concatBlenderFiles: Concatenate Blender data files

In axzinker/blenderFace: Collection of functions to process blender measured facial movement data

Concatenate Blender data files

Description

Concatenate several csv or Rdata files into one large 'master'-file. Either csv or Rdata files can be concatenated, however, not mixed cvs/Rdata files. The data files must all reside in the same directory. The files need not to have the same number of colums, e.g., it is possible to concatenate files with a different number of markers tracked. The total number of columns will be determined during runtime of this function. Before concatenating the files, a feedback of the columns for the final data set is given and asked for it's correctness.

Usage

concatBlenderFiles(
  dataFileNames,
  inputDirectory,
  colNameSubj = "",
  verbose = FALSE
)

Arguments

dataFileNames	Character vector containing filenames to be concatenated. Possible file types are csv and R data files (file extensions: *.csv, *.rda, *.Rdata).
inputDirectory	Character vector of length one containing the path to the directory of data files (e.g., on Windows: 'C:/Data/Blenderdata/', on Unix-type systems: '/home/user/Data/Blenderdata/').
colNameSubj	Character vector of length one, default is empty (""). If empty, the subject number is taken from the last number in the file names of the single data files, which should be concatenated (in front of the file extension). For example, from the filename 'RawData_Subj_39.RData' the subject number 39 is taken. If the subject number is contained the single data files, the colNameSubj parameter must contain the column name of the subject column of the data files (e.g., colNameSubj = "subject").
verbose	Logical value. If TRUE, the function provides verbose console output.

Value

Returns data frame and saves Rdata file of concatenated input files.
