我从 ff 或 ffbase 包中运行 read.csv.ffdf。但它被以下消息卡住了
read.table.ffdf 1..1000 (1000) csv-read=0.15sec ffdf-write=1.24sec
read.table.ffdf 1001..63015 (62015) csv-read=9.89sec ffdf-write=8.84sec
read.table.ffdf 63016..125030 (62015) csv-read=8.18sec ffdf-write=6.74sec
read.table.ffdf 125031..187045 (62015) csv-read=8.15sec ffdf-write=6.72sec
read.table.ffdf 187046..249060 (62015) csv-read=8.19sec ffdf-write=6.72sec
read.table.ffdf 249061..311075 (62015) csv-read=8.05sec ffdf-write=7.13sec
read.table.ffdf 311076..373090 (62015) csv-read=8.26sec ffdf-write=6.73sec
read.table.ffdf 373091..435105 (62015) csv-read=8.26sec ffdf-write=6.8sec
这些文件包含大约 800000 行,但为什么它会停在这里,从那时起我不能运行任何东西?
