[R] make R program faster

[Christof Kluß]

Hi

there are some good tips in "The R Inferno"
http://www.burns-stat.com/documents/books/the-r-inferno/
or connect C++ to R with Rcpp
http://dirk.eddelbuettel.com/code/rcpp.html
or byte code compiler (library(compiler))
or library(data.table)

but do you have an idea to fasten standard R source code, with the 
following Rprof output

It comes from a simulation algorithmus that calculates day wise values 
(values are depenend from the output of the day before). First I create 
a data.frame with NAs. Finally each row contains the daily values.

output <- as.data.frame(matrix(nrow = 365, ncol = 50))
for (day in (1:365)) {
   ...
   r <- list(Date=d,daylength=daylength,TempSum=tempsum, ...)
   output[day,] <- r
}

Is there an better (faster) way to do such things in R?
