Discourage the weights= option of lm with summarized data
Yes. Thank you; I should have quoted it.
I suggest to remove this text or to add the word "not" at the beginning.

...e that the same
observation is repeated 'n' times. As I showed, this gives erroneous
results. Hence I suggested that it is discouraged rather than
encouraged in the Details section of lm in the Reference manual.

Use of MathJax (or something similar) in .Rd files
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 I suspect the majority of users primarily look at the html help files when using R. While I am comfortable reading something like "B_x(a,b) =

Paste() - Get all possible combinations from multiple vectors
Hello fellow R-users,
Given are three vectors and the outcome would be all possible combinations in combination with the paste() function.
For example:
x <- c(1:3)
y <- letters[1:3]
z <- LETTERS[1:3]
My result would thus be 18 names based on all possible combinations between these vectors:
"1 a A" "1 a B", "1 a C", "1 b A", "1 b B",

xyTable(x,y) versus table(x,y) with NAs
...num [1:5] 2 2 4 NA 3
$ number: int [1:5] 2 1 1 1 1
table() does not use this logic, as one NA in a vector would make all the
counts NA. Should xyTable have a way to handle NAs the way table() does?

There are a few broken links on the R website.
