问题描述
假设我有以下数据框,命名为高表达
Suppose I have got the following data frame, named highly expressed
| |New IDs | Mean amast| Mean promast|Old IDs |
|:---|:---------------|----------:|------------:|:--------------|
|44 |LdBPK_010009200 | 37.16175| 33.72800|LdBPK_010440.1 |
|46 |LdBPK_010009300 | 35.67275| 32.05529|LdBPK_010440.1 |
|83 |LdBPK_010012800 | 6.84300| 16.04800|LdBPK_010790.1 |
|84 |LdBPK_010012900 | 6.92775| 15.62371|LdBPK_010790.1 |
|93 |LdBPK_020005100 | 5.89950| 27.03371|LdBPK_210020.1 |
|300 |LdBPK_030014900 | 7.59575| 12.38143|LdBPK_030960.1 |
我现在想获取一个列表,其中仅包含旧ID下的字符串(即整个第四个列)以进行进一步的数据处理。当我编写以下命令时:
I now want to get a list containing exclusively the strings under "Old IDs" (i.e. the whole fourth column) for further data manipulation. When I write the following command:
write.table(highly_expressed$`Old IDs`, file = "test", quote = F, sep = "\t")
我的输出文件包含两列(不仅只有一列,正如我所期望的那样),如下所示:
my output file contains two columns (an not only one, as I was expecting), as shown below:
| X|x |
|--:|:--------------|
| 1|LdBPK_010440.1 |
| 2|LdBPK_010440.1 |
| 3|LdBPK_010790.1 |
| 4|LdBPK_010790.1 |
| 5|LdBPK_210020.1 |
| 6|LdBPK_030960.1 |
有人知道不带列0写入文件的方法吗(索引1、2、3 ,4等)?也许使用了write.csv以外的其他功能?
Does anyone know a way to write to file without the column 0 (the indices 1, 2, 3, 4 etc)? Maybe using another function other than write.csv?
推荐答案
只需添加 row.names = FALSE
放入 write.table()
。
