Hi All, I have am using Sweave and the \Sexpr{} to place some numeric variables in my tex document. I want to format the number prior to entry so they read slightly more elegantly. Say i have the following numbers x <- 0.00487324 y <- 0.000000432 z <- 0.567
I would like to have the numbers displayed as follows x1 <- 0.0049 y1 <- 0.00000043 z1 <- 0.57 I've seen i can use sprintf("%.3f", pi) for example to get the formating after the decimal place, but i can't figure out an elegant way to find the position of the first non-zero entry to allow me to substitute this value into the sprintf command. Can anyone offer any advise?
