, Michael.

The `fastTpsMLE` was used to estimate `lambda` for `Tps` as below:

library(fields); library(spm); data(petrel)
x=petrel[, c(1,2)]; y=petrel[, 5]; theta = 3

lambda <- fields::fastTpsMLE(x, y, theta = theta)$lambda.best
lambda
[1] 0.9875504

I have just updated the `fields` package. However, `lambda` is not reported
by `fastTps`. But I need an estimate of `lamda` for `Tps`. Is there a
solution for this?

Best,
Jin
