Thanks for help with: [R] replace() in matrix
Dear all, Thanks to Douglas Bates, Uwe Ligges, Andy Liaw, Giovanni Petris, Ryan Elmore, Mark Myatt and Guido Masarotto for answering my question on replacing cells in a matrix! Guido Masarotto even pointed me to the solution in An introduction to R. I had searched only in R for beginners. As a beginner, non-statisticians and only R user at my dept., I really appreciate the help from you all. Sincerely, Tord Sn?ll
