R：将数据写入csv文件中的特定列

Question

I have 2 functions, func1 and func2 whose job is to aggregate data from other input files, load them into data frames(df1, df2) separately and write to a single csv file. I am trying to get df1 and df2 to load different columns in the same csv file. Is this possible?

Sample Data:

Output.CSV:

Name  Age Sex Salary Deductions
Mike   50  M   50000  0
Molly  61  F   65000  500
Jake   22  M   28000  0

df1 loads Name Age and Sex columns. I want df2 to load the Salary and Deductions columns. In a nut shell, I basically am looking at an update(in RDBMS jargon) option where once df1 has loaded the first 3 columns, df2 should be able to update the other 2.

I'll appreciate any help or guidance. Thanks.

您可以在write.csv之前使用cbind df1和df2 ：

write.csv(cbind(df1,df2),"your csv path")
