|
input |
a data.table or data.frame object to write out |
file |
file path to which the rscv will be written |
strings.convert |
global switching of storage conversion types |
strings.as.factor.ints |
logical, convert strings to factors, and write to file as integer. May save space on disk |
factors.as.ints |
logical, write factor columns to file as integer, with "levels" stored in a header object. May save space on disk |
dates.as.ints |
logical, write date columns to file as integer, with "tz" stored in a header object, and origin assumed to be "1970-01-01". May save space on disk |
posix.as.num |
logical, write POSIXct columns to file as numeric, with "tz" stored in a header object, and origin assumed to be "1970-01-01 00:00:00". May save space on disk |
times.as.num |
logical, write 'chron::times' columns to file as numeric. Allows for sub-second precision to be stored, as opposed to converting times to character, therefore only storing precision to seconds |
ITimes.as.ints |
logical, write 'ITime' columns to file as integers. May save space on disk |
logical.convert |
one of "int"/TRUE to store as integers, "short" to shorten to "T" or "F", or "long"/FALSE to leave unchanged. May save space on disk |
notes |
single line of text. Add notes to the dataset. Will be displayed in the console when data is impoted by 'read_rcsv', and stored in the imported data frame as an attribute "notes". By default, any existing "notes" attribute is stored here. |
write out an rcsv file, an extension of csv, with column format details stored in a header for more consistent reading into R
