国际象棋PGN：粘贴错误...结果将超过2 ^ 31-1个字节

Question

我正在使用R中的库bigchess来读取3GB PGN文件，请参见此处的源代码：https://github.com/rosawojciech/bigchess

像这样阅读它：

df <- read.pgn(paste0(path, file), add.tags = c("UTCDate", "UTCTime", "WhiteElo",  "BlackElo", "WhiteRatingDiff", "BlackRatingDiff", "WhiteTitle", "BlackTitle","TimeControl", "Termination"), n.moves = T, extract.moves = -1, stat.moves = T, big.mode = F, quiet = F, ignore.other.games = F)

我收到以下错误-

  

“粘贴错误（subset（r2，tmp1 ==“ Movetext”，select = c（tmp2））[，1]，   ：结果将超过2 ^ 31-1字节”

存在基于Internet的搜索，因为R无法在内存中存储大于2Gb的字符向量。有没有办法超越此限制，或者以其他方式解决问题？
