Changelog

added a warning about packages that are required when the extraction of syntax can’t be carried out due to these missing dependencies

fixed a “bug” in a testthat-condition that resulted in an error on several systems

added a couple of helper functions: convert_to_omv (converts data sets from other formats - CSV, R, SPSS, SAS, Stata) to .omv merge_cols_omv (merges two or more data sets by concatenating columns) merge_rows_omv (merges two or more data sets by concatenating rows) long2wide_omv (converts data sets from long to wide, e.g., for running mixed-model-analyses in jamovi) wide2long_omv (converts data sets from wide to long, e.g., for running mixed-model-analyses in jamovi) sort_omv (sorts the dataset according to one or more variable)
implemented unit tests and code coverage for read_omv, write_omv, convert_to_omv, merge_cols_omv, merge_rows_omv, long2wide_omv, wide2long_omv, sort_omv
implemented treating variables in read_omv and write_omv as ordered factor if measureType has the value Ordinal
default for sveAtt in read_omv (now TRUE; it makes more sense to store this attributes be default since write_omv will give you an exact copy of the original data set if they are stored and the helper functions above also respect and adjust them)

fixed an error when assembling the file name in write_omv, added assembling the file name with normalizePath to read_omv
fixed missing retDbg-parameter in one of the examples

use zip R-package instead of utils to prevent that no ZIP-executable-file is found on Windows (utils::zip only works in cases where a zip.exe is found on the path)
use the (session-specific) temporary directory for creating files to be zipped and those files extracted
improved handling of the different variable types, implemented logical / boolean variables / data columns
improved handling of column attributes
added parameter retDbg (default: FALSE) to write_omv so that output for debugging is only produced upon setting it

bug fix in read_omv (some libraries required for syntax extraction are not available on certain platforms (Solaris, Windows with MinGW)
added documentation (pkgdown) in docs/
set up examples and lintr

bug in write_omv fixed (@MAgojam, #2); jamovi could not read the manifest (meta) when the file was created with write_omv on Windows (LF + CR, but only CR expected / decoded)
updated the Created-by in the manifest string to use the jmvReadWrite version
improved the README (switched it to be generated from Rmd so that the vignette could be included

renamed jmvRead to read_omv, and jmvWrite into write_omv
extracts syntax from analyses contained in the .omv-file (set the parameter getSyn = TRUE; default is FALSE)
imports the output from the .omv-file (set the parameter getHTM = TRUE; default is FALSE)

first implementation, reads (jmvRead) and writes (jmvWrite) files using a file format similar to jamovi 1.2 (can be read with more recent versions)
