units of summary on models #21

Closed xhdong-umd closed 6 years ago

xhdong-umd commented 6 years ago

My model summary table rely on the summary on model with units = FALSE, so I can convert the values by proper units.

I noticed the current version of ctmm is reporting with much smaller units, and I was assuming SI units, so my result is off a lot.

> summary(model_try_res[[1]][[1]])
$DOF
    mean     area 
16.34829 31.36117 

$CI
                                low         ML       high
area (square kilometers) 258.930587 380.155725 524.290131
tau position (days)        2.811414   4.740313   7.992622

The unintended consequences of new features...

chfleming commented 6 years ago

Sorry to take so long. I was in the middle of another bit of coding. This should be fixed now. I added an SI=FALSE argument to the ctmm:::unit() function instead of using threshhold=Inf, which only worked when meters and seconds were the smallest supported units.
