matrix elementwise average with NA's
...t;- matrix(c(1:5,rep(NA,5), 6:10), nrow=3, byrow=T) mat2 <- matrix(c(2:6, 6:10, rep(NA,5)), nrow=3, byrow=T) I'd like to compute the element-wise average for non-NA entries. Of course (mat1+mat2)/2 does not work for the final two rows because of the NA's. Are there any elegant ways to accopmlish this without writing a loop with indices? Thanks in advance for any assistance. Greg --------------------------------- [[alternative HTML version deleted]]

post hoc analysis after anova
...t;1", "3" etc )at the same time and get statistics for each factor's levels. The statistics I want is just the basic one such as mean standard error. I tried the "pairwise.t.test", but I could not do what I wnated to. I was wondering if anyone has idea about how I can accopmlish this task? Thanks a lot for your tips and help Greetings Mahdi -- ----------------------------------- Mahdi Osman (PhD) E-mail: m_osm at gmx.net

Text Summarization
Is there a text mining/ NLP package in R that could do text summarization? For example, take a huge text as input and provide a summary of the text. In package tm, summarization is defined more as high frequency terms which is not what I want. I actually want a summary of what is present in the huge volume of text. Any help on a R package would be helpful. Thank you. Ravi -- View this message
