Changes to the trajr package

trajr 1.3.0

• Detect and report some invalid parameter values.
• Altered handling of parameter readcsvFn to TrajsBuild to make it possible to use readr::read_csv without a wrapper function.
• Added function TrajResampleTime to resample a trajectory to fixed step times.
• Added parameters start.pt.pch and start.pt.col to plotting functions.
• Added parameter dt to TrajTranslate
• Fix vertical extents of rectangles in plot.TrajSpeedIntervals to handle non-default ylim values.
• Added optional progressbar to TrajsMergeStats.
• TrajsMergeStats now passes the arguments stringsAsFactors = FALSE to rbind. This prevents incorrect behaviour and the warning “invalid factor level, NA generated” if one or more of your statistics are characters.
• Enhanced TrajRotate to allow absolute rotation and arbitrary origin of rotation.
