,可以使用pandas库中的to_csv函数来实现。 首先,导入pandas库: 代码语言:txt 复制 import pandas as pd 假设要导出的DataFrame为df,可以使用to_csv函数将其导出为csv文件: 代码语言:txt 复制 df.to_csv('output.csv', index=False) 其中,'output.csv'为导出的csv文件的文件名,index=False表示不在csv文件中添...
How to save an R data frame as txt file - If we want to use a data frame created in R in the future then it is better to save that data frame as txt file because it is obvious that data creation takes time. This can be done by using write.table function.
However, to get the most from them I would recommend that you create an project and within that open (and save) a new RMarkdown file each time to work through a tutorial. Within that Markdown file, replicate parts of the code from the tutorial (in code chunks) and use Markdown to ...
可以用load("exprSet_rmdup.Rdata")打开,或左上角File-Open File btw,把R保存为csv文件可用write.csv(exprSet,file="excel1.csv")
