Vpc plots doesn't start from time zero. #39

Closed Sibojang9 closed 7 years ago

Sibojang9 commented 7 years ago

The lines and shaded area always start from some points after the time zero, leaving the very front part blank. Not sure that this is due to the vpc nature or something else. The following vpc zooms in the first 5 hours of the theophylline case in the online tutorial. clipboard_20170520 Thank you,

Yes, this is supposed to look like that: the lines / areas connect the weighted midpoints of the bins over the x-axis. If you prefer to have the "blocky" version of the vpc where all bins are shown more explicitly you should specify the "smooth=TRUE" option.

Where should I put that "smooth=TRUE" option? I tried to put it under either show=list() or vpc_theme=() but no success. Thanks.

it's an argument to the main vpc() function. I realize now this specific argument is not included yet in the documentation at vpc.ronkeizer.com. It is however explained in the help files, type ?vpc to get more info on all arguments.

I set the "smooth=FLASE' and now it would start from time zero. However, the noncontinuous bins apparently look not as pretty as the smooth one. I guess manual specification of smaller bin would make it smoother. Thanks. clipboard_20170521
