In bigchess: Read, Write, Manipulate, Explore Chess PGN Files and R API to UCI Chess Engines

Description

Write PGN data.frames into file

Usage

write.pgn(df, file, add.tags = NULL, append = FALSE)

Arguments

df	data.frame from read.pgn()
file	string path to destination file
add.tags	string vector containing additional tags to be parsed. 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". Using this argument you can specify supplemental tag names, such as: Player related information, Event related information, Opening information (locale specific), Opening information (third party vendors), Time and date related information, Time control, Alternative starting positions, Game conclusion and Miscellaneous. Most popular: "WhiteElo", "BlackElo","ECO","SetUp" or "FEN". Case sensitive.
append	boolean (default FALSE), should games be appended to current file?

Examples

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
