Z <- seq(0, 3.99, by=0.01) q <- round(pnorm(seq(0, 3.99, by=0.01), lower=T)-0.5, 4) m <- matrix(q, ncol=10, byrow=T) rownames(m) <- format(seq(0, 3.9, by=0.1)) colnames(m) <- format(seq(0, 0.09, by=0.01)) library(xtable) xtab <- xtable(m, digits=4) print(xtab, type="html", file="normaltable.html", html.table.attributes='border="1" cellspacing="0" cellpadding="2" align="center" style="text-align: center;"')
You will need the xtable package installed to generate the HTML table.
