[R] Analog of least significant difference error bars for proportions

Dear R-list, In the R-book, p.464, Michael Crawley recommends that error bars for bar plots of normally distributed continuous response variables with categorical explanatory variables be given by 1/2 of the least significant difference, where the least significant difference is defines

Dear R Helpers, First, I apologize for asking for help on the first of my topics. I have been looking at the posts and pages for apply, tapply etc, and I know that the solution to this must be ridiculously easy, but I just can't seem to get my brain around it. If I want to produce a set of

Hi: This isn't too hard to do. The strategy is basically this: (1) Create a list of file names. (See ?list.files for some ideas) (2) Read the data files from (1) into a list. (3) Create a function to apply to each data frame in the list. (4) Apply the function to each data frame. (5) Extract

Hi: Here's one way to do the pairwise tables. I'm restricting attention to the variables with only a few levels, but the idea should be clear enough. # Put the variable names into a vector vars - names(infert)[c(1, 3:6)] # Use expand.grid() to generate all pairs of variables # It's important to

I wrote a little function called bgfun that adds gridlines and a background, but it's not working with I plot using the formula. I have some theories on what's happening, but even if my theory is right, I don't know how to fix it. Someone have a straightforward silver bullet? Thank you, Gene
