Merge excel files in R-CodePudding

I imported 8 Excel files into r and the content of the files are the same.

Now I want to merge these 8 files into one. I used the function merge. Here is my code:

> merge1 = merge(Data1.1, Data1.2, all.x = TRUE, all.y = TRUE)
> merge2 = merge(merge1, Data2.1, all.x = TRUE, all.y = TRUE)
> merge3 = merge(merge2, Data2.2, all.x = TRUE, all.y = TRUE)
> merge4 = merge(merge3, Data3.1, all.x = TRUE, all.y = TRUE)

Somehow R didn´t took all the rows from Data3.1 . The rows from merge 3 are 1.913.573. The rows from Data3.1 are in total 479.273. The rows in merge 4 are just 1.919.232 instead of 1.913.573 479.273 = 2.392.846.

Why r didn´t took all of the rows from Data3.1?

Thank u guys!!!!

CodePudding user response：

If you have same column names and same number of columns in all 8 files (as it looks like since you said 'content of the files are same'), you should use rbind function.

Newdf <- rbind(Data1, Data2, Data3, Data4, Data5, Data6, Data7, Data8)

Note that R will throw an error in either of the following scenarios:

The data frames don’t have the same number of columns. The data frames don’t have the same column names.
