c:/workspace/test.txt中有一个数据文件（不是固定宽度格式的数据文件）。
24.9444 24.7500 24.5555 24.3389 24.0389 23.7667 NA
24.7500 25.0167 25.6800 26.3055 24 26.1833 25
25.5778 25.6000 25.5167 25.3944 25.1889 24.9389 24.6778 24.3833 24.0944 23.8
25.5778 25.6000 25.5167
我读了它，得到了结果。

我可以将数据文件解析为下吗？

答案 0 :(得分：0)
这取代了NA，其中找到了7个空白的序列，然后正常读取它：
