search for: loadcache

Hi. I have a procedure that reads a directory, loops through a set of particular .RData files, loading each one, and feeding its object(s) into a function, as follows: cvListFiles<-list.files(fnDir); for(i in grep(paste("^",pfnStub,".*\\.RData$",sep=""),cvListFiles)){ load(paste(fnDir,cvListFiles[i],sep="/")); myFunction(rliObject); rm(rliObject); };

...t way to work with multiple separate outputs which one would like to compare? (I have read something about environments, but I understood it's only for functions. I could create environments, but was not succesful in using them at all (location change or separate sandbox). Functions saveCache, loadCache, saveObject, loadObject is not really what I have in mind, too -- saveObject(list=ls(), "NewObjectFile") is not a solution either...) Thanks for any hint in advance.

Hi: I am working on a publication and I have heard about LaTEX but I haven't actually tried to learn about it until today. I've found a few examples but I can't actually make them work properly. I have a couple of questions: Does LATEX have to be installed on your computer? How does the xtable package and Sweave work together? How can I make the code below create a table as pdf file?
