d <- matrix(rexp(16, 2), 4)
corr <- cor(d)
sign <- symnum(cor(d), cutpoints=c(0.05, 0.01), corr = T, symbols=c("***", "**", "*"), abbr=T, diag=F)

noquote(mapply(function(x, y)paste(x, format(y, dig=3), sep=''), as.data.frame(unclass(sign)), as.data.frame(corr)))

See ?latex function in Hmisc package and also xtable package
