Dear Frank,

Dear Rafael, 1. "Does the QM-test, with an intercept in the model, evaluates if the average true outcomes of subgroups differ from the reference level or from 0?"

Dear R Users, When plotting, R by default leaves some "white space" at the top of the graph for the title. How can I get rid or reduce the size of the amount of space decicated for the title? Thanks...

Hello, outer() is great for avoiding things like: for (val1 in val1s) { for (val2 in val2s)) { x[i,j] <- somefunction(val1, val2) } } The same can be obtained with: outer(val1s, val2s, somefunction) But what if there are three (or more...

Hello All, I am trying to put a math expression into a plot title and at the same time, I want a value in the title to depend on a variable that I set earlier. Simple Example: n <- 20 plot...

Thanks to all the people who replied to my question. After trying out some of the suggestions, it seems that, in general, using outer() is really the most sensible way of going. Another suggestion was to use: x[as.character...

Hello all, Say I would like to change the outcome in a formula to a variable not part of the original dataset. This works just fine: res <- lm(mpg ~ wt + cyl, data=mtcars) res y <- rnorm(nobs(x)) update(x...

Hello All, I am wondering if there has ever been any discussion/consideration given to incorporating MathJax (or something similar) into R for rendering equations in .Rd files. I know that equations are rendered beautifully in the pdf manuals, but...

Hi All, I am trying to create a vector of expressions, where the elements in the expressions are contained in other vectors (i.e., they should be substituted). I made some attempts with substitute() and bquote(), but couldn't get...

Hello R-Helpers, plot(x, y, type="b", pch="1") plots x vs. y with both a line and the symbol "1" but how do I change the "spacing" of the symbol being plotted. In other words, I don't...

Dear Petr, Sorry, no experience with the FTH, but related to this, has anybody gotten R to interface nicely with the Retro Encabulator, providing live read outs of the synchronizing cardinal grammeters? (my apologies, I just couldn't resist) Best...
