combineFiles: Combine Textfiles into one

Description

Combine several textfiles into one, regardless of their content.

Usage

combineFiles(inFiles = dir(), inDir = getwd(), outFile = "combined_Textfiles.txt", outDir = inDir, sep = NULL, names = TRUE, selection = NULL, progbar = !quiet, quiet = FALSE)

Arguments

inFiles

vector with names of input files, as can be read with scan. Is pasted with inDir, so don't use full paths. DEFAULT: dir()

inDir

Character string: path to the files. E.g. "D:/MyFolder/Subfolder". Don't have / at the end. DEFAULT: getwd().

outFile

Character string: name of the file to be created. Again, just the file name, not a path. DEFAULT: "combined_Textfiles.txt"

outDir

Character string: path for output file. DEFAULT: inDir

sep

Character string: Separation between content of each file and the following. DEFAULT: NULL, with which it uses an empty line, two lines with dashes, and another line break.

names

Should File names be included after sep? DEFAULT: TRUE

selection

Index of rows that should be written. Can refer to each file separately, e.g. substr(inFile_i,1,1)=="#", DEFAULT: all lines

progbar

Should a progress bar be drawn? Useful if you combine many large files. DEFAULT: !quiet, i.e. TRUE

quiet

Suppress message about number of files combined? DEFAULT: FALSE

Value

None, but prints number of files combined and output file name.
