Hi, 1. I've written a function to obtain significances of correlations (there is probably already a function for this, but I'm still not very familar with all the functions). This function works just fine, but there are some differences with e.g. SPSS, not large though. Maybe some floating point calculation issues [1]? Maybe someone has time to have a look, I've uploaded a working example to http://web.utanet.at/ascherst/rtest.zip (4 KB), just run test.r. 2. About Sweave, I love it! But one thing annoys me: Is it possible that it doesn't insert \begin{Schunk}...\end{Schunk}? Some of my code reads like: \ctable[ caption={Deskriptive Statistik}, label=tab:ErgebnisseDeskriptiveStatistik, pos=!tbp ]{lrrrddd} {} { \FL \multicolumn{1}{l}{} & \multicolumn{1}{r}{$N$} & \multicolumn{1}{r}{Min} & \multicolumn{1}{r}{Max} & \multicolumn{1}{r}{$M$} & \multicolumn{1}{r}{$SD$} & \multicolumn{1}{r}{Varianz} \ML <<echo=false,results=tex>>for (i in 3:ncol(scales)) { ... } @ \LL } LaTeX gives me an Error when there is an environment inside ctable. Thanks in advance. [1] http://docs.sun.com/source/806-3568/ncg_goldberg.html Stefan
