Dear R-developers, It seems to me that the position of title is usually at the bottom of a plot in sociological and political science books and articles.

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? Thanks -- Wincent Rong-gui HUANG Doctoral

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
