Read in .sav of SPSS file to R by epicalc 'use'
by Virasakdi Chongsuvivatwong - Monday, 12 October 2009, 07:31 PM
 

By default, the read.spss function from the foreign package reads in ".sav" files of SPSS in a list format, which keeps all the information but is difficult to use thereafter.

Epicalc's use function reads in SPSS files in a data frame format, keeps all the variable labels as variable descriptions in Epicalc type, and replaces the values commented in SPSS as missing or value labels for a continuous variable into NA.

Analysis of Longitudinal Data: RE704
by Edward McNeil - Thursday, 10 September 2009, 04:41 PM
  Dear participants,

On Monday, September 21st we will open the Longitudinal Data Analysis course (RE704). All past graduates of our free Internet courses are welcome to join this new course and contribute to the discussion forum.

http://medipe.psu.ac.th/elearning

The enrolment key for this course is: correlation

The course will cover topics such as exploration and graphical display, area under the curve (AUC) approach, analysis of individual growth rates, handling missing records and modelling techniques (marginal models, random effects models, transition models).

Please download the latest version of R and Epicalc from the CRAN web site. We hope to see you all online.

Best wishes,

Edward McNeil
