It turns out that when I use GUI (file-change dir) to set the working directory, R will crash. If I use setwd() instead, the example runs well.

Dear all, I try to show a subset of coefficients in my presentation. It seems that a "standard" table is not a good way to go.

Dear all, is there any function to assert whether a file path is legitimate, and to convert any potential file path to a legitimate file path? I automate a batch of files and write them to plain text files with cat(). The file argument of cat() is generated automatically which may contain characters such as ? < >, unacceptable in Windows OS. What I do at this moment is to strip such

Dear all, I have a list like this: l <- list(list(a=1,b=NULL), list(a=2,b=2)) I want to find out the elements with value of NULL and replace them with NA. The actual case has a very long list, so manually find out and replace them is not an option. I can use for loop to do this, but I want to know if there is vectorized way (or other ways) to do it?

Hi, I am wondering if some experienced users would help put the ready-to-run code of the examples in the manuals. It would help new users learn R faster by putting all the examples in an ready-to-run R script file. Can somebody help do so sometime and post the code along with the pdf manuals? http://cran.r-project.org/manuals.html Regards, Peng
