Some tests have started to report problems with the use of uniroot. A typical warning is:
Warning (test-helpers_knitr.R:89:15): knit_print methods exist for all relevant classes and produce consistent output
Error for class StartingDose: Error in uniroot(f = function(x) { :
f() values at end points not of opposite sign
The warnings are all reported in test-helpers_knitr.R. The affected classes are
StartingDose
DualEndpointBeta
DualEndpointEmax
DualEndpointRW
DualDesign
TDDesign
No test fails as a result of this error.
The only calls to uniroot within the crmPack source code are on line 394 of Simulations-methods.R (summary-GeneralSimulations) and line 4009 of Design-methods.R (simulate-DADesign).
The error for StartingDose is particularly surprising as the class is not involved in any simulation.
