Re: [R] Arcsine Tranformation.

Dear Samsad, The usual use of the arcsine transformation for proportions is arcsine-squareroot. Thus, in R, for proportions in p, you can use asin(sqrt(p)). You could have found the asin() function yourself in several ways, including help.search("arcsin"), which turns up the help page for tri

Re: [R] Has R recently made performance improvements in accumulation?

Thierry: thanks much for your feedback, and apologies for this tardy response. You pointed me in the right direction. I did not appreciate how even if the algorithm ultimately has O(n^2) behavior, it can take a big n to overcome large coefficents on lower order terms (e.g. the O(1) and O(n) par

Re: [R] cpquery problem

Hi Marco Thanks for your prompt reply. First, I have been using the parse(eval()) convention because I saw it used in some example code for running cpquery, but am happy to drop this practice. I have tried running the cpquery in the debug mode, and found that it typically returns the following f

Hi Jeff, many thanks, that one is the Speedy Gonzalles out of all. Can also do some FUN stuff. aggregate.nx.ny.array.aperm <- function( dta, nx = 2, ny = 2, FUN=colMeans, ... ) { # number of rows in result nnr <- nrow( dta ) %/% ny # number of columns in result nnc <- ncol( dta ) %/% nx #
