R Documentation

Function supports g.analyse. Not intended for direct use by user.

Description

Generates day specific analyses and fills corresponding output matrix, g.analyse.

                midnightsi, metashort, averageday,
                doiglevels, nfulldays,lastmidnight, ws3, ws2, qcheck,
                fname, idloc, sensor.location, wdayname, tooshort, includedaycrit,
                doquan, quantiletype, doilevels, domvpa,
                mvpanames, wdaycode, ID,
                deviceSerialNumber, ExtFunColsi, myfun, desiredtz = "",
                params_247 = c(), params_phyact = c(),
                ...)

Arguments

`ndays`	Number of days in file

`ExtFunColsi`	column index of metashort where metric is stored
`myfun`	External function object to be applied to raw data, see g.getmeta.
`desiredtz`	see g.part1
`params_247`	See g.part2
`params_phyact`	See g.part2
