    nRowsColumnHeader = 0L, ..., fCreateTimestamp = fSetTimestampTimezone, 
    timezone = character(), fReadCsv = read_csv, 
    col_types = NULL)

Arguments

fileName	fileName to read
startTime	POSIXct of minimum starting time to read
endTime	POSIXct of maximum ending time to read
n_max	maximum number of rows to read, by default all. will be ignored if endTime is specified
nRowsHeader	number of header rows above column names
nRowsColumnHeader	number of header rows below column names e.g. with unit information for each column
