Re: [R] getting faster results

I am running algorithms for Bayesian hierarchical models with 20 or more variables or writing alogrithms that solve for partially linear models using wavlelet estimation. Soemtimes just creating the predicted vaules from the Bayesian analysis takes over a day to run!   I am just wondering if R runs faster on any particular systems or if it is about the same regardless.

I can take a dataframe with 1,000,000 rows of transaction data and compute the average and plot a histogram of the response time in less that a couple of seconds. Is that fast enough?

Can anyone answer this question. I am working with really large datasets and most of the programs I have been running take quite some time.

I heard that R may be faster in Unix. I sthis true and if so can anyone reccomend which system and requirements may allow things to go faster for?
