R Utilities: Loading/Reading Data Files using miceadds

The function load.data is a wrapper function for loading or reading data frames or matrices.

The function load.files loads multiple files in a data frame.

load.data( filename, type=NULL, path=getwd(), load_fun=NULL, spss.default=TRUE, ...)

load.files( files, type=NULL, path=getwd(), ...)

Arguments

filename	Name of the data file (matrix or data frame). This can also be a part of the file name and the most recent file is loaded. filename can also be a vector which strings and a file is loaded which contains all the specified strings.
type	The type of file in which the data frame or matrix should be loaded. This can be Rdata (for R binary format, using load.Rdata2), csv (using utils::read.csv2), csv2 (using utils::read.csv), table (using utils::read.table; the dataset must have the file extension dat or txt), xlsx (using readxl::read_excel; or using the extension xls), sav (using foreign::read.spss), RDS. If an alternative data loading function load_fun is chosen, type must be the file extension.
path	Directory from which the dataset should be loaded. It can also be set to NULL if the absolute path is already included in filename.
load_fun	User-specified loading function
spss.default	Optional logical which is only applied for type="sav" indicating whether the arguments to.data.frame=TRUE and use.value.labels=FALSE are used.
...	Further arguments to be passed to load.Rdata2, utils::read.csv2, utils::read.csv, utils::read.table, readxl::read_excel, foreign::read.spss, or load_fun.
files	Vector of file names
