In kitbenjamin/analysisToolsLUMA: Tools that can help speed up data analysis for LUMA instruments

Description

Plot a scatter graph and time series, along with a few statistics, of a variable for two instruments or processing levels.

Usage

plotLUMARegression(
  instrument1,
  instrument2,
  startDate,
  endDate,
  variable,
  fileTimeRes,
  DRIVE = NULL,
  tickBreaks = NA,
  dateLabelFormat = NA
)

Arguments

instrument1, instrument2	the first instruments to compare. These must be lists containing at least id, site and level. id must be consistent with the LUMA metadata site. ECpack is an optional name in the list. If level is RAW than rawFileParams must be included. rawFileParams is a list containing the elements: sep, variableColNos, timeColFormat and optionally skipRows. use ?getLUMAdata for more information on these.
startDate, endDate	the time span to get data for. Must be class date or POSIXct.
variable	the variable to compare between instruments. Must be consistent with LUMA metadata site.
fileTimeRes	The file time resolution- this must be the same for each instrument.
DRIVE	If running on windows which drive is /storage/basic/micromet mapped to e.g. Z
tickBreaks	How often ticks should appear on time series plots. e.g. 6 hours. See https://www.rdocumentation.org/packages/ggplot2/versions/1.0.0/topics/scale_x_datetime date_breaks for valid options.
dateLabelFormat	The format of date labels on time series plot e.g. with Hour and Minute separated by : . See date_labels in link above for valid options.

Examples

#for processed data
instrument1 <- list(id = 'DAVIS', site = 'IMU', level = 1)
#for raw data
inst2rawFileParams <- list(sep = ',', variableColNos = 2, timeColFormat = '%Y-%m-%d %H:%M:%S')
instrument2 <- list(id = 'SWTWXSTATION', site = 'SWT', level = 'RAW',
                    rawFileParams = inst2rawFileParams)
startDate <- as.Date('2020-01-20')
endDate <- as.Date('2020-01-28')
variable <- 'Tair'
fileTimeRes <- '1min'
tickBreaks <- '1day'
dateLabelFormat <- '%j'
regData <- plotLUMARegressionData(instrument1, instrument2, startDate, endDate,
                                 variable, fileTimeRes, tickBreaks, dateLabelFormat)
