In bgctw/RespChamberProc: Processing Data from Respiration Chambers

read81x

Description

Read a Licor generated .x81 file into a data-frame

Usage

read81x(fName, nRowsFileInfo = 23, sep = "\t", 
    ..., colsTimeStamp = 3, formatTS = NULL, 
    tz = "UTC", na.strings = c("", "NA", 
        "NAN", "\"NAN\""), labelRowOffset = -16)

Arguments

fName	scalar string: file name
nRowsFileInfo	scalar integer: number of lines of initial file information
sep	column separator
...	further arguments to readDat
colsTimeStamp	integer vector: colums with time stamp column (will be set to POSIXct)
formatTS	format of the timestamp columns, see strptime
tz	specify a time zone when converting to POSIXct, default: UTC
na.strings	see link{read.table}
labelRowOffset	the row offset, usually before concentration measurements to generate column label

version of readDat with adjusted defaults.

This function is deprecated because its superseeded by the more versatile read81xVar.

  "genData/Flux2_140929_1700.81x", package = "RespChamberProc")
if (nzchar(fName)) {
	ds <- read81x(fName)
	#plot( CO2 ~ Date, ds )
	#plot( CO2 ~ Date, ds[ds$iChunk == 9,] )
