R Functions for LCDM Estimation

The R functions are used to build, run, and parse Mplus syntax for estimation of the LCDM. The functions to build the R syntax were created by André Rupp and Oliver Wilhelm, with additions for parsing and computing attribute reliability contributed by Jonathan Templin.

• Chapter 9 Example Data (ch9data.dat) — data from Chapter 9 of Diagnostic Measurement: Theory, Methods, and Applications
• Chapter 9 Example Q-matrix (ch9qmatrix.csv) — Q-matrix from Chapter 9
• Functions file (MplusDCM_functions.r) — put on hard disk; library of macro functions
• Example file (RDCMplus_Example.r) — example analysis file; relies on the functions file

The example will run if all files are put into the same folder.
