merge different files into 1 text file in R

I have two files with one being text, and the other being a data frame, now I just want to merge them into one as a text file. With linux, I can use:

cat file1 file2 > outputfile

I wonder if we can do the same thing with R?

Answer

We can use file.append:

file.append("fileMerged.txt", "file1.txt")
file.append("fileMerged.txt", "file2.txt")

Or if files are already imported into R, then write with append:

#import to R
f1 <- readLines("file1.txt")
f2 <- readLines("file2.txt")

# output with append
write(f1, "fileMerged.txt")
write(f2, "fileMerged.txt", append = TRUE)
