yfun(x,10,20) is not a function, it's the value of a function. You can
do it with
uniroot(function(x) yfun(x,10,20),c(-100,100))
which creates the anonymous function
function(x) yfun(x,10,20)
and passes that to uniroot().

The function below prints the digits argument and
then outputs d. The code is taken from jitter.
f <- function(x){
z <- diff(r <- range(x[is.finite(x)]))
cat("digits:", 3 - floor
))
By the time you get here, z is the length of the rante of the data, so
it's 9 in your example. The rounding changes your values to
0,0,1e5, so the smallest difference is 1e5.

Another way to do this is to use the xtfrm() function. That function

Hi all,
Is srt parameter in text() not vectorized?
