In jkennel/transducer: Reads RBR files

Reading and exporting a folder of RBR files

This is the general format to read a file in and export them to csv.

# file that comes with the package
f_name <- system.file("extdata", "example.rsk", package="transducer")

dat <- read_rbr(f_name)                    # read data
write_rbr(dat, tempdir())                  # write data to temporary folder
write_rbr_info(dat, tempfile())            # write meta data to temporary file

Reading and exporting downsampled RBR files

We can export 24 *.rsk files (each ~ 400 MB) containing one second data to hourly data. Pressure and temperature will be output to separate files.

# location of *.rsk files
f_name <- list.files('/media/kennel/Data/phd/personnel/pat/syngenta/', 
                 pattern = '*.rsk',
                 full.names = TRUE)
print(f_name)

dat <- read_rbr(f_name,
           start = "2014-12-08", 
           end   = "2015-04-13",
           by    = 3600)                          # read data (hourly)
write_rbr(dat, tempdir())                         # write data to temporary folder
write_rbr_info(dat, tempfile())                   # write meta data to temporary file
