[R] stukel function unavailable for some odd reason

[Paul Bernal]

Dear friends,

I have been fitting a logistic regression and wanted to try a couple of
goodness of fit tests on the model.

Doing some research, I came across Chris Dardi's stukel and logiGOF
functions from package LogisticDx v0.1.

I tried installing package LogisticDx in different R versions without any
success.

I first tried installing LogisticDx package in R version 3.5.3 (for windows
64-bit OS) and this is what happened:

> install.packages("LogisticDx")
Installing package into 'C:/Users/PaulBernal/Documents/R/win-library/3.5'
(as 'lib' is unspecified)
--- Please select a CRAN mirror for use in this session ---
also installing the dependencies 'polspline', 'rms', 'speedglm', 'aod'

After this, I installed R version 3.6.0 and tried again:

The downloaded binary packages are in

> stukel(GLM.1)
Error in stukel(GLM.1) : could not find function "stukel"

Anyone can give me some light on what could be happening here? Do I have to
try with another R version? Is it something else?

Thanks in advance,

Paul
