df	data.frame from read.pgn()
file	string path to destination file
add.tags	string vector containing additional tags to be parsed.
append	boolean (default FALSE), should games be appended to current file?
source.movetext	boolean (default TRUE), if set and SourceMovetext appears in df then write SourceMovetext as Movetext; else use parsed Movetext According to Seven Tag Roster rule: http://www.saremba.de/chessgml/standards/pgn/pgn-complete.htm#c8.1.1 The STR tag pairs appear before any other tag pairs: "Event", "Site", "Date", "Round", "White", "Black" and "Result".

f <- system.file("extdata", "2016_Candidates.pgn", package = "bigchess")
df <- read.pgn(f)
write.pgn(df, file = "my_file.pgn")
df2 <- read.pgn("my_file.pgn")
all.equal(df,df2) # TRUE
unlink("my_file.pgn") # clean up
