Some (usually older) data sets are only available in fixed-width ASCII files (.txt or .dat) that have an .sps (SPSS) or .sas (SAS) setup file explaining to the software how to read that file. These file combinations are sometimes referred to as .txt+.sps, .txt+.sas, .dat+.sps, .dat+.sas. This package allows you to read in the data if you have both the fixed-width file and its accompanying setup file.
To install this package, use the code
install.packages("asciiSetupReader")
# The development version is available on Github.
# install.packages("devtools")
devtools::install_github("jacobkap/asciiSetupReader")These parameters data and setup_file are the only ones requires to run the package though three optional parameters allow you to customize results.
data - A string containing the name of the data file
setup_file - A string containing the name of the setup file
Both files must be in your working directory or the string must contain the path to the file. Below is an example of reading in the example dataset - the original data and setup files can be found here.
data <- system.file("extdata", "example_data.zip",
package = "asciiSetupReader")
setup_file <- system.file("extdata", "example_setup.sps",
package = "asciiSetupReader")
example <- asciiSetupReader::read_ascii_setup(data = data,
setup_file = setup_file)
