Neither calculateSumB can handle all cohorts < successionTimeStep

[ianmseddy]

sumB will become NA, as the subset returns an empty table

1. I don't think this is a "bug", it's a choice to only calculate sumB for the older cohorts, which is why there are several instances in the module were the function is not used and instead we calculate sumB := sum(B) (because we want all the cohorts to be included).
   see e.g. line # 32 in age-cohorts.R and line # 1350 in LBMR.R summaryRegen function

[ianmseddy]

Fair, but that means we should test whether you have at least 1 cohort with age > successionTimestep, to avoid calling it and hitting the error. I think anyway.

[CeresBarros]

sure, wanna implement :P?

@ianmseddy is this still an issue?
