confusing errors with Q too large in binseg about changepoint HOT 4 CLOSED

I'm not sure what caused this but it looks like it is fixed in the latest version 2.2.3 just sent to CRAN.

Hi @rkillick thanks for the update! Now I see

> changepoint::cpt.mean(c(1,2,4), penalty="Manual", method="BinSeg", pen.value=0, Q=4)@param.est
Error in BINSEG(sumstat, pen = pen.value, cost_func = costfunc, minseglen = minseglen,  : 
  Q is larger than the maximum number of segments 2.5
> changepoint::cpt.mean(c(1,2,4), penalty="Manual", method="BinSeg", pen.value=0, Q=5)@param.est
Error in BINSEG(sumstat, pen = pen.value, cost_func = costfunc, minseglen = minseglen,  : 
  Q is larger than the maximum number of segments 2.5

This output is definitely better since the error messages are consistent.
However I am confused about the new error: what does it mean to have 2.5 segments?
Also my previous suggestion to change "segments" to "changepoints" would still be useful. As it is the error gives me impression that Q is the number of segments, but it is actually the number of changepoints, right?

I suggest the following error: "Q is larger than the maximum number of changepoints 2"

I've added the floor argument to the version headed to CRAN. Sorry I hadn't committed to github prior to sending the message.
