R2MLwiN (version 0.8-6)

ws2foreign: Converts data from one format to another within MLwiN

Description

This function converts data from one format to another within MLwiN, via MLwiN macro language. The foreign package allows R to read data files for most of these formats.

Usage

ws2foreign(wsfile, foreignfile, MLwiNPath = NULL, x64 = NULL)

Arguments

wsfile

A file name specifying the data file (with a specific extension) to be converted.

foreignfile

A file name specifying the data file (with a specific extension) after conversion.

MLwiNPath

A path to the MLwiN folder. By default, MLwiNPath = NULL and path set by options('MLwiN_path'), the default for which can be changed via options(MLwiN_path = 'path/to/MLwiN vX.XX/')).

x64

A logical value indicating whether the 64 bit version of MLwiN is used, the default for this is determined by the version of R used. If FALSE, the 32 bit version is called.

Details

MLwiN supports conversion between MLwiN (*.wsz, *.ws), Minitab (*.mtw), SAS (*.xpt), SPSS (*.sav), and Stata (*.dta) files.

The converted data file (with a specific extension) will be saved to the file specified by foreignfile.

Examples

# NOT RUN {
# }
# NOT RUN {
library(R2MLwiN)
# NOTE: if MLwiN not saved in location R2MLwiN defaults to, specify path via:
# options(MLwiN_path = 'path/to/MLwiN vX.XX/')
# If using R2MLwiN via WINE, the path may look like this:
# options(MLwiN_path = '/home/USERNAME/.wine/drive_c/Program Files (x86)/MLwiN vX.XX/')

wsfile = normalizePath(file.path(getOption("MLwiN_path"), "samples/tutorial.ws"), winslash = "/")
## the tutorial.dta file will be saved in the temporary folder
inputfile = normalizePath(file.path(tempdir(), "tutorial.dta"), winslash = "/", mustWork = FALSE)
ws2foreign(wsfile, foreignfile = inputfile)
library(foreign)
indata = read.dta(inputfile)
str(indata)
unlink(inputfile)
